华为IPD流程指南第3.0版
前言华为已经开始了业务变革的旅程。
华为在变革之路上迈出的重要第一步是决定通过一种经过验证的、贯穿一致的规范方法来管理产品开发工作。
华为的选择是集成产品开发（IPD）流程。
千里之行，始于足下。
已经迈出关键第一步的华为，目前正沿着IPD 之路前进。
并非所有的旅程都是一帆风顺的，并非所有的旅程都是毫无险阻、无所畏惧的，并非所有的旅程都是毫不犹豫、一直前进的。
不过，只要走了，所有的旅行都能使人们更好地加深认识，增长经验并取得更大的成就。
现在我们已经走到了IPD之旅的IPD流程版。
我们已经取得了不小的成绩，但是仍有更多的事情要我们来完成。
我们已经转变了许多，但是有更多的地方需要改变。
我们已经学了不少，但是学无止境。
在IPD之旅的前进道路上，我们必须时刻注意前方的道路，知道为了使我们的旅行成功，需要做哪些工作。
要想使IPD之旅获得成功，我们要继续力排众议，消除大家对IPD的疑惑。
我们要各尽其力，平和地说服我们身边对IPD 有疑惑的人，改变他们的看法，并将这些案例与其他人共享，给他们加油鼓劲。
下面提供了一些指导，可以使你在充满险阻的变革旅程中保持坚定的信念，重点关注相应的领域，保持成功的势头：疑虑：IPD 不够灵活。
事实：IPD非常灵活。
IPD流程是一种改进运作效果的平衡方法。
事实上，IPD流程是非常灵活的，可以适合于所有的软硬件开发项目。
IPD流程实际上并不是要求所有项目都逐一地执行所有活动，而是可以、也应该根据项目的实际情况对活动进行一定的调整。
针对小项目更加明确的规范已经制定出来了。
不过，对IPD无限灵活性的探索能力与我们的知识、对IPD的理解以及实际的经验和实践是分不开的。
疑虑：走IPD流程用的时间太长了。
事实：IPD会将产品上市时间提前。
不过，要实现IPD本身的这些好处需要华为停用或者进一步重新设计自己的老流程，而且在向未来前进的过程中，不要依然留恋过去。
如果仅仅是简单地加入新流程和作法，但仍然按照老流程和老作法进行运作，最终结果只有失败。
ST - III系列电源用户手册说明书
ST - III Series POWER SUPPLIESUSER MANUALIntroductionThese instructions detail the installation and operation requirements for the ST20-III & ST35-III power supplies. These have been designed for operation in RV’s providing a DC power system, with optional battery back up.The units operate from 240Vac and provide an isolated 13.65Vdc output at 20A and 35A respectively for powering the load and charging of batteries. All the necessary protection and operating features for the load and batteries are provided. An optional DC input is also provided to enable charging of batteries and powering of the load from an external +13.8V DC power source. The units are fully enclosed ready for direct wall mounting. All connections are at the rear of unit providing convenient wiring and installation. User access to all load and battery fusing has been provided from the front of the unit.OperationSafety: Refer to the installation section before operating. Correct installation is the most critical factor in ensuring the safe use of the power supply. If every consideration of these instructions has been satisfied the power supply will be safe to operate.If the AC supply cord is damaged it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid hazard.The unit is rated to charge a single 12V (up to 6 cells) lead acid battery at 100Ahr Capacity. Functional Diagram:AC/DC Power Supply: This provides an isolated 13.65Vdc output for powering of the load and float charging of the battery. Battery current is sensed and monitored by the power supply to ensure that the maximum charging current is not exceeded.Battery Features: The power supply provides full battery management as per the following.The power supply is a four stage battery charger with Boost (VBoost = 14.05V), Float (VFloat = 13.65V), Store (VStore = 13.25V) and Trickle charge modes to ensure long battery life.Battery Charging current is limited to a maximum of 10A (ST20-II) and 15A (ST35-II). This provides optimum life for the batteries.To charge at the maximum battery charge current above, ensure the load current plus battery current is equal or less than the maximum output current. The charging current will be reduced in situations where the difference between the rated output current and the load current (the available charging current), is less than the maximum charging current.Also note that the battery current sense is provided in the “Batt +ve” battery output. For this feature to work, the load “+ve” and battery “Batt +ve” should not be cross connected. (Appliances should not be connected to both the “Batt +ve” and “+ve” terminals of the power supply. Appliances should be connected to the “+ve” and “-ve” load terminals).Low Voltage Disconnection of the batteries is provided to prevent deep discharge of the battery. Automatic reconnection occurs when battery voltage recovers.Battery Current Drain is less than 2mA.Trickle Charge to the battery is always present. When the battery voltage is below the LVD (Low voltage disconnect) re-connect voltage (<10V and the mains power or auxiliary power is available, the battery will be charging at 0.8A. When the battery voltage is sufficient (>10.5V for first power up, 11.5V and 11.7V for subsequent reconnection with and without mains respectively) the LVD will connect the battery and allow float charging at 10A/15A (ST20-II/ST35-II). The Trickle Charge feature is provided to allow “very” flat batteries to be charged at a rate, which will extend their life.Remote Battery Isolate Switch: The ST-III series power supplies allow for connection to a remotely positioned switch that provides a manual disconnection of the battery from the loads and the main charger. When the switch contacts are closed, the battery will be isolated from the loads. NOTE: When the battery is isolated from the loads using the battery isolate switch it will NOT charge at the 10/15 A rate even if the mains is connected to the power supply. In this condition it will ONLY charge at the Trickle charge rate.Front Panel Indicators: The ST-III series power supplies have 3 indicators visible on the front fascia.Mains(GREEN) – is illuminated when mains power is present.Battery(ORANGE) – is illuminated when the battery is connected to the loads.Fault(RED) – is illuminated when there is a fault with the power supply.Battery fuse Blown1Battery connected reverse polarity2Shut down condition (UV and OT)3Main PCB micro controller malfunction4Notes1.Flashing 1s ON, 1s OFF.2.Solid ON.3.Flashing 1s ON, 1s OFF, with no battery connected the power supply may be in hiccupmode which will cause the indication to flash with random duty cycle and frequency.4.Fault Led= Solid On, All other leds = OFF, irrespective of actual mains or LVD status. Auxiliary Power Input: The power supply terminal “Aux In +VE” provides an alternative option for powering of the load and float charging of the batteries when mains voltages are not present. This input is to be powered by a suitable +12V system. (i.e. CAR). The voltage of the auxiliary power source should not exceed 14.8 volts.When operating via the external input, current and voltage control for the battery must be provided from the external source. The ST20-II/35-II does not provide battery current limit or voltage control when operating in this configuration. Trickle Charge is still functional when powered through “Aux In +VE” terminal of power supply.Suitable fuse protection must be provided for this input. A fuse rating not exceeding 20 Amps for ST20-II and 30 Amps for ST35-II must be used.Solar power should be connected directly across the battery terminals with a voltage regulator in series. A solar panel voltage regulator with maximum output voltage not exceeding 14.8 volts must be used at all times. Failure to use a voltage regulator may result in power supply damage. Generator 12 volt outputs should not be connected across battery terminal whilst battery is connected to power supply or connected to the “Aux In +VE” terminal of power supply. Serious power supply damage or internal explosion may occur. If a flat 12 volt battery has to be charged using the generators 12 volt output, it should first be disconnected from the power supply. Once battery has being charged it can then be reconnected to power supply.Power supply unit should only be powered from either 240VAC mains or Auxiliary Power (Auxiliary Power also includes solar power) but not both. Failure to do so may result in damage to power supply.Protection: the power supply provides automatic protection for overload including short circuit, over-voltage, over-temperature and reverse connected battery. In such instances the Fault indicator will illuminate and the power supply will shut down. It will attempt to automatically restart every 5 seconds until such case that the fault is removed.Fusing: Each load circuit and the battery have been fused to provide fault protection and discrimination. Refer to servicing section for maximum fuse ratings.InstallationHost Equipment: The host equipment must ensure that access to the unit (other than the front panel) by the user is prevented.Personnel: Installation is to be carried out only by suitably qualified personnel.Ventilation: Provide a minimum of 80mm clearance above, below and behind the unit. The final enclosure must also provide adequate ventilation to the outside world (or larger internal cavity) to prevent the build up of hot air. Failure to provide adequate ventilation will mean the unit may prematurely trip thermal shut-down. A minimum ventilation of 20,000mm2 to the outside world must be provided.Mechanical and Mounting:After mounting unit, clip on the front fascia (ensure that all locking clips have engaged) and secure with screw located inside the fuse panel door.Orientation: The unit is to be installed with the front fascia in a vertical plane. Failure to do this will cause premature temperature shut-down.Wiring UpMains: This is pre cabled and fitted with AS/NZ mains plug ready for connection to internal GPO. Ensure that the connection to the mains supply is in accordance with the national wiring rules, and that the earth connection is installed.Load, Battery and External DC Input Connections: Connectors are 0.8 x 6.3mm QC tabs. Use mating QC connector suitable for cable size. Connector pin-out is shown below.Cabling sizes: DC cables must be sized to carry the maximum full load current and not exceed the system volt drop requirements. The following cable sizes are recommended.Where cables pass through any part of a metal panel or cover, ensure that a cable gland or bush is fitted to the hole.Battery Connection Procedures:Battery should be connected as per the following steps.Turn power supply off and all 12 volt equipment connected to power supply.Connect positive battery terminal to “Batt +VE” power supply terminal.Connect negative battery terminal to “Batt -VE” power supply terminal or negative chassis ground.If battery is connected to chassis, ensure a connection exist from chassis to “Batt –VE”terminal of power supply.Battery Disconnection Procedures:Battery should be disconnected as per the following steps.Turn power supply off and all 12 volt equipment connected to power supply.Disconnect negative battery terminal connection to “Batt –VE” power supply terminal or negative chassis ground.1.Disconnect positive battery terminal to “Batt +VE” power supply terminal.BatteriesWhen using batteries with this product always consult with the battery manufacturer for a detailed description of the installation, use and maintenance of the battery.Ensure battery has been charged for several days before a major camping trip (Leave the power supply on for at least 2 – 5 days with battery connected).This product is suitable for charging 12V-Sealed Lead-Acid (SLA) batteries including Valve-Regulated Lead-Acid (VRLA) batteries both Absorbed Glass Mat (AGM) and Gel batteries. One or two batteries with max.100Ah capacity each can be charged. Charging current is limited to 10A (ST20-II) and 15A(ST35-II).ServicingPersonnel: This product contains hazardous voltages and energy hazards, which can result in death or injury. Only properly qualified service personnel may service it.There are no internal user serviceable parts. Only the fuses located in the “fuse panel” located on the front panel are serviceable.Isolate mains power, Vext and battery before servicing.Replacement of Fuses: Only the DC output Load and Battery fuses may be replaced.Fuse ratings: Load fuses 20A max, Battery Fuse 35A max.Fuse types: 32V Automotive Bussmann ATC series or Littelfuse 257 series or equivalentSpecificationInput Voltage:ST20-II & ST35-II: 230 – 240Vac nominal, ±10%, 50/60Hz.The power supply will withstand a 5 minute, +15% surge on themaximum nominal voltageInput Surge:< 40A (cold start)Hold-up Time:> 10mS at full load current and over nominal input voltage operatingrangeOutput Current:ST20-II: 20A Continuous (load + battery current)ST35-II: 35A Continuous (load + battery current)Factory Set Voltage 13.65V +/- 0.1V (Vfloat)Load Regulation:< 2%Output RippleVoltage:< 150mVOver VoltageProtection:< 17VOver Current Protection ST20-II: 20A to 25A (load + battery current) ST35-II: 35A to 38A (load + battery current)Battery Current Limit10A ± 1A (ST20-II)15A ± 1A (ST35-II)BatteryConnect/Disconnect Connect: 10.50 ± 0.2V (Input Mains not present) and first power up Connect: 11.70 ± 0.2V (Input Mains not present and not first power up) Connect: 11.50 ± 0.2V (Input Mains present)Disconnect: 10.0 ± 0.2VBattery TrickleCharge0.8A Battery Drain< 2mA.

The purpose is to ensure that the correct voltages are applied to the battery terminals at the appropriate times throughout it’s usage cycle.To prevent corrosion on the battery positive plate due to continuous float charging current (VFloat = 13.65V), the unit utilises a storage mode voltage (VStore = 13.25V) when no activity on the battery is detected. This extends the battery life. During store mode, the unit exits to boost mode (VBoost = 14.05V) for 15 minutes every 24hrs to maintain charge in the battery. If battery activity is detected during store mode it exits automatically into float mode.For any decision making involving the “loss of mains” detection there is a 2 minute mains debounce period where there must be no mains signal present on the mains detect input for the “no mains” signal to be valid.A detailed description of the operational requirements for the charging algorithm is describedbelow:N/A Microcontroller first powerup.Initial application of powerto the microcontrollereither from 240VAC mainsinput or connection of abattery to the battery input (Includes Auxiliary power).VfloatVfloat (No Mains Input)Mains input detected afterloss of mains for less than1 hour.Float charging mode withmains input voltagedetected (set 24 hourtimer).VfloatVboost Mains input voltage wasdetected for more than 15minutes.Float charging mode withmains input voltagedetected (set 24 hourtimer).VfloatVfloat No mains input voltage isdetected.Float charging mode withno mains input voltagedetected (set 1 hour timer).Vfloat (Nomains input)Vstore No mains input voltage isdetected.Float charging mode withno mains input voltagedetected (set 1 hour timer).Vfloat (Nomains input)Periodic_Vboost No mains input voltage isdetected.Float charging mode withno mains input voltagedetected (set 1 hour timer).Vfloat (Nomains input)Vfloat (No Mains Input)Mains input voltage wasdetected after being absentfor more than 1 hour.Loss of mains, boostcharging mode, active afterresumption of mains inputsupply (set 15 minute boosttimer).VboostVboost (No Mains Input)Mains input voltage wasdetected (this conditionmust also reset the 15minute boost period).Loss of mains boostcharging mode, active afterresumption of mains inputsupply (set 15 minute boosttimer).VboostVboost No mains input voltage isdetected.Boost charging mode whileno mains is detected.Vboost (NoMains Input)Vfloat Mains input voltage waspresent for more than 24hours.Battery storage mode (set24 hour timer).VstorePeriodic_Vboost Periodic boost voltagetimer has timed out.Battery storage mode (set24 hour timer).VstoreVstore Battery storage mode timerhas timed out.Periodic boost mode (set15 minute timer).Periodic_VboostBattery Charging Voltage Over TimeTimeST–III Series Power Supplies USER INSTRUCTIONSElectromagnetic compatibility (EMC)Electromagnetic compatibility (EMC) is defined as “the ability of a device, equipment or system to function satisfactorily in its electromagnetic environment without introducing intolerable electromagnetic disturbance to anything in that environment”.Switch-mode power supplies are good generators of EMI and as such care needs to taken during their designs to limit their emissions. Requirements of the local regulator (ACA) limit the emissions to protect the frequency spectrum. Limits are set down in standards such as EN55022 for radiated and conducted emissions. However, these limits are not satisfactory for devices in close proximity (<3m) and as such do not guarantee that the power supply will not cause interference with devices such as TV’s or radios.The ST20-III/35-III have been designed with equipment interoperability in mind. The emissions are in the order of 10 – 100 times below the regulator requirements (this is expressed in dB (µV)) and greatly reduce the likelihood of causing interference with Radios and TV’s located in close proximity.However, care still needs to be taken with the routing of cables and placement of the unit with respect to appliances. Small emissions can still cause interference. If interference is present, then locate cables from the power supply away from appliance so far as possible and also locate the power supply away as far as practical.Page 11 of 11Issue D。

Richtek RT7296C 3A 同步步进下降电源说明书
RT7296C 3A, 17V Current Mode Synchronous Step-Down ConverterGeneral DescriptionThe RT7296C is a high-efficiency, 3A current mode synchronous step-down DC/DC converter with a wide input voltage range from 4.5V to 17V. The device integrates 80mΩhigh-side and 30mΩlow-side MOSFETs to achieve high efficiency conversion. The current mode control architecture supports fast transient response and internal compensation. A cycle-by-cycle current limit function provides protection against shorted output. The RT7296C provides complete protection functions such as input under-voltage lockout, output under-voltage protection, over-current protection, and thermal shutdown. The PWM frequency is adjustable by the EN/SYNC pin. The RT7296C is available in the TSOT-23-8 (FC) package. Ordering InformationG : Green (Halogen Free and Pb Free) RT7296CNote :Richtek products are :④RoHS compliant and compatible with the currentrequirements of IPC/JEDEC J-STD-020.④Suitable for use in SnPb or Pb-free soldering processes.

If the input voltage exceeds the UVLO rising threshold voltage (3.9V), the converter resets and prepares the PWM for operation. If the input voltage falls below the UVLO falling threshold voltage (3.25V) during normal operation, the device stops switching. The UVLO rising and falling threshold voltage includes a hysteresis to prevent noise caused reset. Chip EnableThe EN pin is the chip enable input. Pulling the EN pin low (<1.1V) will shutdown the device. During shutdown mode, the RT7296C’s quiescent current drops to lower than 1μA. Driving the EN pin high (>1.6V) will turn on the device.Operating Frequency and SynchronizationThe internal oscillator runs at 1400kHz (typ.) when the EN/SYNC pin is at logic-high level (>1.6V). If the EN pin is pulled to low-level over 8μs, the IC will shut down. The RT7296C can be synchronized with an external clock ranging from 300kHz to 3MHz applied to the EN/SYNC pin. The external clock duty cycle must be from 20% to 80% with logic-high level = 2V and logic-low level = 0.8V. Internal RegulatorThe internal regulator generates 5V power and drive internal circuit. When VIN is below 5V, PVCC will drop with VIN. A capacitor (>0.1μF) between PVCC and GND is required. Soft-Start FunctionThe RT7296C provides external soft-start function. The soft-start function is used to prevent large inrush current while converter is being powered-up. TheRT7296Csoft-start timing can be programmed by the external capacitor between SS pin and GND. The Chip provides a 11μA charge current for the external capacitor. Over Current ProtectionRT7296C provides cycle-by-cycle over current limit protection. When the inductor current peak value reaches current limit, IC will turn off High Side MOS to avoid over current.Under Voltage Protection (Hiccup Mode)RT7296C provides Hiccup Mode of Under Voltage Protection (UVP). When the FB voltage drops below half of the feedback reference voltage, V FB , the UVP function will be triggered and the IC will shut down for a period of time and then recover automatically. The Hiccup Mode of UVP can reduce input current in short-circuit conditions. Thermal ShutdownThermal shutdown is implemented to prevent the chip from operating at excessively high temperatures. When the junction temperature is higher than 150︒C, the chip will shutdown the switching operation. The chip is automaticallyre-enabledwhenthejunctiontemperature cools down by approximately 20︒C.RT7296C Absolute Maximum Ratings(Note 1)●Supply Input Voltage, VIN ----------------------------------------------------------------------------------- -0.3V to 20V●Switch Voltage, SW-------------------------------------------------------------------------------------------- -0.3V to V IN + 0.3V<20ns--------------------------------------------------------------------------------------------------------------- -5V●BOOT to SW, V BOOT – SW ----------------------------------------------------------------------------------- -0.3V to 6V (7V for < 10μs) ●Bias Supply Output, PVCC---------------------------------------------------------------------------------- -0.3V to 6V (7V for < 10μs) ●Other Pins--------------------------------------------------------------------------------------------------------- -0.3V to 6V●Power Dissipation, P D @ T A = 25︒CTSOT-23-8 (FC) ------------------------------------------------------------------------------------------------ 1.428W●Package Thermal Resistance (Note 2)TSOT-23-8 (FC), θJA ----------------------------------------------------------------------------------------- 70︒C/WTSOT-23-8 (FC), θJC ----------------------------------------------------------------------------------------- 15︒C/W●Lead Temperature (Soldering, 10 sec.) ----------------------------------------------------------------- 260︒C●Junction Temperature ----------------------------------------------------------------------------------------- -40︒C to 150︒C●Storage Temperature Range ------------------------------------------------------------------------------- -65︒C to 150︒C●ESD Susceptibility (Note 3)HBM (Human Body Model) --------------------------------------------------------------------------------- 2kV Recommended Operating Conditions(Note 4)●Supply Input Voltage, VIN --------------------------------------------------------------------------------------- 4.5V to 17V●Junction Temperature Range ---------------------------------------------------------------------------------------- -40︒C to 125︒C●Ambient Temperature Range ---------------------------------------------------------------------------------------- -40︒C to 85︒C Electrical Characteristics(V = 12V, T = 25︒C, unless otherwise specified)RT7296Cstress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied.

Output Voltage SelectionThe resistive voltage divider allows the FB pin to sense a fraction of the output voltage as shown in Figure 1.OUTFigure 1. Output Voltage SettingFor adjustable voltage mode, the output voltage is set by an external resistive voltage divider according to the following equation :OUT FB R1V V 1R2=+⎛⎫⎪⎝⎭Where V FB is the feedback reference voltage (0.807V typ.). Table 2 lists the recommended resistors value for common output voltages.External Bootstrap DiodeConnect a 100nF low ESR ceramic capacitor between the BOOT pin and SW pin. This capacitor provides the gate driver voltage for the high side MOSFET. It is recommended to add an external bootstrap diode between an external 5V and BOOT pin, as shown as Figure 2, for efficiency improvement when input voltage is lower than 5.5V or duty ratio is higher than 65% .The bootstrap diode can be a low cost one such as IN4148 or BAT54. The external 5V can be a 5V fixed input from system or a 5V output (PVCC) of the RT7296C.Figure 2. External Bootstrap DiodeExternal Soft-Start CapacitorRT7296C provides external soft-start function. The soft-start function is used to prevent large inrushcurrent while converter is being powered-up. The soft-start timing can be programmed by the external capacitor (C SS ) between SS pin and GND. The Chip provides a 11μA charge current (I SS ) for the external capacitor. The soft-start time (t SS , V REF is from 0V to 0.8V) can be calculated by the following formula :SS SS SS C (nF) 1.3t (ms) = I (A)μ⨯Inductor SelectionThe inductor value and operating frequency determine the ripple current according to a specific input and output voltage. The ripple current ∆I L increases with higher VIN and decreases with higher inductance.OUT OUT L IN V VI 1f L V ⎛⎫⎛⎫∆=⨯- ⎪ ⎪⨯⎝⎭⎝⎭Having a lower ripple current reduces not only the ESR losses in the output capacitors but also the outputvoltage ripple. High frequency with small ripple current can achieve highest efficiency operation. However, it requires a large inductor to achieve this goal.For the ripple current selection, the value of ∆I L = 0.3(I MAX ) will be a reasonable starting point. The largest ripple current occurs at the highest V IN . To guarantee that the ripple current stays below the specified maximum, the inductor value should be chosen according to the following equation :OUT OUT L(MAX)IN(MAX)V V L 1f I V ⎛⎫⎛⎫=⨯- ⎪ ⎪ ⎪ ⎪⨯∆⎝⎭⎝⎭RT7296CThe inductor's current rating (caused a 40︒C temperature rising from 25︒C ambient) should be greater than the maximum load current and its saturation current should be greater than the short circuit peak current limit. C IN and C OUT SelectionThe input capacitance, C IN , is needed to filter the trapezoidal current at the source of the top MOSFET. To prevent large ripple current, a low ESR input capacitor sized for the maximum RMS current shouldbe used. The RMS current is given by :RMS OUT(MAX)I I 1= This formula has a maximum at V IN = 2V OUT , where I RMS = I OUT /2. This simple worst-case condition is commonly used for design because even significant deviations do not offer much relief.Choose a capacitor rated at a higher temperature than required. Several capacitors may also be paralleled to meet size or height requirements in the design. The selection of C OUT is determined by the required Effective Series Resistance (ESR) to minimize voltage ripple. Moreover, the amount of bulk capacitance is also a key for C OUT selection to ensure that the control loop is stable. Loop stability can be checked by viewing the load transient response as described in a later section. The output ripple, ∆∆V OUT , is determined by :OUT L OUT 1V I ESR 8fC ⎛⎫∆≤∆⨯+⎪⎝⎭The output ripple will be highest at the maximum input voltage since ∆I L increases with input voltage. Multiple capacitors placed in parallel may be needed to meet the ESR and RMS current handling requirement. Dry tantalum, special polymer, aluminum electrolytic and ceramic capacitors are all available in surface mount packages. Special polymer capacitors offer very low ESR value. However, it provides lower capacitance density than other types. Although Tantalum capacitors have the highest capacitance density, it is important to only use types that pass the surge test for use in switching power supplies. Aluminum electrolytic capacitors have significantly higher ESR. However, it can be used in cost-sensitive applications for ripplecurrent rating and long term reliability considerations. Ceramic capacitors have excellent low ESR characteristics but can have a high voltage coefficient and audible piezoelectric effects. The high Q of ceramic capacitors with trace inductance can also lead to significant ringing. Thermal ConsiderationsFor continuous operation, do not exceed absolute maximum junction temperature. The maximum power dissipation depends on the thermal resistance of the IC package, PCB layout, rate of surrounding airflow, and difference between junction and ambient temperature. The maximum power dissipation can be calculated by the following formula : P D(MAX) = (T J(MAX) - T A ) / θJAwhere T J(MAX) is the maximum junction temperature, T A is the ambient temperature, and θJA is the junction to ambient thermal resistance.For recommended operating condition specifications, the maximum junction temperature is 125︒C. The junction to ambient thermal resistance, θJA , is layout dependent. For TSOT-23-8 (FC) package, the thermal resistance, θJA , is 70︒C/W on a standard JEDEC 51-7 four-layer thermal test board. The maximum power dissipation at T A = 25︒C can be calculated by the following formula :P D(MAX) = (125︒C - 25︒C) / (70︒C/W) = 1.428W for TSOT-23-8 (FC) packageThe maximum power dissipation depends on the operating ambient temperature for fixed T J(MAX) and thermal resistance, θJA . The derating curve in Figure 3 allows the designer to see the effect of rising ambient temperature on the maximum power dissipation.RT7296CFigure 3. Derating Curve of Maximum PowerDissipationLayout ConsiderationsFor best performance of the RT7296C, the following layout guidelines must be strictly followed.Input capacitor must be placed as close to the IC as possible.SW should be connected to inductor by wide and short trace. Keep sensitive components away from this trace.Keep every trace connected to pin as wide as possible for improving thermal dissipation.SW should be connected to inductor by Wide andVia can help to reduce power trace and improve thermal dissipation.trace wider for thermal.Figure 4.

三里屿 PR-25 电源修理指南说明书
TrippLite PR-25 Repair Notes – Rich N1IXFRecently, a ham friend asked me to look at his PR-25 power supply and fix it if I could. In that process, I learned that there is very little information available to help guide a ham’s repair of one of these TrippLite power supplies. For example, it is next to impossible to find a schematic diagram or any circuit descriptions for these power supplies. I did manage to find an on-line copy of a schematic for the PR-60 and with that I explored the power supply I wanted to fix. The quality of the only available schematic was a bit rough, so I decided to draw one as I proceeded to troubleshoot the circuit. I even found a mistake in the main fuse location. These notes don’t describe the troubleshooting process that I undertook but I hope they will give you a better picture of the power supply and what to look for if you must repair one.The PR-25 is a 13.8 VDC / 20A continuous duty linear power supply using negative regulation. That negative regulation is something I’m not used to, and it took a while to wrap my head around the schematic. Here’s a block diagram to go along with the schematic I created (see below):Step-Down Transformer, Rectifier, and Filtering –The power supply uses two center tapped secondary windings to step the 120 VAC input down to approximately 17.6 VAC each side of the high current windings and 4.5 VAC each side of the other secondary windings. The high current supply uses a rectifier module attached to its own heatsink. This rectifier supplies two parallel diodes for each side of the center tap. The unfiltered DC is passed to a parallel bank of five 6800 uF filter capacitors ( totaling 34 mF of capacitance). The filtered DC measured 22.5 VDC on the PCB with the filter caps, emitter resistors and pass transistors. The other secondary is used for the supply to the drive transistor (Q1) and is rectified by D1 & D2 and filtered by C2 (6800 uF). This measures 5.5 VDC at the collector of Q1 (2N6388).Voltage Regulation and Current Limiting Foldback Circuits–This power supply uses a LM614CN as the core of the voltage regulation and current limiting foldback circuit. It is powered with 21.9 VDC at pin 4 (Vcc) through D3 and a separate filter cap, C1 and ground at pin 13. The LM614CN contains a precision voltage reference that can be programmed with external resistors and four operational amplifiers in a single 16 pin DIP. According to the datasheet, the reference voltage is set by selecting two external resistors (R2 & R3 in the power supply). With those values, the Vro (reference voltage output) will be 5.5 VDC at pin 9. That reference voltage is adjusted with the variable voltage divider feeding pin 5 (RV8 and R9). The voltage adjustment provided by this potentiometer is used to set 13.8 VDC at the output terminals.The op amp (section U2-B) is configured as a negative voltage comparator, it produces an output voltage by comparing the input voltage (Vin) at pin 6 against the established reference voltage (Vref) at pin 5. When Vin is less than Vref, the op amp’s output will saturate toward Vcc. When Vin is greater than Vref, the op amp’s output will saturate towards the negative supply rail, ~0V. The op amp’s output supplies the bias to the power supply drive transistor, Q1. I believe the RC network (R18 and C5) between the inverting input and the output provide some hysteresis and transient stability to the comparator.Section U2-A of LM614CN samples the power supply output voltage and provides Vin to section U2-B just discussed above. This op amp is configured as a differential amplifier where the output of the op amp will be a bit more than one-third (R4/R5 = 6.65k/18.2k = 0.365) of the difference between the supply’s output voltages that are placed across the resistors on the inverting and non-inverting pins.Section U2-D is configured as a comparator to form the core of the power supply’s current limiting foldback circuit. This circuit senses the load current at the pass transistor’s emitter resistors (R25 and R26) and compares the resulting voltage across that resistor combination with the reference voltage from the resistor network at the non-inverting input of the comparator. It effectively switches off the power supply by shunting the drive transistors’ bias if the sense voltage is larger than the reference voltage. By adjusting the current limiting foldback potentiometer RV15 and, in turn, the reference voltage at pin 14, the current limit of the supply can be set.Crowbar Circuit –The crowbar circuit is a straightforward implementation of the basic configurations detailed in the MC3423 (U1) datasheet. This circuit provides over-voltage protection as it “…senses the overvoltage condition and quickly “crowbars” or short circuits the supply, forcing the supply into current limiting or opening the fuse (hopefully!)…”The trip voltage threshold is adjustable by selecting the values of the voltage divider resistors at the sense pin 2 of U1. In the case of the PR-25 power supply, R22 (14.7k) and R23 (2.61k) set that threshold at 17.24V [ Vtrip = 2.6V(1+(14.7k/2.61k)) ]. A delay can also be programmed by selecting a capacitor (C7) which determines the minimum duration of the over-voltage condition which is necessary to trip protection. In our case, the 1 uF capacitor provides a delay of 13 ms.Output Filtering & Bleeder Resistor -As noted on the schematic, C6, a 2200 uF capacitor across the output terminals of the power supply helps to filter any sags or spikes due to sudden changes in the load. C21 provides high frequency bypass for any RF noise entering the terminals and the bleeder resistor R25 will slowly discharge the power supply’s filter capacitors when it is powered down.Test Voltages –Here’s a table of voltages from the working power supply without a load attached:。
数据中心对电源的基本要求
数据中心对电源的基本要求《数据中心电源那些事儿》嘿，咱今天就来聊聊数据中心对电源的那些基本要求。
这可是个大事儿啊，就好比人得吃饭一样，数据中心没了可靠的电源，那就得瘫痪啦！咱先说这稳定性吧，电源可不能三天两头抽风啊！要是一会儿有电一会儿没电的，那数据中心里的那些宝贝数据不得哭死啊，说不定顺手就给你来个数据大逃亡，那可就麻烦大啦。

数据中心的电源得经得住考验，不能关键时刻掉链子呀！有时候我就想啊，这数据中心对电源的要求咋跟咱人找对象似的呢。
要稳定可靠，不能一会儿好一会儿坏；要能长时间陪伴，不能半途而废；要足够强大，能撑起一个家；还要质量好，没那么多毛病。
哈哈，这么一联想还挺有意思呢！总之啊，数据中心的电源那可是重中之重，马虎不得。
咱得好好伺候着这些电大爷们，让它们好好工作，这样咱们的数据才能安安全全、稳稳当当的。
所以呢，那些负责数据中心电源的小伙伴们可得上点心啦，可别让这些电源调皮捣蛋哦！。

TD230005EN 电力容器参考数据 效果：2017年3月初发布 新发布 COOPER POWER
Group fusing is generally used for protecting pole-mounted distribution capacitor racks. In this type of application, the fuse links are installed in cutouts and mounted on a cross arm above the capacitor rack.The main purpose of the fuse on a capacitor rack is to clear a fault if a capacitor unit or anyof the accessories fail. The fuse must clear the fault quickly to prevent any of the equipment from failing violently and to assure continuous operation of the rest of the system (the unfaulted portion).The fuses must be sized to withstand normal currents, including harmonics, inrush, and outrush. This document describes the following considerations for selecting a group fuse:• Continuous current• Transient current• Fault current• Tank rupture curve coordination• Voltage on good capacitors Continuous currentThe fuse protecting the capacitor is chosen such that its continuous current capability is equal to or greater than 135% of rated capacitor current for grounded-wye connected racks, and 125% for ungrounded-wye racks. This overrating includes the effects of overvoltage, capacitor tolerance, and harmonics. The minimum size fuse link for a grounded-wye application is calculated as follows:This calculation is based on the link being 150% rated. That is, in the case of 150% NEMA typeT and K tin links, they can carry 150% of rated current continuously.1Transient currentFuses can be damaged due to high-magnitude, high-frequency currents. It is desirable to minimize spurious fuse operations by selecting an appropriately large fuse link so as to withstand these transient currents.Three sources of transient currents are capacitor bank switching, lightning surges, and discharge through to external faults (primarily on grounded-wye systems).Switching is typically only a concern when capacitor banks are switched on the same bus, i.e., back-to-back switching. This is seldom the case for pole-mounted capacitors. However, capacitor fuses are subject to high-frequency transients due to lightning surges and discharges through external faults.1 The 150% current-carrying capability applies to tin links,not silver links. Silver T and K links can carry 100% oftheir rating continuously.Group Capacitor Fusing for Pole-Mounted Capacitor Banks in Grounded and Ungrounded Wye Applications2Reference Data TD230005ENEffective March 2017Group Capacitor Fusing for Pole-Mounted Capacitor Banksin Grounded and Ungrounded Wye Applications/cooperpowerseriesFault currentThe fuse link/cutout and the capacitor must be able to handle the available fault current adequately. When capacitors are connected grounded-wye or delta in a pole-mounted rack application, a capacitor failure (terminal-to-terminal) will cause system fault current to flow. The capacitor must be able to withstand the fault current until the fuse interrupts the circuit. Additionally, the fuse must be able to successfully interrupt the available fault current.The available symmetric fault current should not exceed the limits shown in Table 1 or the limits for the selected cutout.T able 1.

This is generally a more cost-effective solution.2 In this type of connection, the available current is limited to three times the line current due to the impedance of the capacitors in adjacent phases. See Table 1 for proper fuse selection. (If a majorinsulation failure or simultaneous failures in two phases should occur, then fault current could flow. These events are usually very rare and are normally not considered when applying fuses in an ungrounded-wye application.)•Move the capacitor rack to a location with an acceptable fault current level.2 Additional factors must be considered for operating the bank ungrounded-wye. Capacitor units need to have two bushings and, if the bank has a switch, the switch should be capable of handling the transient recovery voltage (TRV) present in an ungrounded-wye installation.Tank rupture curve coordinationThe maximum clearing time-current curve (TCC) for the fuse link must coordinate with the tank rupture curve for the capacitor. This coordination is necessary to ensure that the fuse will clear the circuit prior to tank rupture occurring.For the maximum fault current, the fuse should melt and clear at a time faster than the corresponding time on the tank rupture curve for that fault current level. In other words, the fuse maximum clear TCC must fall below the tank rupture TCC curve at and below the level of available fault current. In the case of high fault currents, the tank rupture curve should be compensated for asymmetry.In general, the largest fuse size recommended for coordination with the tank rupture curve for the Cooper Power Series type SD, HD and XD capacitors is a NEMA 100K link and a NEMA 65T link. (See publications R230-91-1, R230-91-2, R240-91-1, and R-240-91-2 for tank rupture curves and fuse time-current curves.)Voltage on good capacitorsFor ungrounded-wye capacitor banks, the voltage on the goodcapacitor units, when one is shorted, is equal to system line-to-line voltage, i.e., 1.73 times its rating. If the failed unit is not cleared from the circuit quickly, this high overvoltage condition could lead to a second capacitor failure, resulting in a phase-to-phase fault. For this reason, it is desirable to use the fastest clearing fuse possible so as to minimize the possibility of a second unit failure. This criterion pushes for a fast-clearing fuse, such as a K-link, while the transient-current criterion dictates a slow-clearing fuse, such as a T -link. Therefore, fuse-selection criteria for ungrounded-wye applications are more restrictive than for grounded-wye applications.3Reference Data TD230005ENEffective March 2017Group Capacitor Fusing for Pole-Mounted Capacitor Banks in Grounded and Ungrounded Wye Applications /cooperpowerseries Summary of group fusing recommendations for pole-mounted capacitor racksTable 2 and Table 3 list group fusing recommendations for the Cooper Power Series type SD, HD and XD capacitors.
