SCB变压器与SC变压器的区别
SCB变压器与SC变压器的区别一、线圈绕制方面：SCB型产品低压线圈采用箔绕：（1）绕组结构：采用铜箔单层缠绕，层间材料用含有潜伏性固化剂的环氧树脂及F级复合箔。
（2）绕组材料：采用导电率极佳的无氧铜，含铜量99.99%。
SC型产品低压线圈采用线绕：（1）绕组结构：圆筒式线圈（2）多根普通玻璃丝包扁铜线。
二、抗突发短路事故方面：（1）SCB型产品低压采用铜箔式结构，电抗高度即为绕组高度，与高压线圈等同，从而在变压器产生突发短路条件下，产生较小的轴向短路力。
另外，由于整个绕组采用一张宽而薄的箔材，抗轴向拉断能力较强。
（2）SC型产品由于采用多根并绕，端部螺旋角极大，产生很强的端部漏磁场，在变压器遭受突发短路状态下，产生极大的短路力，如果结构方面没有充分加强，则很容易造成轴向损坏。
三、在变压器低压温升方面由于低压绕组靠近铁芯散热较困难，SCB型产品采用箔式低压绕组结构，可以方便的设置散热面，加大通风量，从而保证线圈产生的热量及时散发。
而SC型产品采用线绕式低压绕组，达到上述目的较为困难。
变压器的低压温升，箔绕结构要比线绕结构平均下降5—7K。
可提高变压器的过负载能力和使用寿命。
四、在变压器的负载损耗方面由于SCB型产品低压箔式结构采用无氧铜箔，同电压等级，同规格的变压器，SCB型产品比SC型产品，由于集肤效应造成的，附加损耗平均降低5%。
（5）绝缘性能方面SCB型产品低压箔式结构采用低压箔式结构，低压绕组内各层间的电压梯度很低，SCB型产品与SC型产品相比具有更高的绝缘强度。
由于其匝间电容较大，从而提高产品抗过电压及雷电冲击强度。
SCB9-3150/35±2x2.5%/0.4kV，Uk%=8 Y，d11请问这个变压器参数具体都是什么意思？这是环氧树脂干式变压器：其意义如下：S-三相；C-环氧树脂浇注型B-为铜箔线圈9-设计序号9型代表损耗标准（这是目前比较差的）3150kVA-是变压器的额定容量35kV-是变压器的输入额定电压（高压）+-2*2.5%-是高压的分接调压范围：高压有36750、35875、35000、34125、33250V五档电压可以调节。

It contains all of the functions required to implement a full−featured, open loop, three or four phase motor control system. In addition, the controller can be made to operate DC brush motors. Constructed with Bipolar Analog technology, it offers a high degree of performance and ruggedness in hostile industrial environments. The MC33035 contains a rotor position decoder for proper commutation sequencing, a temperature compensated reference capable of supplying a sensor power, a frequency programmable sawtooth oscillator, a fully accessible error amplifier, a pulse width modulator comparator, three open collector top drive outputs, and three high current totem pole bottom driver outputs ideally suited for driving power MOSFETs. Included in the MC33035 are protective features consisting of undervoltage lockout, cycle−by−cycle current limiting with a selectable time delayed latched shutdown mode, internal thermal shutdown, and a unique fault output that can easily be interfaced to a microprocessor controller. Typical motor control functions include open loop speed control, forward or reverse rotation, run enable, and dynamic braking. In addition, the MC33035 has a 60°/120°select pin which configures the rotor position decoder for either 60° or 120° sensor electrical phasing inputs. FUNCTIONAL DESCRIPTIONA representative internal block diagram is shown in Figure 19 with various applications shown in Figures 36, 38, 39, 43, 45, and 46. A discussion of the features and function of each of the internal blocks given below is referenced to Figures 19 and 36.Rotor Position DecoderAn internal rotor position decoder monitors the three sensor inputs (Pins 4, 5, 6) to provide the proper sequencing of the top and bottom drive outputs. The sensor inputs are designed to interface directly with open collector type Hall Effect switches or opto slotted couplers. Internal pull−up resistors are included to minimize the required number of external components. The inputs are TTL compatible, with their thresholds typically at 2.2 V. The MC33035 series is designed to control three phase motors and operate with four of the most common conventions of sensor phasing. A 60°/120°Select (Pin 22) is conveniently provided and affords the MC33035 to configure itself to control motors having either 60°, 120°, 240° or 300° electrical sensor phasing. With three sensor inputs there are eight possible input code combinations, six of which are valid rotor positions. The remaining two codes are invalid and are usually caused by an open or shorted sensor line. With six valid input codes, the decoder can resolve the motor rotor position to within a window of 60 electrical degrees.The Forward/Reverse input (Pin 3) is used to change the direction of motor rotation by reversing the voltage across the stator winding. When the input changes state, from high to low with a given sensor input code (for example 100), the enabled top and bottom drive outputs with the same alpha designation are exchanged (A T to A B, B T to B B, C T to C B). In effect, the commutation sequence is reversed and the motor changes directional rotation.Motor on/off control is accomplished by the Output Enable (Pin 7). When left disconnected, an internal 25 µA current source enables sequencing of the top and bottom drive outputs. When grounded, the top drive outputs turn off and the bottom drives are forced low, causing the motor to coast and the Fault output to activate.Dynamic motor braking allows an additional margin of safety to be designed into the final product. Braking is accomplished by placing the Brake Input (Pin 23) in a high state. This causes the top drive outputs to turn off and the bottom drives to turn on, shorting the motor−generated back EMF. The brake input has unconditional priority over all other inputs. The internal 40 kΩ pull−up resistor simplifies interfacing with the system safety−switch by insuring brake activation if opened or disconnected. The commutation logic truth table is shown in Figure 20. A four input NOR gate is used to monitor the brake input and the inputs to the three top drive output transistors. Its purpose is to disable braking until the top drive outputs attain a high state. This helps to prevent simultaneous conduction of the the top and bottom power switches. In half wave motor drive applications, the top drive outputs are not required and are normally left disconnected. Under these conditions braking will still be accomplished since the NOR gate senses the base voltage to the top drive output transistors.Error AmplifierA high performance, fully compensated error amplifier with access to both inputs and output (Pins 11, 12, 13) is provided to facilitate the implementation of closed loop motor speed control. The amplifier features a typical DC voltage gain of 80 dB, 0.6 MHz gain bandwidth, and a wide input common mode voltage range that extends from ground to V ref. In most open loop speed control applications, the amplifier is configured as a unity gain voltage follower with the noninverting input connected to the speed set voltage source. Additional configurations are shown in Figures 31 through 35.OscillatorThe frequency of the internal ramp oscillator is programmed by the values selected for timing components R T and C T. Capacitor C T is charged from the Reference Output (Pin 8) through resistor R T and discharged by an internal discharge transistor. The ramp peak and valley voltages are typically 4.1 V and 1.5 V respectively. To provide a good compromise between audible noise and output switching efficiency, an oscillator frequency in the range of 20 to 30 kHz is recommended. Refer to Figure 1 for component selection.Figure 19. Representative Block DiagramNOTES:1.V = Any one of six valid sensor or drive combinations X = Don’t care.2.The digital inputs (Pins 3, 4, 5, 6, 7, 22, 23) are all TTL compatible.

Three Phase, Six Step Commutation Truth Table (Note 1)Pulse Width ModulatorThe use of pulse width modulation provides an energy efficient method of controlling the motor speed by varying the average voltage applied to each stator winding during the commutation sequence. As C T discharges, the oscillator sets both latches, allowing conduction of the top and bottom drive outputs. The PWM comparator resets the upper latch, terminating the bottom drive output conduction when the positive−going ramp of C T becomes greater than the error amplifier output. The pulse width modulator timing diagram is shown in Figure 21. Pulse width modulation for speed control appears only at the bottom drive outputs.Current LimitContinuous operation of a motor that is severely over−loaded results in overheating and eventual failure. This destructive condition can best be prevented with the use of cycle−by−cycle current limiting. That is, each on−cycle is treated as a separate event. Cycle−by−cycle current limiting is accomplished by monitoring the stator current build−up each time an output switch conducts, and upon sensing an over current condition, immediately turning off the switch and holding it off for the remaining duration of oscillator ramp−up period. The stator current is converted to a voltage by inserting a ground−referenced sense resistor R S (Figure 36) in series with the three bottom switch transistors (Q4, Q5, Q6). The voltage developed across the sense resistor is monitored by the Current Sense Input (Pins 9 and 15), and compared to the internal 100 mV reference. The current sense comparator inputs have an input common mode range of approximately 3.0 V. If the 100 mV current sense threshold is exceeded, the comparator resets the lower sense latch and terminates output switch conduction. The value for the current sense resistor is:R S+0.1I stator(max)The Fault output activates during an over current condition. The dual−latch PWM configuration ensures that only one single output conduction pulse occurs during any given oscillator cycle, whether terminated by the output of the error amp or the current limit comparator.Figure 21. Pulse Width Modulator Timing Diagram Current Sense Input Capacitor C T Error Amp Out/PWMInput Latch Set"Inputs Top Drive Outputs Bottom DriveOutputsFault OutputReferenceThe on−chip 6.25 V regulator (Pin 8) provides charging current for the oscillator timing capacitor, a reference for the error amplifier, and can supply 20 mA of current suitable for directly powering sensors in low voltage applications. In higher voltage applications, it may become necessary to transfer the power dissipated by the regulator off the IC. This is easily accomplished with the addition of an external pass transistor as shown in Figure 22. A 6.25 V reference level was chosen to allow implementation of the simpler NPN circuit, where V ref − V BE exceeds the minimum voltage required by Hall Effect sensors over temperature. With proper transistor selection and adequate heatsinking, up to one amp of load current can be obtained.Figure 22. Reference Output BuffersThe NPN circuit is recommended for powering Hall or opto sensors, where the output voltage temperature coefficient is not critical. The PNP circuit is slightly more complex, but is also more accurate over temperature. Neither circuit has current limiting.V V and Sensor Power6.25 VUndervoltage LockoutA triple Undervoltage Lockout has been incorporated to prevent damage to the IC and the external power switch transistors. Under low power supply conditions, it guarantees that the IC and sensors are fully functional, and that there is sufficient bottom drive output voltage. The positive power supplies to the IC (V CC ) and the bottom drives (V C ) are each monitored by separate comparators that have their thresholds at 9.1 V . This level ensures sufficient gate drive necessary to attain low R DS(on) when driving standard power MOSFET devices. When directly powering the Hall sensors from the reference, improper sensor operation can result if the reference output voltage falls below 4.5 V . A third comparator is used to detect this condition. If one or more of the comparators detects an undervoltage condition, the Fault Output is activated, the top drives are turned off and the bottom drive outputs are held in a low state. Each of the comparators contain hysteresis to prevent oscillations when crossing their respective thresholds.Fault OutputThe open collector Fault Output (Pin 14) was designed to provide diagnostic information in the event of a system malfunction. It has a sink current capability of 16 mA and can directly drive a light emitting diode for visual indication.Additionally, it is easily interfaced with TTL/CMOS logic for use in a microprocessor controlled system. The Fault Output is active low when one or more of the following conditions occur:1)Invalid Sensor Input code 2)Output Enable at logic [0]3)Current Sense Input greater than 100 mV4)Undervoltage Lockout, activation of one or more of the comparators5)Thermal Shutdown, maximum junction temperature being exceededThis unique output can also be used to distinguish between motor start−up or sustained operation in an overloaded condition. With the addition of an RC network between the Fault Output and the enable input, it is possible to create a time−delayed latched shutdown for overcurrent. The added circuitry shown in Figure 23 makes easy starting of motor systems which have high inertial loads by providing additional starting torque, while still preserving overcurrent protection. This task is accomplished by setting the current limit to a higher than nominal value for a predetermined time.During an excessively long overcurrent condition, capacitor C DLY will charge, causing the enable input to cross its threshold to a low state. A latch is then formed by the positive feedback loop from the Fault Output to the Output Enable.Once set, by the Current Sense Input, it can only be reset by shorting C DLY or cycling the power supplies.Drive OutputsThe three top drive outputs (Pins 1, 2, 24) are open collector NPN transistors capable of sinking 50 mA with a minimum breakdown of 30 V. Interfacing into higher voltage applications is easily accomplished with the circuits shown in Figures 24 and 25.The three totem pole bottom drive outputs (Pins 19, 20, 21) are particularly suited for direct drive of N−Channel MOSFETs or NPN bipolar transistors (Figures 26, 27, 28 and 29). Each output is capable of sourcing and sinking up to 100 mA. Power for the bottom drives is supplied from V C (Pin 18). This separate supply input allows the designer added flexibility in tailoring the drive voltage, independent of V CC. A zener clamp should be connected to this input when driving power MOSFETs in systems where V CC is greater than 20 V so as to prevent rupture of the MOSFET gates.The control circuitry ground (Pin 16) and current sense inverting input (Pin 15) must return on separate paths to the central input source ground.Thermal ShutdownInternal thermal shutdown circuitry is provided to protect the IC in the event the maximum junction temperature is exceeded. When activated, typically at 170°C, the IC acts as though the Output Enable was grounded.Figure 23. Timed Delayed Latched Over Current ShutdownFigure 24. High Voltage Interface withNPN Power TransistorsTransistor Q1 is a common base stage used to level shift from V CC to the high motor voltage, V M. The collector diode is required if V CC is present while V M is low.[R DLY C DLY Inǒ6.25–(20x10–6R DLY)1.4–(20x10R DLY)ǓFigure 25. High Voltage Interface withN−Channel Power MOSFETsFigure 26.

The control loop is closed as the forced air cools the NTC thermistor. For controlled heating applications, ex-change the positions of R1 and R2.Figure 35. Closed Loop Temperature ControlSYSTEM APPLICATIONSThree Phase Motor CommutationThe three phase application shown in Figure 36 is a full−featured open loop motor controller with full wave, six step drive. The upper power switch transistors are Darlingtons while the lower devices are power MOSFETs. Each of these devices contains an internal parasitic catch diode that is used to return the stator inductive energy back to the power supply. The outputs are capable of driving a delta or wye connected stator, and a grounded neutral wye if split supplies are used. At any given rotor position, only one top and one bottom power switch (of different totem poles) is enabled. This configuration switches both ends of the stator winding from supply to ground which causes the current flow to be bidirectional or full wave. A leading edge spike is usually present on the current waveform and can cause a current−limit instability. The spike can be eliminated by adding an RC filter in series with the Current Sense Input. Using a low inductance type resistor for R S will also aid in spike reduction. Care must be taken in the selection of the bottom power switch transistors so that the current during braking does not exceed the device rating. During braking, the peak current generated is limited only by the series resistance of the conducting bottom switch and winding.I peak+V M)EMFswitch)R windingIf the motor is running at maximum speed with no load, the generated back EMF can be as high as the supply voltage, and at the onset of braking, the peak current may approach twice the motor stall current. Figure 37 shows the commutation waveforms over two electrical cycles. The first cycle (0° to 360°) depicts motor operation at full speed while the second cycle (360° to 720°) shows a reduced speed with about 50% pulse width modulation. The current waveforms reflect a constant torque load and are shown synchronous to the commutation frequency for clarity.Figure 36. Three Phase, Six Step, Full Wave Motor ControllerFigure 37.

This configuration is ideally suited for automotive and other low voltage applications since there is only one power switch voltage drop in series with a given stator winding. Current flow is unidirectional or half wave because only one end of each winding is switched. Continuous braking with the typical half wave arrangement presents a motor overheating problem since stator current is limited only by the winding resistance. This is due to the lack of upper power switch transistors, as in the full wave circuit, used to disconnect the windings from the supply voltage V M. A unique solution is to provide braking until the motor stops and then turn off the bottom drives. This can be accomplished by using the Fault Output in conjunction with the Output Enable as an over current timer. Components R DLY and C DLY are selected to give the motor sufficient time to stop before latching the Output Enable and the top drive AND gates low. When enabling the motor, the brake switch is closed and the PNP transistor (along with resistors R1 and R DLY) are used to reset the latch by discharging C DLY. The stator flyback voltage is clamped by a single zener and three diodes.Figure 38. Three Phase, Three Step, Half Wave Motor ControllerThree Phase Closed Loop ControllerThe MC33035, by itself, is only capable of open loop motor speed control. For closed loop motor speed control, the MC33035 requires an input voltage proportional to the motor speed. Traditionally, this has been accomplished by means of a tachometer to generate the motor speed feedback voltage. Figure 39 shows an application whereby an MC33039, powered from the 6.25 V reference (Pin 8) of the MC33035, is used to generate the required feedback voltage without the need of a costly tachometer. The same Hall sensor signals used by the MC33035 for rotor position decoding are utilized by the MC33039. Every positive or negative going transition of the Hall sensor signals on any of the sensor lines causes the MC33039 to produce an output pulse of defined amplitude and time duration, as determined by the external resistor R1 and capacitor C1. The output train of pulses at Pin 5 of the MC33039 are integrated by the error amplifier of the MC33035 configured as an integrator to produce a DC voltage level which is proportional to the motor speed. This speed proportional voltage establishes the PWM reference level at Pin 13 of the MC33035 motor controller and closes the feedback loop. The MC33035 outputs drive a TMOS power MOSFET 3−phase bridge. High currents can be expected during conditions of start−up, breaking, and change of direction of the motor.The system shown in Figure 39 is designed for a motor having 120/240 degrees Hall sensor electrical phasing. The system can easily be modified to accommodate 60/300 degree Hall sensor electrical phasing by removing the jumper (J2) at Pin 22 of the MC33035.Figure 39.

An external crystal is recommended to provide a precision time reference.The converter accepts 3.15 V p-p ± 27% input signals, in the range of 10 kHz to 20 kHz on the Sin and Cos inputs. A Type II servo loop is employed to track the inputs and convert the input Sin and Cos information into a digital representation of the input angle and velocity. The maximum tracking rate of the converter is set internally by the input clock frequency. The nominal clock frequency is 8.192MHz which allows a tracking rate of 1,000rps. However by increasing the clock frequency to 10.24MHz a maximum tracking rate of 1,250 rps can be achieved.FUNCTIONAL BLOCK DIAGRAMFigure 1.AD2S1205Preliminary Technical DataRev.PrB | Page 2 of 25APPLICATIONSElectric power steering Electric vehiclesIntegrated starter generator/alternator Encoder emulationAutomotive motion sensing and controlPRODUCT HIGHLIGHTS•Complete Resolver-to-Digital Interface: The AD2S1205 provides the complete solution for digitizing resolver signals (12-bit resolution) with on-board programmable sinusoidal oscillator.•Ratiometric Tracking Conversion: This technique provides continuous output position data without conversion delay.

Classical Resolver vs. Variable Reluctance ResolverA resolver is a rotating transformer typically with a primary winding on the rotor and two secondary windings on the stator. In the case of a variable reluctance resolver, there are no wind-ings on the rotor as shown in Figure 3. The primary winding is on the stator as well as the secondary windings, but the saliency in the rotor design provides the sinusoidal variation in the secondary coupling with the angular position. Either way, the resolver output voltages (S3–S1, S2–S4) will have the same equations as shown in Equation 1.AmplitudeExcitation Rotor E FrequencyExcitation Rotor t Sin AngleShaft Cos t Sin E S S Sin t Sin E S S ===×=−×=−0004213ωθθωθω Equation 1.The stator windings are displaced mechanically by 90° (see Figure 3). The primary winding is excited with an ac reference. The amplitude of subsequent coupling onto the stator secon-dary windings is a function of the position of the rotor (shaft) relative to the stator. The resolver, therefore, produces two output voltages (S3–S1, S2–S4) modulated by the Sine and Cosine of shaft angle. Resolver format signals refer to the signals derived from the output of a resolver as shown in Equation 1. Figure 4 illustrates the output format.04406-0-0040°90°180°θ270°360°Figure 4. Electrical Resolver RepresentationPreliminary Technical DataAD2S1205Rev. PrB | Page 9 of 25PRINCIPLE OF OPERATIONThe AD2S1205 operates on a Type II tracking closed-loop principle. The output continually tracks the position of the resolver without the need for external convert and wait states. As the resolver moves through a position equivalent to the least significant bit weighting, the output is updated by one LSB. The converter tracks the shaft angle θ by producing an output angle ϕ that is fed back and compared to the input angle θ, and the resulting error between the two is driven towards 0 when the converter is correctly tracking the input angle. To measure the error, S3–S1 is multiplied by Cosϕ and S2–S4 is multiplied by Sinϕ to give423100S to S Sin Cos t Sin E S to S Cos Sin t Sin E φθωφθω××The difference is taken, giving)(0φθ−φθ×ωSin Cos Cos Sin t Sin EEquation 2.This signal is demodulated using the internally generated synthetic reference, yielding)(0φθφθSin Cos Cos Sin E −Equation 3.Equation 3 is equivalent to E 0 Sin (θ − ϕ), which isapproximately equal to E 0 (θ − ϕ) for small values of θ − ϕ, where θ − ϕ = angular error.The value E 0 (θ − ϕ) is the difference between the angular error of the rotor and the converter’s digital angle output.A phase-sensitive demodulator, integrators, and a compensation filter form a closed-loop system that seeks to null the error signal. When this is accomplished, ϕ equals the resolver angle θ within the rated accuracy of the converter. A Type II tracking loop is used so that constant velocity inputs can be tracked without inherent error.For more information about the operation of the converter, see the Circuit Dynamics section.FAULT DETECTION CIRCUITThe AD2S1205 fault detection circuit will detect loss of resolver signals, out of range input signals, input signal mismatch, or loss of position tracking. In these cases, the position indicated by the AD2S1205 may differ significantly from the actual shaft position of the resolver.Monitor SignalThe AD2S1205 generates a monitor signal by comparing the angle in the position register to the incoming Sin and Cos signals from the resolver. The monitor signal is created in a similar fashion to the error signal described in the Principle of Operation section. The incoming signals Sin θ and Cos θ are multiplied by the Sin and Cos of the output angle, respectively, and then added together as shown below:φ×θ×+φθ×=Cos Cos A Sin x Sin A Monitor 21Equation 4.Where A1 is the amplitude of the incoming Sin signal (A1 × Sin θ), A2 is the amplitude of the incoming Cos signal (A2 × Cos θ), θ is the resolver angle, and ϕ is the angle stored in the position register. Note that Equation 4 is shown after demodula-tion, with the carrier signal Sin ωt removed. Also note that for matched input signal (i.e., no-fault condition), A1 = A2. When A1 = A2 and the converter is tracking (θ = ϕ), themonitor signal output has a constant magnitude of A1 (Monitor = A1 × (Sin 2 θ + Cos 2 θ) = A1), independent of shaft angle. When A1 ≠ A2, the monitor signal magnitude varies between A1 and A2 at twice the rate of shaft rotation. The monitor signal is used as described in the following sections to detect degradation or loss of input signals.Loss of Signal DetectionLoss of signal (LOS) is detected when either resolver input (Sin or Cos) falls below the specified LOS Sin/Cos threshold bycomparing the monitor signal to a fixed minimum value. LOS is indicated by both DOS and LOT latching as logic low outputs. The DOS and LOT pins are reset to the no fault state by a rising edge of SAMPLE . The LOS condition has priority over both the DOS and LOT conditions, as shown in Table 4. LOS is indicated within 45° of angular output error worst case.AD2S1205Preliminary Technical DataRev.PrB | Page 10 of 25Signal Degradation DetectionDegradation of signal (DOS) is detected when either resolver input (Sin or Cos) exceeds the specified DOS Sin/Cos threshold by comparing the monitor signal to a fixed maximum value. DOS is also detected when the amplitude of the input signals Sin and Cos mismatch by more than the specified DOS Sin/ Cos mismatch by continuously storing the minimum andmaximum magnitude of the monitor signal in internal registers, and calculating the difference between the minimum andmaximum. DOS is indicated by a logic low on the DOS pin, and is not latched when the input signals exceed the maximum input level. When DOS is indicated due to mismatched signals, the output is latched low until a rising edge of SAMPLE resets the stored minimum and maximum values. The DOS condition has priority over the LOT condition, as shown in Table 4. DOS is indicated within 30° of angular output error worst case.Loss of Position Tracking DetectionLoss of tracking (LOT) is detected for three separate conditions: • When the internal error signal of the AD2S1205 has exceeded 5°• When the input signal exceeds the maximum tracking rate of 60,000 rpm (1,000 rps)•When the internal position (at the position integrator) differs from the external position (at the position register) by more than 5°LOT is indicated by a logic low on the LOT pin, and is not latched. LOT has a 4° hysteresis, and is not cleared until the internal error signal or internal/external position mismatch is less than 1°. When the maximum tracking rate is exceeded, LOT is cleared when both the velocity is less than 1,000 rps and the internal/external position mismatch is less than 1°. LOT can be indicated for step changes in position (such as after a RESET signal is applied to the AD2S1205), or for accelerations >~85,000 rps 2. LOT is useful as a built-in test (BIT) that the tracking converter is functioning properly. The LOT condition has lower priority than both the DOS and LOS conditions as shown in Table 4. The LOT and DOS conditions cannot be indicated at the same time.Table 4. Fault Detection DecodingCondition DOS LOT Priority Loss of Signal0 0 1 Degradation of Signal 0 1 2 Loss of Tracking 1 0 3 No Fault1 1Responding to a Fault ConditionIf any fault condition (LOS, DOS, or LOT) is indicated by the AD2S1205, the output data must be presumed to be invalid. This means that even if a RESET or SAMPLE pulse releases the fault condition, the output data may be corrupted, even though a fault may not be immediately indicated after the RESET / SAMPLE event. As discussed earlier, there are some fault conditions with inherent latency. If the device fault is cleared, there could be some latency in the resolver’s mechanical position before the fault condition is re-indicated.When a fault is indicated, all output pins will still provide data, although the data may or may not be valid. The fault condition will not force the parallel, serial, or encoder outputs to a known state.Response to specific fault conditions is a system-levelrequirement. The fault outputs of the AD2S1205 indicate that the device has sensed a potential problem with either the internal or external signals of the AD2S1205. It is the responsibility of the system designer to implement theappropriate fault-handling schemes within the control hardware and/or algorithm of a given application based on the indicated fault(s) and the velocity or position data provided by the AD2S1205.False Null ConditionResolver-to-digital converters that employ Type II tracking loops based on the error equation (Equation 3) presented in the Principle of Operation section can suffer from a condition known as “false null.” This condition is caused by a metastable solution to the error equation when θ − ϕ = 180°. The AD2S1205 is not susceptible to this condition because its hysteresis is implemented externally to the tracking loop.Because of the loop architecture chosen for the AD2S1205, the internal error signal always has some movement (1 LSB per clock cycle), and so, in a metastable state, the converter will always move to an unstable condition within one clock cycle, causing the tracking loop to respond to the false null condition as if it were a 180° step change in input position (the response time is the same as specified in Dynamic Performance section of Table 1). Therefore, it is impossible to enter the metastable condition any time after the startup sequence as long as the resolver signals are valid.Preliminary Technical DataAD2S1205Rev. PrB | Page 11 of 25CONNECTING THE CONVERTERRefer to Figure 5. Ground should be connected to the AGND pin and DGND pin. Positive power supply V DD = +5 V dc ± 5% should be connected to the AV DD pin and DV DD pin. Typical values for the decoupling capacitors are 10 nF and 4.7 μF, respectively. These capacitors should be placed as close to the device pins as possible, and should be connected to both AV DD and DV DD . If desired, the reference oscillator frequency can be changed from the nominal value of 10 kHz using FS1 and FS2. Typical values for the oscillator decoupling capacitors are 20 pF. Typical values for the reference decoupling capacitors are 10 μF and 0.01 μF, respectively.Figure 5. Connecting the AD2S1205 to a ResolverThe gain of the buffer depends on the type of resolver used. Since the specified excitation output amplitudes are matched to the specified Sin/Cos input amplitudes, the gain of the buffer is determined by the attenuation of the resolver.In this recommended configuration, the converter introduces a V REF /2 offset in the Sin, Cos signals coming from the resolver. Of course, the SinLO and CosLO signals may be connected to a different potential relative to ground, as long as the Sin and Cos signals respect the recommended specifications. Note that since the EXC/EXC outputs are differential, there is an inherent gain of 2×.For example, if the primary to secondary turns ratio is 2:1, the buffer will have unity gain. Likewise, if the turns ratio is 5:1, the gain of the buffer should be 2.5×. Figure 6 suggests a buffer circuit.

To achieve the dynamic performance specified, an 8.192 MHz crystal must be used.AD2S1205Preliminary Technical DataRev.PrB | Page 12 of 25ABSOLUTE POSITION AND VELOCITY OUTPUTThe angular position and angular velocity are represented by binary data and can be extracted either via a 12-bit parallel interface or a 3-wire serial interface that operates at clock rates up to 25 MHz. The chip select pin, CS , must be held low to enable the device. Angular position and velocity can be selected using a dedicated polarity input, RDVEL .SOE InputThe serial output enable pin, SOE , is held high to enable the parallel interface. The SOE pin is held low to enable the serial interface, which places pins (DB0–DB9) in the high impedance state, while DB11 is the serial output (SO), and DB10 is the serial clock input (SCLK).Data FormatThe digital angle signal represents the absolute position of the resolver shaft as a 12-bit unsigned binary word. The digital velocity signal is a 12-bit twos complement word, whichrepresents the velocity of the resolver shaft rotating in either a clockwise or a counterclockwise direction.Finally, the RD input is used to read the data from the output register and to enable the output buffer. The timingrequirements for the read cycle are illustrated in Figure 7.SAMPLE InputData is transferred from the position and velocity integrators respectively to the position and velocity registers following a high to low transition of the SAMPLE signal. This pin must be held low for at least t 1 ns to guarantee correct latching of the data. RD should not be pulled low before this time. Also, a rising edge of SAMPLE resets the internal registers that contain the minimum and maximum magnitude of the monitor signal.PARALLEL INTERFACEThe angular position and angular velocity are available on the AD2S1205 in two 12-bit registers, which can be accessed via the 12-bit parallel port. The parallel interface is selected holding the SOE pin high. Data is transferred from the velocity and position integrators, respectively, to the position and velocity registers following a high-to-low transition on the SAMPLE pin. The RDVEL polarity pin selects which register from the position or the velocity registers is transferred to the output register. The CS pin must be held low to transfer the selected data register to the output register. Finally, the RD input is used to read the data from the output register and to enable the output buffer. The timing requirements for the read cycle are shown in Figure 7.SAMPLE InputData is transferred from the position and velocity integrators, respectively, to the position and velocity registers following a high-to-low transition on the SAMPLE signal. This pin must be held low for at least t 1 ns to guarantee correct latching of the data. RD should not be pulled low before this time since data would not be ready. The converter will continue to operate during the read process. Also, a rising edge of SAMPLE resets the internal registers that contain the minimum and maximum magnitude of the monitor signal.CS InputThe device will be enabled when CS is held low.RDVEL InputRDVEL input is used to select between the angular position and velocity registers as shown in Figure 7. RDVEL is held high for angular position and low for angular velocity. The RDVEL pin must be set (stable) at least t 4 ns before the RD pin is pulled low.RD InputThe 12-bit data bus lines are normally in a high impedance state. The output buffer is enabled when CS and RD are held low. A falling edge of the RD signal transfers data to the output buffer. The selected data is made available to the bus to be read within t 6 ns of the RD pin going low. The data pins will return to high impedance state when the RD returns to high state, within t 7 ns. If the user is reading data continuously, RD can be reapplied a minimum of t 3 ns after it was released.Preliminary Technical Data AD2S1205Figure 7. Parallel Port Read TimingRev. PrB | Page 13 of 25AD2S1205Preliminary Technical DataRev.PrB | Page 14 of 25SERIAL INTERFACEThe angular position and angular velocity are available on the AD2S1205 in two 12-bit registers. These registers can be accessed via a 3-wire serial interface, SO, RD , and SCLK, that operates at clock rates up to 25 MHz and is compatible with SPI and DSP interface standards. The serial interface is selected by holding low the SOE pin. Data from the position and velocity integrators are first transferred to the position and velocity registers, using the SAMPLE pin. The RDVEL polarity pin selects which register from the position or the velocity registers is transferred to the output register. The CS pin must be held low to transfer the selected data register to the output register. Finally, the RD input is used to read the data that will be clocked out of the output register and will be available on the serial output pin, SO. When the serial interface is selected, DB11 is used as the serial output pin, SO, and DB10 is used as the serial clock input, SCLK, while pins DB0–DB9 are placed in the high impedance state. The timing requirements for the read cycle are described in Figure 8.SO OutputThe output shift register is 16-bit wide. Data is shifted out of the device as a 16-bit word under the control of the serial clock input, SCLK. The timing diagram for this operation is shown in Figure 8. The 16-bit word consists of 12 bits of angular data (position or velocity depending on RDVEL input), one RDVEL status bit and three status bits, a parity bit, degradation of signal bit, and loss of tracking bit. Data is read out MSB first (bit 15) on the SO pin. Bit 15 through bit 4 correspond to the angular information. The angular position data format is unsigned binary, with all zeros corresponding to 0 degrees and all ones corresponding to 360 degrees –l LSB. The angular velocity data format instead is twos complement binary, with the MSB representing the rotation direction. Bit 3 is the RDVEL status bit, 1 indicating position and 0 indicating velocity. Bit 2 is DOS, the degradation of signal flag (refer to the Fault Detection Circuit section). Bit 1 is LOT, the loss of tracking flag (refer to the Fault Detection Circuit section). Bit 0 is PAR, the parity bit: both position and velocity data are odd parity format; the data read out will always contain an odd number of logic highs (1s). SAMPLE InputData is transferred from the position and velocity integrators, respectively, to the position and velocity registers following a high-to-low transition on the SAMPLE signal. This pin must be held low for at least t 1 ns to guarantee correct latching of the data. RD should not be pulled low before this time since data would not be ready. The converter will continue to operate during the read process.CS InputThe device will be enabled when CS is held low.RD InputThe 12-bit data bus lines are normally in a high impedance state. The output buffer is enabled when CS and RD are held low. The RD input is an edge-triggered input that acts as frame synchronization signal and output enable. A falling edge of the RD signal transfers data to the output buffer and data will be available on the serial output pin, SO. RD must be held low for t 9 before the data is valid on the outputs. After RD goes low, the serial data will be clocked out of the SO pin on the falling edges of the SCLK (after a minimum of t 10 ns): the MSB will be already available at the SO pin on the very first falling edge of the SCLK. Each other bit of the data word will be shifted out on the rising edge of SCLK and will be available at the SO pin on the falling edge of SCLK for the next 15 clock pulses.The high-to-low transition of RD must happen during the high time of the SCLK to avoid MSB being shifted on the first rising edge of the SCLK and lost. RD may rise high after the falling edge of the last bit transmitted. Subsequent negative edges greater than the defined word length will clock zeros from the data output if RD remains in a low state. If the user is reading data continuously, RD can be reapplied a minimum of t 5 ns after it is released.RDVEL InputRDVEL input is used to select between the angular position and velocity registers. RDVEL is held high for angular position and low for angular velocity. The RDVEL pin must be set (stable) at least t 4 ns before the RD pin is pulled low.。

Like the original SpectrAlert, the SpectrAlert ceiling mount series offer significant current draw reductions over other ceiling mount strobes and horn/strobes.Installation. SpectrAlert’s compact design also offers installation savings. Thestrobe and horn/strobe models mount to a 4˝×4˝×11⁄2˝ back box, and take up little room in the back box, making connections easier. And with SpectrAlert’s round shape, it is not necessary to align the back box with the room’s walls. SpectrAlert always lines up.Flexibility. SpectrAlert ceiling mount strobes and horn/strobes are available inseven different candelas, including 177 candela for sleeping areas. The horn/strobe’s tones are field-selectable through the use of a three position switch located on the back of the unit. Selections include electromechanical and 3 KHz tones, temporal and non-temporal patterns, and high and low volume.Aesthetics. SpectrAlert ceiling strobes and horn/strobes offer a design that is sensi-tive to the aesthetic demands of ceiling mount applications. The round shape main-tains a low profile appearance, similar to that of a smoke detector and provides clearly visible “FIRE” identification from all angles.Lower current drawAvailable in 15, 15/75, 30, 75, 95, 115,and 177 candelaHorn/strobe models include a threeposition switch for field-selecting horn tones:- Electromechanical/3KHz - Temporal/Non-temporal - High/Low dBA outputCeiling-specific shape, profile, and aestheticsSynchronizable with MDL Sync•Circuit ™moduleMounts to 4˝× 4˝× 11⁄2˝ back box Round shape offers greater placement flexibilityProduct OverviewSC241575W PC2475WS40117135-1209:20461-00-E 144-00-E元器件交易网General Specifications SpectrAlert Mounting DiagramsStrobe or Horn/Strobe with Mounting PlateStrobe or Horn/Strobe with Accessory Back Box SkirtStrobeStrobe shall be a System Sensor SpectrAlert Model _________ listed to UL 1971 and be approved for fire protective ser-vice where ceiling mount strobes are permitted.

All 12V products will be listed between 8 – 17.5V and all 24V products will be listed between 16 – 33V . Those devices are considered “regulat-ed”. Any product that does not operate within these ranges will be listed as a “special application” with its operating voltage specified on the device.Notes1. C urrent draw for strobe-only products is shown in Table 1-A.2. 24VDC 2-wire horn/strobe current draw is shown in Table 1-C.3.C urrent draw for other horn/strobe power supplies can be calculated by adding the strobe current in Table 1-A to the horn current in Table 1-B from the chosen settings.In May 2004 Underwriters Laboratories changed standard UL 1971 to require that operating current measuremments are made using RMS (root mean square) instead of peak or average values. RMS measurements more accurately predict the power consumption of a device since they take into account the entire current draw profile including surge, repetitive surge, and peak values. The published RMS cur-rent is the maximum operating current of that device within its operating voltage range. This current maximum may or may not occur at the endpoints of the voltage range.Similarly, UL tests the audibility of devices in accordance with UL 464 by measuring them across the operating volt-age range to determine the minimum sound pressure level produced at any particular setting.© 2005 System Sensor.

DESCRIPTION
The SC1205 is a cost effective Dual MOSFET Driver designed for switching High and Low side Power MOSFETs. Each driver is capable of driving a 3000pF load in 20ns rise/fall time and has a 20ns max propagation delay from input transition to the gate of the power FET’s. An internal Overlap Protection Circuit prevents shoot-through from Vin to GND in the main switching and synchronous MOSFET’s. The Overlap Protection circuit ensures the Bottom FET does not turn on until the Top FET source has reached a voltage low enough to prevent cross-conduction.
The high current drive capability (2A peak) allows fast switching, thus reducing switching losses at high (1MHz) PWM frequencies. The high voltage CMOS process allows operation from 5-25 Volts at top MOSFET drain, thus making SC1205 suitable for battery powered applications. Connecting Enable pin (EN) to logic low shuts down both drives and reduces operating current to less than 10uA.
