NCP1083Integrated High PowerPoE-PD Interface & DC-DC Converter Controller with9 V Auxiliary Supply Support IntroductionThe NCP1083 is a member of ON Semiconductor’s high power HIPO t Power over Ethernet Powered Device (PoE−PD) product family and represents a robust, flexible and highly integrated solution targeting demanding medium and high power Ethernet applications. It combines in a single unit an enhanced PoE−PD interface supporting the IEEE 802.3af and the upcoming draft IEEE 802.3at (D3.0) standard and a flexible and configurable DC−DC converter controller. The NCP1083’s exceptional capabilities enable applications to smoothly transition from non−PoE to PoE enabled networks by also supporting power from auxiliary sources such as AC power adapters and battery supplies, eliminating the need for a second switching power supply.ON Semiconductor’s unique manufacturing process and design enhancements allow the NCP1083 to deliver up to 25.5 W for the draft IEEE 802.3at (D3.0) standard and up to 40 W for proprietary high power PoE applications. The NCP1083 enables the draft IEEE 802.3at (D3.0) and implements a two event physical layer classification. Additional proprietary classification procedures support high power power sourcing equipment (PSE) on the market. The unique high power features leverage the significant cost advantages of PoE−enabled systems to a much broader spectrum of products in emerging markets such as industrial ethernet devices, PTZ and Dome IP cameras, RFID readers, MIMO WLAN access points, high−end V oIPphones, notebooks, etc.The integrated current mode DC−DC controller facilitates isolated and non−isolated fly−back, forward and buck converter topologies. It has all the features necessary for a flexible, robust and highly efficient design including programmable switching frequency, duty cycle up to 80 percent, slope compensation, and soft start−up.The NCP1083 is fabricated in a robust high voltage process and integrates a rugged vertical N−channel DMOS with a low loss current sense technique suitable for the most demanding environments and capable of withstanding harsh environments such as hot swap and cable ESD events. The NCP1083 complements ON Semiconductor’s ASSP portfolio in industrial devices and can be combined with stepper motor drivers, CAN bus drivers and other high−voltage interfacing devices to offer complete solutions to the industrial and security market.FeaturesPowered Device Interface•Flexible Auxiliary Power Supply Support•9 V Front, Rear and Direct Auxiliary Supply Connections •Supporting the IEEE 802.3af and the Upcoming Draft IEEE 802.3at (D3.0) Standard•Supports Draft IEEE 802.3at (D3.0) Two Event Layer 1 Classification•High Power Layer 1 Classification Indicator •Extended Power Ranges up to 40 W •Programmable Classification Current •Adjustable Under V oltage Lock Out •Programmable Inrush Current Limit •Programmable Operational Current Limit up to1100mA for Extended Power Ranges•Over−temperature Protection•Industrial Temperature Range −40°C to 85°C with Full Operation up to 150°C Junction Temperature•0.6 W Hot−Swap Pass−switch with Low Loss Current Sense Technique•Vertical N−channel DMOS Pass−switch Offers the Robustness of Discrete MOSFETs with Integrated Temperature ControlNCP1083 = Specific Device CodeXXXX= Date CodeY= Assembly LocationZZ= Traceability CodeTSSOP−20 EPDE SUFFIXCASE 948ABSee detailed ordering and shipping information in the packagedimensions section on page 2 of this data sheet.ORDERING INFORMATIONDC −DC Converter Controller•Current Mode Control•Supports Isolated and Non −isolated DC −DC Converter Applications•Internal V oltage Regulators•Wide Duty Cycle Range with Internal Slope Compensation Circuitry•Programmable Oscillator Frequency •Programmable Soft −start Time(Top View)PIN DIAGRAMExposed Pad1SS FB COMP VDDL VDDH GATE ARTNnCLASS_AT CS OSCVPORTP CLASS UVLO INRUSH ILIM1VPORTN1RTN VPORTN2AUX TESTOrdering InformationPart NumberPackage Shipping Configuration †Temperature Range NCP1083DEG TSSOP −20 EP (Pb −Free)74 units / Tube −40°C to 85°C NCP1083DER2GTSSOP −20 EP (Pb −Free)2500 / Tape & Reel−40°C to 85°C†For information on tape and reel specifications, including part orientation and tape sizes, please refer to our Tape and Reel Packaging Specification Brochure, BRD8011/D.VPORTN1,2VPORTPINRUSH VDDHnCLASS_AT VDDLRTNARTNSSFB COMP CSGATEOSC Figure 1.

Non−Isolated Fly−back with Extra Winding and Rear Auxiliary SupplyFigure 4 shows the same non−isolated fly−back configuration as Figure 3, but adds a 12V auxiliary bias winding on the transformer to provide power to the NCP1083 DC−DC controller via its VDDH pin. This topology shuts off the current flowing from VPORTP to VDDH and therefore reduces the internal power dissipation of the PD, resulting in higher overall power efficiency.Figure 5. Non−Isolated Forward Converter with Rear Auxiliary SupplyFigure 5 shows the NCP1083 used in a non−isolated forward topology.High Power ConsiderationsThe NCP1083 is designed to implement various configurations of high−power PoE systems including those based on the developing IEEE 802.3at standard. High power operation can be enabled by a Dual Event Layer 1 classification or a Single Event Layer 1 classification combined with a Layer 2 high power classification. The NCP1083 also supports proprietary designs capable of delivering 25 W to 40 W to the load in two−pair configurations. A separate application note describes these implementations (“NCP1081 High Power PoE Applications”).Table 1. Pin DescriptionsName Pin No.Type DescriptionVPORTP1Supply Positive input power.

In orderto give more flexibility to the user and also to keep controlof the power dissipation in the NCP1083, both current limitsare configurable. The device enters operation once its programmable Vuvlo_on threshold is reached, andoperation ceases when the supplied voltage falls below theVuvlo_off threshold. Sufficient hysteresis and Uvlo filtertime are provided to avoid false power on/off cycles due totransient voltage drops on the cable.DetectionDuring the detection phase, the incremental equivalentresistance seen by the PSE through the cable must be in theIEEE 802.3af standard specification range (23.75k W to26.25k W) for a PSE voltage from 2.7 V to 10.1 V. In orderto compensate for the non-linear effect of the diode bridgeand satisfy the specification at low PSE voltage, theNCP1083 presents suitable impedance in parallel with the25.5k W Rdet external resistor. For some types of diodes(especially Schottky diodes), it may be necessary to adjustthis external resistor.When the Detection_Off level is detected (typically11.5V) on VPORTP, the NCP1083 turns on its internal3.3V regulator and biasing circuitry in anticipation of the classification phase as the next step.ClassificationOnce the PSE device has detected the PD device, the classification process begins. The NCP1083 is fully capableof responding and completing all classification handshakingprocedures as described next.Classification Current Source GenerationIn classification, the PD regulates a constant currentsource that is set by the external resistor RCLASS value onthe CLASS pin. Figure 8 shows the schematic overview ofthe classification block. The current source is defined as:I class+V bgR class,(where V bg is1.2V)Figure 8. Classification Block DiagramThe NCP1083 can handle all defined types of classification, IEEE 802.3af, draft IEEE 802.3at (D3.0) and proprietary classification.In the IEEE 802.3af standard the classification is performed with a Single Event Layer 1 classification. Depending on the current level set during that single event the power level is determined. The current draft IEEE 802.3at (D3.0) allows two ways of classification which can also be combined. These two approaches enable higher power applications through a variety of PSE equipment. For power injectors and midspans a pure physical hardware handshake is introduced called Two Event Layer 1 classification. This approach allows equipment that has no data link between PSE and PD to classify as high power. Since switches can establish a data link between PSE and PD, a software handshake is possible. This type of handshake is called Layer 2 classification (or Data Link Layer classification). It has the main advantage of having a finer power resolution and the ability for the PSE and PD to participate in dynamic power allocation.Table 4. Single and Dual Event Classification Standard Layer Handshake802.3af1Single event physical classification802.3at1Two event physical classification802.3at2Data-link (IP) communication classi-ficationOne Event Layer 1 ClassificationAn IEEE 802.3af compliant PSE performs only One Event Layer 1 classification event by increasing the line voltage into the classification range only once.Two Event Layer 1 ClassificationA draft IEEE 802.3at (D3.0) compliant PSE using this physical classification performs two classification events and looks for the appropriate response from the PD to check if the PD is draft IEEE 802.3at (D3.0) compatible.The PSE will generate the sequence described in Figure8. During the first classification finger, the PSE will measure the classification current which should be 40 mA if the PD is at compliant. If this is the case, the PSE will exit the classification range and will force the line voltage into the Mark Event range. Within this range, the PSE may check the non-valid input signature presented by the PD (using the two point measurement defined in the IEEE 802.3af standard). Then the PSE will repeat the same sequence with the second classification finger. A PD which has detected the sequence “Finger + Mark + Finger + Mark” knows the PSE is draft IEEE 802.3at (D3.0) compliant, meaning the PSE will deliver more current on the port. (Note that a PSE draft IEEE 802.3at (D3.0) compliant may apply more than two fingers, but the final result will be the same as two fingers).Class rangeMark Range Reset RangePSE identified by default as type 1 PSE (af)PSE Type identification:Figure 9. Hardware Physical Classification Event SequencenCLASS_AT IndicatorThe nCLASS_AT active low open drain output pin can be used to notify to the microprocessor of the powered device that the PSE performed a one or two event hardware classification. If a two event hardware classification has occured and once the PD application is supplied power by the NCP1083 DC-DC converter, the nCLASS_AT pin will be pulled down to ARTN by the internal low voltage NMOS switch (ARTN is the ground connection of the DC-DCconverter). Otherwise, nCLASS_AT will be disabled and will be pulled up to VDDL (3.3 V typ) via an internal current source (20 m A typ) and via the external pull-up resistor.The following scheme illustrates how the nCLASS_AT pin may be configured with the processor of the powered device. An opto-coupler is used to guarantee full isolation between the Ethernet cable and the application.Figure 10. Isolated nClass_AT Communication with the Powered Device ApplicationAs soon as the application is powered by the DC-DC converter and completes initialization, the microprocessor should check if the NCP1083 detected a two event hardware classification by reading its digital input (pin IN1 in this example). If pin IN1 is low, the application knows power is supplied by a draft IEEE 802.3at (D3.0) compliant PSE, andcan deliver power up to the level specified by the draft IEEE 802.3at (D3.0) standard.Otherwise the application will have to perform a Layer 2classification with the PSE.

Load and line regulation are measured at a constant junction temperature by low duty cycle pulse testing.Note 3: Line and load regulation are guaranteed up to the maximum power dissapation (60W for the LT1083, 45W for the LT1084 (K, P), 30W for the LT1084 (T) and 30W for the LT1085). Power dissipation is determined by the input/output differential and the output current. Guaranteed maximum power dissipation will not be available over the full input/output voltage range.Note 4: I FULL LOAD is defined in the current limit curves. The I FULLLOAD curve is defined as the minimum value of current limit as a function of input-to-output voltage. Note that the 60W power dissipation for theLT1083 (45W for the LT1084 (K, P), 30W for the LT1084 (T), 30W for the LT1085) is only achievable over a limited range of input-to-output voltage. Note 5: Dropout voltage is specified over the full output current range of the device. Test points and limits are shown on the Dropout Voltage curve.Note 6: For LT1083 I FULL LOAD is 5A for –55°C ≤ T J < –40°C and 7.5A for T J≥ –40°C.Note 7: 1.7V ≤ (V IN – V OUT) ≤ 25V for LT1084 at –55°C ≤ T J≤–40°C. Note 8: Dropout is 1.7V maximum for LT1084 at –55°C ≤ T J≤ –40°C.The ● denotes the specifications which apply over the full operating temperature range, otherwise specifications are at T A = 25°C.108345feAPPLICATIO S I FOR ATIO W UU U Connected as shown, R P is not multiplied by the divider ratio. R P is about 0.004Ω per foot using 16-gauge wire.This translates to 4mV/ft at 1A load current, so it is important to keep the positive lead between regulator and load as short as possible and use large wire or PC board traces.Thermal ConsiderationsThe LT1083 series of regulators have internal power and thermal limiting circuitry designed to protect the device under overload conditions. For continuous normal load conditions however, maximum junction temperature rat-ings must not be exceeded. It is important to give careful consideration to all sources of thermal resistance from junction to ambient. This includes junction-to-case, case-to-heat sink interface, and heat sink resistance itself. New thermal resistance specifications have been developed to more accurately reflect device temperature and ensure safe operating temperatures. The data section for these new regulators provides a separate thermal resistance and maximum junction temperature for both the Control Sec-tion and the Power Transistor . Previous regulators, with a single junction-to-case thermal resistance specification,used an average of the two values provided here and therefore could allow excessive junction temperatures under certain conditions of ambient temperature and heat sink resistance. To avoid this possibility, calculations should be made for both sections to ensure that both thermal limits are met.Junction-to-case thermal resistance is specified from the IC junction to the bottom of the case directly below the die.This is the lowest resistance path for heat flow. Proper mounting is required to ensure the best possible thermal flow from this area of the package to the heat sink. Thermalcompound at the case-to-heat sink interface is strongly recommended. If the case of the device must be electri-cally isolated, a thermally conductive spacer can be used,as long as its added contribution to thermal resistance is considered. Note that the case of all devices in this series is electrically connected to the output.For example, using an LT1083CK (TO-3, Commercial) and assuming:V IN (max continuous) = 9V, V OUT = 5V, I OUT = 6A,T A = 75°C, θHEAT SINK = 1°C/W,θCASE-TO-HEAT SINK = 0.2°C/W for K package with thermal compound.Power dissipation under these conditions is equal to:P D = (V IN – V OUT )(I OUT ) = 24W Junction temperature will be equal to:T J = T A + P D (θHEAT SINK + θCASE-TO-HEAT SINK + θJC )For the Control Section:T J = 75°C + 24W (1°C/W + 0.2°C/W + 0.6°C/W) = 118°C 118°C < 125°C = T JMAX (Control Section Commercial Range)For the Power Transistor:T J = 75°C + 24W (1°C/W + 0.2°C/W + 1.6°C/W) = 142°C 142°C < 150°C = T JMAX (Power Transistor Commercial Range)In both cases the junction temperature is below the maximum rating for the respective sections, ensuring reliable operation.11121314Information furnished by Linear Technology Corporation is believed to be accurate and reliable.

Easy Start364 (3 ton) Soft Starter368 (6 ton) Soft StarterInstallation ManualMicro Air Corporation Phone (609) 259-2636 124 Route 526. Allentown NJ 08501 Fax (609) 259-6601Retrofit Instructions1.Read and understand these instructions completely before proceeding.2.Improper wiring can result in damage to EasyStart or connected components including but not limited towiring, compressors, and capacitors. Micro Air Corp is not responsible for damages to any of theaforementioned equipment caused by improper wiring.3.Turn off the breaker for the compressor’s electrical system.4.Consult the manufacture’s installation manual and wiring diagram for the identification of the following:a.Start capacitor (typically in a plastic can), start relay, or compressor start device. Note that thesedevices may NOT be installed on some systems.b.Run capacitor (typically in a metal can). Most have 2, multi-point terminal connections (orclusters). Some have 3 terminal connections.c.Control board switched-L1 output or main contactor compressor L1 output connecting to thecompressor common terminal (C) wire. Note some systems utilize a contactor to switch power tothe compressor, other use a power relay integrated into the main control board.5.If the system utilizes a start capacitor with a start relay, or a start assist device, disconnect all the wiringconnected to the start capacitor or the start assist and remove them from the electric box. Be aware thatsome connections to the compressor (e.g. compressor common L1 and compressor Run L2) may havejunction connections at terminals of the start relay. Therefore, it is best to NOT remove the start relayunless you are able to trace out these wiring junctions and splice them. Disconnecting and removing only the start capacitor from a system with a start cap and start relay will effectively disable the start relay, thus eliminating the need for it being removed.6.Locate the compressor run capacitor. Locate the wire connected from the run capacitor to the compressorrun winding terminal (R), and disconnect it from the run capacitor. Connect (splice) the brown wire from EasyStart to the disconnected wire.7.Connect the white wire from EasyStart to the same terminal of the run capacitor from which youdisconnected the (white) run winding (R) wire in step 6 above.8.Connect the orange wire from EasyStart to the terminal on the run capacitor that connects to thecompressor start winding terminal (S). If the run capacitor is a dual, compressor/fan type, make sure tochoose the correct capacitor terminal, typically labeled “COMP”, “C”, Herm, or “H”.9.Connect the black wire from EasyStart to the switched-L1 connection emanating from the main controlboard or main contactor that typically has a black or purple wire that connects to the compressor common(C) terminal wire.10.Wiring is now complete. Remove any remaining unused or disconnected wires and close all open electricalboxes and panels.11.Securely mount the EasyStart using the four holes provided on the mounting flange, locating it close to theoriginal system electric box (limited by wire harness length).12.Turn on the system circuit breaker using shore power. Start a heating or cooling cycle with the thermostat.13.EasyStart will now learn the characteristics of the compressor for the next five starts. This operation will bedone during normal operation and does not require any intervention or special actions. Once the learning process is completed, the EasyStart can be operated on either shore or generator power. During the learning starts, be sure to allow enough off time between starts for pressures to equalize. Equalization occurs in most systems within five minutes so we advise waiting at least five minutes between starts.IMPORTANT INSTALLATION NOTE FOR CRUISAIR® MARINE CUSTOMERS ONLY: When installing EasyStart into 230V SMX control applications that use the triac to switch power to the compressor, it is necessary to replace the triac with a relay. If the triac is not replaced, the pump relay triggers may suffer damage and ultimately fail. Please notr that this is not required for 115V SMX applications and the triac is still safe to use. See the Microair Webstore or contact Microair for details on the appropriate relay.Example EasyStart Installation Wiring Diagram:Jumper Usage:A six pin diagnostic header is located inside the EasyStart box. Most installations will not need to access this header.Jumpers may be placed on JP1 for certain special functions. Place jumpers only asshown below.Normal:Most operation should be done without a jumper installed on JP1 or with the jumperinstalled across pins 3 and 4 as shown.Default:A compressor may be operated with a factory defined start characteristic. This maynot be the optimal start for the connected compressor and is generally used for factorydiagnostics. No optimization is done with this setting.Relearn:If a compressor, start capacitor, or run capacitor is replaced, place a jumper onpins 4 and 6 as shown. Cycle power on then off again and replace the jumper in the “Normal”position. Follow step 13 of the retrofit instructions to complete the relearn process.Disable:This setting disables the microprocessor on the board so no operation can occur. Anti-Short Cycle Timer:EasyStart models incorporate a timer that prevents immediate restarts.This feature was added to prevent overheating of the start capacitor and reducefaults due to un-equalized pressures in the system. Restart will take up to 5minutes if power is removed then reapplied.Later models include a wire jumper JP2 (see picture on right) that canbe cut to eliminate this feature. System controls must be sufficient to prevent short cycling if this jumper is cut. Warning: Starts must be limited to 1 start every 5 minutes with pressures equalized if JP2 is cut.EasyStart Troubleshooting:Wiring Evaluation:A ll start components from the original installation are removed including PTC’s and startcapacitors.The Brown wire from EasyStart connects directly to the compressor run winding.The Black wire from EasyStart is spliced to the thermostat relay feeding the compressor overloadprotector on the compressor common terminal.The Orange wire from EasyStart is connected to the compressor run capacitor on the same side asthe compressor start winding.The White wire from EasyStart is connected to the AC-L2 or AC-N side of the compressor runcapacitor.Trouble Lights:Three diagnostic lights are provided inside the EasyStart box on the printed circuit board. These lights are labeled in white silkscreened letters next to the light. When a fault is detected, EasyStart willilluminate one or more lights to indicate which fault occurred. All faults except over current will reset after3 minutes. Over current is reset by removing power from EasyStart and reapplying power. Users will notnormally need to view these lights. The chard below defines the lights that are turned on for each fault.Fuses:Protection fuses are installed in the start circuit to prevent damage due to miswiring or start capacitorfailure. If this fuse fails in normal operation, there is most likely a problem with the start capacitor which should be replaced along with the fuse.364 (3 ton)1.Revision H and earlier boards: These boards incorporate a non-replaceable fuse inthe start circuit. These units must be returned to Microair for repair.2.Revision I and above boards: These boards incorporate a replaceable 15A 250Vrated, slow blow, 5mm x 20mm glass fuse.368 (6 ton)1.Revision E and earlier boards: These boards incorporate a non-replaceable fuse inthe start circuit. These units must be returned to Microair for repair.2.Revision F and above boards: These boards incorporate a replaceable 30A 250VACrated 3AB, 3AG, ¼” x 1 ¼” (6.35mm x 31.75mm) slow blow ceramic fuse.FAQ:What is re-learning?The re-learning process simply clears the EasyStart memory and returns it to as shipped condition. EasyStart should be re-learned whenever a compressor is changed or if pressures were not allowed to equalize during the learning process.To re-learn EasyStart, remove power and open the EasyStart box. Locate the 6 pin header shown in the jumper usage section of this manual and place the shorting jumper over pins 4 and 6 as shown. Start a cycle with your thermostat with the compressor powered from AC mains and allow EasyStart to start the compressor. Remove power once the compressor starts and replace the jumper to the stored position over pins 3 and 4. Replace the cover on EasyStart and complete at least 4 additional starts. Be sure to allow time for pressures to equalize between starts, usually 3 to 5 minutes.Be sure to remove the jumper from pins 4 and 6 and replace it to pins 3 and 4 immediately after the FIRST start and after power is removed.I connected everything and it just won’t start. What do I do now?First, do the wiring evaluation in this section. Wiring should be exactly as shown in the sample diagram with no left over start components. If there are any questions about wiring your unit, you can send a wiring diagram for your compressor to **************** along with your question.Be sure you are only using regular AC line power and not a generator or inverter for the first five starts. The first starts on EasyStart are usually higher than the final start and can overload marginal supplies and prevent EasyStart from learning the best start for your compressor.Check for any trouble lights. If any are illuminated, identify the reason EasyStart is not starting your compressor. Most times trouble lights point to a problem with the wiring.What does a “S talled” indication from EasyStart mean?Stalled means EasyStart is not seeing the condition where it can declare that the compressor is running and connect the compressor directly. The first thing to do is the wiring evaluation above.Stalled can also be caused by an improperly sized or bad start capacitor. 3T systems with 220 volt 12K BTU and smaller compressors may require smaller value start capacitors. Contact Microair prior to purchase to determine requirements for these systems.What d oes “Power Interruption” mean?Power was lost for several AC cycles of power and EasyStart shut down. Compressors will stall after only a few lost cycles creating a huge load when power is restored. EasyStart prevents this excessive load by preventing operation for 3 minutes. EasyStart will restart the compressor following this delay.We have found that some power conditioning equipment uses relays to switch taps on a transformer may switch too slowly to properly run a compressor.What does “Start winding not detected-EasyStart is miswired” mean?One of the following:The orange wire is not connected to the start winding.The Compressor Start winding is open.Line L2 is connected to the compressor start winding.COPYRIGHT© 2017 Micro Air Corporation, All Rights ReservedNo part of this publication may be reproduced, translated, stored in a retrieval system, or transmitted in any form or by any means electronic, mechanical, photocopying, recording or otherwise without prior written consent by Micro Air Corporation.Every precaution has been taken in the preparation of this manual to insure its accuracy.

NCP1083WIRGEVBNCP1083WIRGEVBCompact, High Efficiency,30 W Reference Platform,Supporting Wide Auxiliary Input Voltage, with theNCP1083 Evaluation Board User's ManualBoard DetailsThe NCP1083WIRGEVB implements a PoE module DC/DC converter that converts the higher voltage one the Ethernet cable to a lower voltage (12V) with power levels up to 30W. Detection, classification and power up sequence is implemented according to IEEE802.3at (D4). The board also supports getting its power from and auxiliary input, in case PoE network is not available. Auxiliary input voltage may be as low as 9V . The isolated flyback DC/DC converter design is optimized to support a very wide input voltage range (9V to 57V) without compromising the overall efficiency.WarningsClose to the switching MOSFET voltages on the board may exceed 200V (@250kHz). Temperature of board and its components may exceed 85︒C during normal operation.The Evaluation board was designed to operate correctly under these conditions.The input voltage should never exceed 57V nor should the evaluation board be loaded for long duration with loads higher than the specified 30W. Exceeding the specified input and output values could permanently damage theboard.Figure 1. Front Side of EVBFigure 2. Back Side of EVBTable 1.

做个电源，LT1083芯片，0~30V可调线形电源

做个电源，LT1083芯⽚，0~30V可调线形电源这次制作，⽤到的元件，除了数字电压表头和数字电流表头是买的，其他都是⽤的拆机元件外壳⽤了⼀个报废的电脑电源外壳，变压器也是旧的，不过功率够⼤主要调压芯⽚⽤了1083三端调压，最⼤输出到7.5A，不过平常⽤不到那么⼤的电流⽬前，还在制作外壳，机壳内部布局阶段这个⼤家伙，就是这次⽤的变压器了输出电压1083加上散热⽚的样⼦，其他部分元件还没有进⾏焊接整流桥这个三段开关，⽤来选择变压器输出电压先⽐划⼀下这个⼤家伙，放在机壳内部的样⼦制作过程也是没有什么详细计划，因为机壳就那么⼩，需要把不少东西塞进去，只能是慢慢摸索，交流电电源输⼊部分处理⼀下，加了⼀个保险管卡⼦把电源风扇安装在外部，保护⽹也在外边装进去变压器，已经占去⼀多半的空间了，其他元件，就是要好好找⽣存空间了原来板⼦上有个电线插头，可以利⽤⼀下处理以后的效果找的⼩散热⽚，给整流桥和7807稳压器散热，7V电压⽤来驱动风扇，和给两个数字表头供电安装的⼤致效果，开始把7V电压完全独⽴了，独⽴的整流桥，独⽴的7807稳压芯⽚，结果发现，7V电压和主电压的负极之间还有电压差，如果两个负极直接相连，还有微弱电流，最后还是放弃7V独⽴整流了，直接冲主变压器取电给1083主调压芯⽚，增加⼀下散热⽚这⾥⽤的⽀撑柱⼦，是电脑主板上拆的电压调节开关的位置找个⽩塑料遮挡⼀下，稍微美观了⼀些找了个⼩电位器，作为电压微调就地取材，找了⼀个固定的位置内部空间狭⼩，安排散热⽚，电路板，要费不少时间最后感觉这个位置，挺合适的散热⽚通过铁柱⼦和外壳固定另外还找了⼀个开关，安装在前⾯板上，后⾯还有⼀个开关，不过不够⽅便最后的效果内部接线测试过程中，发现7V供电的新⽚，⽐较热，原因是当使⽤⾼电压档位的时候，很⼤的电压加在稳压芯⽚7807上⾯，造成功耗过⼤，考虑给7807芯⽚多增加⼀点散热⽚，由于空间限制，在电脑主板上找了⼀个北桥散热⽚，厚度刚好，就是有点宽了，要裁下⼀块要增加的散热⽚稳压芯⽚，移动到旁边，给散热⽚腾格地⽅裁开了打孔，进⾏安装试验正式安装前，加上导热胶安装以后的效果厚度刚好不影响外壳最后进⾏电压调整，调节可变电阻，让电压变化范围正好落在30V以内，因为我这个4位的电压表，最⾼显⽰30.00V,超过以后显⽰1,变压器的输出能⼒35V，实际上很少⽤到30V以上的电压最⾼电压30V最低电压0.13V, 应该是0.00V就完美了，可能是我的元件问题，稍有差别精确调出来12.00V，纹丝不动⾃制电源和买来的合⼀个影LT1083稳压电源制作好了。

BLDC MOTOR CONSTRUCTION
This algorithm has been tested on these motors:
• 4-pole, 12V, 10A fan motor with a maximum speed of 29,000 RPM
The arrows in the winding diagram show the direction current flows through the motor windings in each of the six steps. The graph shows the potential applied at each lead of the motor during the six steps. Sequencing through these six steps moves the motor one electrical revolution.
BLDC motors are used in a variety of applications. The algorithm described in this application note targets BLDC motors that operate in the 40k to 100k electrical RPM range. Some BLDC motor applications that run in this RPM range are model RC motors, fans, hard drives, air pumps and dental drills.
The algorithm described in this application note can be implemented on two Microchip development board platforms:
• PICDEM™ MC LV Development Board
• dsPICDEM™ MC1 Development Board
The motor turns when a current is passed through motor windings, as shown by the arrow (1) in Figure 4. In this example, a positive potential is applied to the red (R) lead, and a negative potential is applied to the green (G) lead. Charging the motor windings in this manner generates the magnetic field in the stator, noted by the N and S designations. The rotor then turns so that the north pole in the rotor aligns with the magnetic south generated in the stator. Likewise, the south pole in the rotor aligns with the magnetic north generated in the stator.

Sensorless BLDC Control With Back-EMF Filtering
Author: Reston Condit Microchip Technology Inc.
INTRODUCTION
This application note describes a sensorless brushless DC (BLDC) motor control algorithm, implemented using the dsPIC® digital signal controller (DSC). The algorithm works by digitally filtering the back-Electromotive Force (back-EMF) on each phase of the motor and determining when to commutate the motor windings based on the filtered back-EMF signals. This control technique precludes the need for discrete, low-pass filtering hardware and off-chip comparators.

Current flow through windings generates magnetic field (designated by N and S) in the stator, causing the north and south poles of the rotor to align with the south and north poles, respectively, of the stator.
In the Y-connected BLDC motor (see Figure 3), the motor has three leads, each connected to a winding. Each winding (or series of windings) is connected to a common point shared by all three windings, as shown in the upper portion of Figure 3. The basic construction of a simple BLDC motor is shown in the lower portion of Figure 3.

The outer layer of the motor, which houses the motor windings, is the stator. The inner part of the motor is the rotor. The rotor consists of opposing magnetic poles located around the circumference of the motor. Figure 4 shows a rotor with only two poles, north and south. In reality, most motors have more than one set of magnetic poles on the rotor.
