STNRGPF12数字控制器的2 kW双通道交错PFC使用说明书
IntroductionThe STEVAL-IPFC12V1 2 kW interleaved PFC kit is based on the STNRGPF12 digital controller and consists of a power board,control board and adapter board. The STNRGPF12 is a digital configurable ASIC developed by STMicroelectronics, which can drive up to two channels in an interleaved PFC for industrial applications.The STNRGPF12 digital controller on the control board implements mixed signal (analog/digital) average current mode control in CCM at fixed frequency. The analog section ensures cycle-by-cycle current regulation, while digital control manages the non-time-critical operations. You can use the eDesignSuite software available on the ST website to configure the STNRGPF12 to satisfy the specifications of each interleaved PFC.Figure 1.STEVAL-IPFC12V1 evaluation kit with power, control and adapter boardsHow to use the 2 kW two-channel interleaved PFC based on the STNRGPF12digital controllerUM2537User manualSafety instructions 1Safety instructionsDanger:The evaluation board uses voltage levels that can cause serious injury and even death.Do not touch any components immediately after disconnecting the input power supply as thecharged capacitors need time to discharge.Due to the high power density, board components and heat sinks can become very hot and causesevere burns when touched.This board is intended for use by skilled technical personnel who are suitably qualified and familiar with theinstallation, use and maintenance of power electronic systems. The same personnel must be aware of and mustapply national accident prevention rules.The electrical installation shall be completed in accordance with the appropriate requirements (e.g., cross-sectional areas of conductors, fusing, and GND connections).STEVAL-IPFC12V1 evaluation kit overview 2STEVAL-IPFC12V1 evaluation kit overviewFigure 2. STEVAL-IPFC12V1 block diagram1.I/O measurement signals2.Analog circuitry3.Power stages4.The STEVAL-IPFC12V1 implements mixed signal (analog/digital) control, combining the flexibility of aprogrammable high end digital solution with the responsiveness and accuracy of analog componentry. The innercurrent loop consists of an analog proportional-integral (PI) compensator that ensures the highest possiblebandwidth and cycle-by-cycle regulation. The outer voltage loop is performed by a digital PI controller with fastdynamic response.2.1Board featuresThe 2 kW interleaved PFC evaluation kit features:• A modular design with the following separate boards:–STEVAL-IPFC12P1 power board–STEVAL-IPFC12C1 control board–STEVAL-IPFC01A1 adapter board•2-channel interleaved PFC•Input voltage range: 90 to 265 V AC (50 or 60 Hz)•Maximum output power: 2 kW at 230 V AC; 1 kW at 115 V AC;•Output voltage: 400 V•Fixed frequency average current mode control and CCM operation•Mixed-signal, semi-digital approach•Programmable phase shedding•Cooling System management•Programmable fast overcurrent and thermal protection•Digital inrush current limiter function performed with relay•Soft startup and burst mode management•Load current and input voltage feed forward•Channel current balance functionBoard features•Two status LEDs to signal nominal and fault conditions•Browser GUI tool (eDesignSuite) for driver customization•Serial communication port for–STNRGPF12 programming–PFC parameter monitoring3How to use the STEVAL-IPFC12V1 evaluation boardTo perform functional and efficiency testing, you need the following equipment:•Programmable AC source with power > 2 kW •DC electronic load or load resistor > 2 kW •Power analyzer •Digital oscilloscopeThe STEVAL-IPFC12V1 board can be tested up to 2 kW at 230 V RMS and 1 kW at 115 V RMS , in a frequency range between 47 and 63 Hz.Note:Any load or passive oscilloscope probe must be isolated from the input source of the PFC.3.1How to connect and start the STEVAL-IPFC12P1 power boardStep 1.Insert the STEVAL-IPFC12C1 control board in connector J301 on the STEVAL-IPFC12P1 power board.Step 2.Connect one of the following AC supplies to the J100 connector on the STEVAL-IPFC12P1 power board:–230 V at 50 Hz –115 V at 60 HzFigure 3.STEVAL-IPFC12P1 AC supply connectionHow to use the STEVAL-IPFC12V1 evaluation boardStep 3.Connect the load wires to the output terminals on J300 of the STEVAL-IPFC12P1 power board.The actual load (electronic dc load, load resistors, inverter, etc.) must remain disconnected until thesoft startup sequence has completed.The correct polarity is indicated on the board.Figure 4. STEVAL-IPFC12P1 DC output connectionStep 4.Supply one of the following input voltage and frequency ranges while no load is connected on the output:–185 – 265 V AC at 47 - 53 Hz–90 – 140 V AC at 57 – 63 Hz3.1.1STEVAL-IPFC12P1 power board startup sequence1.The appropriate AC input voltage is applied under a no load condition.2.When the input voltage rises above 60 V, the auxiliary power supply starts and generates the auxiliaryvoltages (15 V DC and 5 V DC) for the drivers and the signal conditioning circuitry.3.Once the auxiliary voltages are nominal, the inrush current limiter phase begins by charging the outputcapacitor until the DC voltage reaches the peak input voltage. The current is limited by the SCRs Q102 andQ103.Figure 5. STEVAL-IPFC12P1 input section4.The STNRGPF12 then checks for any output current flow:–If there is no current, the STNRGPF12 closes the contacts of a mechanical relay in parallel with resistor R101.–If any current is detected, the STNRGPF12 will keep the relay contacts on R300 open (so the board cannot start) until the current falls to zero.5.After the inrush limiter phase, the soft startup procedure is activated and the output voltage rises up to 436VDC, at which point the PFC enters burst mode to regulate the output voltage between 416 and 436 VDC.6.The green LED D2 on the control board indicates when the sequence has finished and the PFC is ready forthe load to be connected.7.Once you connect the load:–the output voltage is regulated to 400 V ±2 V.–for 185 – 265 V 50 Hz mains, the maximum output power is 2000 W –for 90 – 140 V 60 Hz mains, the maximum output power is 1000 W4PFC controller customization with eDesign SuiteThe eDesignSuite suite software tool developed by STMicroelectronics helps you configure ST products powerconversion applications. You can use it to customize the PFC controller for a specific application: you start byentering the main specifications for your design and then generate an automatic design or follow a sequentialprocess to build a highly customized design.Figure 6. PFC specificationsFigure 7. PFC step-by-step designRELATED LINKSSee RM0446 for details on how to use eDesignSuite to generate specialized firmwareStatus LEDs and fault conditions 5Status LEDs and fault conditionsThe STEVAL-IPFC12C1 control board has the following status LEDs:• a green LED connected to STNRGPF12 pin 15 (PFC_OK)• a red LED connected to STNRGPF12 pin 14 (PFC_FAULT)5.1Normal operationDuring normal operation, the green LED (D1) on the STEVAL-IPFC12C1 control board remains lit to indicate thatthe PFC is operating under allowable conditions.5.2Fault conditionsWhen a fault is detected, the red LED (D2) on the STEVAL-IPFC12C1 control board lights up and the green LED(D1) turns off. The device stops all switching activities and turns off the fan.After a fault condition, the board must be reset by switching off the AC input voltage and discharging the outputcapacitors.Note:Warning: Do not short the output terminals to discharge the capacitors as the high discharge current may damage the output current sensing circuitry.The following conditions will trigger a fault protection:• A mismatch between frequency and voltage or highly distorted input voltage waveforms that inhibit frequency measurement. For example, if the input voltage is 230 V RMS but the mains frequency is 60 Hz, orif the input voltage is 115 V RMS and the mains frequency is 50 Hz.•Overcurrent condition on at least one PFC channel. This protection prevents PFC inductor saturation.•Overvoltage protection on output voltage if the output voltage exceeds 440 V DC•Overvoltage protection on input voltage:–for 115 V nominal supply: above 140 V–for 230 V nominal supply: above 265 V•Over-temperature protection when the ambient temperature of the board exceeds the threshold setting. 5.3Wait conditionsIn addition to the conditions that trigger PFC_OK and PFC_FAULT, there are other conditions that are indicatedwith both LEDs are off:•Undervoltage condition on the output when the DC bus voltage falls below 340 V.•Undervoltage condition on input when the input rms voltage falls below 90 V at 60 Hz or 185 V at 50 Hz.•Input voltage dropout when the input voltage signal disappears for more than 25 ms.Under these conditions, the STNRGPF12 will drive both LEDs on the control board off and will wait until theconditions have cleared before repeating the startup sequence.UM2537STEVAL-IPFC12V1 schematic diagrams 6STEVAL-IPFC12V1 schematic diagrams6.1STEVAL-IPFC12P1 power board schematicsFigure 8.STEVAL-IPFC12P1 schematic - input sectionSCR SWINPUT__2701SWSW270___SCR R107V 2_R104UM2537STEVAL-IPFC12P1 power board schematicsFigure 9.

All rights reserved. is a registered trademark of Richtek Technology Corporation.DS7313-01 July 20161PFC Controller with Critical Conduction ModeGeneral DescriptionThe RT7313 is an active Power Factor Correction (PFC) controller with critical conduction mode (CRM) operation that is designed to meet line current harmonic regulations for the applications of AC/DC adapters, electronic ballasts and medium off-line power converters (<300W). The CRM and Feed-Forward schemes provide near unity power factor across a wide range of input voltages and output powers.The totem-pole gate driver with 600mA sourcing current and 800mA sinking current provides powerful driving capability for power MOSFET to improve conversion efficiency. The RT7313 features an extra low start-up current (≤20μA) and supports a disable function to reduce power consumption in standby mode, which makes it easy to comply with energy saving regulations such as Blue Angel, Energy Star and Energy 2000.This controller integrates comprehensive safety protection functions for robust designs including input under-voltage lockout, output over-voltage protection, under-voltage protection and cycle-by-cycle current limit.The RT7313 is a cost-effective solution for PFC power converter with minimum external components. It is available in the SOP-8 package.Features● Critical Conduction Mode (CRM) Operation ● Constant On-Time Control (Voltage Mode) ● Near Unity Power Factor● Ultra Low Start-up Current (≤20μA)● Input Voltage Feed-Forward Compensation ● Wide Supply Voltage Range from 12V to 25V ● Totem Pole Gate Driver with 600mA/-800mA ● Maximum Frequency Clamping (120kHz) ● DCM THD Optimization ● Fast Dynamic Response● Light Load Burst Mode Operation ● Disable Function● Maximum/Minimum On-Time Limit ● Cycle-by-Cycle Current Limit● Output Over-Voltage Protection (OVP) ● Under-Voltage Lockout (UVLO) ●RoHS Compliant and Halogen FreeApplications● Electrical Lamp Ballast ● LED Lighting●AC/DC Adapter/Charger for Desktop PC, NB, TV, Monitor, Etc.●Entry-Level Server, Web ServerSimplified Application CircuitPSR ConverterOUT +OUT -SSR ConverterOUT +OUT -OUT1OUT2RT7313Copyright © 2016 Richtek Technology Corporation.

Figure 1 shows the CRM operating at the boundary between Continuous Conduction Mode (CCM) and Discontinuous Conduction Mode (DCM).In CRM, the power switch turns on immediately when the inductor current decreases to zero. The CRM is the preferred control method for medium power (<300W) applications due to the features of zero current switching and lower peak current than that in DCM.Figure 1. Inductor Current of DCM, CRM and CCM Constant On-Time Voltage Mode ControlFigure 2 shows a typical flyback converter. When the MOSFET turns on with a fixed on-time (t ON ), the inductor current can be calculated by the following equation (1).TX1OUTV OUTFigure 2. Typical flyback ConverterIN L_PK ON PFCVI = t (1)L⨯If the input voltage is a sinusoidal waveform and rectified by a bridge rectifier, the inductor current can be expressed with equation (2). When the converter operates in CRM with constant on-time voltage modecontrol, the envelope of inductor peak current will follow the input voltage waveform with in-phase. The average inductor current will be half of the peak current shown as Figure 3. Therefore, the near unity power factor is easy to be achieved by this control scheme.||||IN_pk ONL_pk PFCV sin θt I sin θ=(2)L ⨯⨯⨯I L_PK I Q1I in_avg I DOUTPeak Inductor Current MOSFET Current Average Input Current Output Diode CurrentV IN Input Voltage V Q1_GATE MOSFET Gate VoltageFigure 3.

An internal 29V zener diode is also used to avoid over voltage stress for the internal circuits.When the VDD is available, the precise reference is generated for internal circuitries such as Error Amplifier, Current Sense, OVP, UVP. The internal reference equips with excellent temperature coefficient performance so that the RT7313 can be operated in varied environments.RT7313Copyright © 2016 Richtek Technology Corporation.

VDD and UVLOFeedback Voltage DetectionFigure 5 shows the feedback voltage detection circuit. The INV pin is the inverting input of the Error Amplifier with 1.5V reference voltage. Over-voltage protection is provided with threshold voltage 1.65V. If the INV voltage is over 1.65V, the gate driver will be disabled to prevent output over voltage condition or feedback open condition. Although the INV is an input pin with high impedance, it is suggested that the bias current of the potential divider should be over 30µA for noise immunity.Figure 5. Feedback Voltage DetectionTransconductance Error AmplifierThe RT7313 implements transconductance error amplifier with non-linear GM design to regulate the Flyback output voltage and provide fast dynamic response. The transconductance value is 100µA/V in normal operation. When the INV voltage increases over 1.65V or decreases under 1.35V, the output of error amplifier will source or sink 1.5mA(typ.) maximum current at COMP pin respectively shown as Figure 6. Thus, the non-linear GM design can provide fast response for the dynamic load of PFC converters even though the bandwidth of control loop is lower than linefrequency.Figure 6. Non-linear GMFeed-Forward CompensationThe FF pin is an input pin with high impedance to detect the line input voltage shown as Figure 7. A proper voltage divider should be applied to sense the line voltage after bridge diode rectifier. Since the FF voltage is proportional to the line input voltage, it provides a feed-forward signal to compensate the loop bandwidth for high line and low line input conditions.Figure 7.

Ramp GeneratorThe RT7313 provides constant on-time voltage mode control to achieve near unity power factor for the CRM Flyback converters. Figure 8 shows the Ramp Generator with Feed-Forward compensation and THD optimization circuit for the constant on-time operation.Figure 8. Ramp GeneratorThe charging current of ramp generator is modulated following the squared FF voltage with line voltage compensation and the THD optimization scheme is implemented to compensate the harmonic distortion. ZCD and Enable FunctionIn CRM operation, when the power switch turns on, the inductor current increases linearly to the peak value. When the power switch turns off, the inductor current decreases linearly to zero. The zero current can be detected by the ZCD pin with the auxiliary winding of Flyback inductor.Figure 9 and Figure 10 show the ZCD block diagram and related waveforms. The ZCD block diagram provides zero current detection, voltage clamp and shutdown control functions. When the inductor current decreases to zero, the auxiliary winding voltage will turn from high to low. Once the ZCD voltage decreases to the threshold V ZCDT (1V, typ.), the controller will generate a signal for gate driver. The hysteresis voltage between the threshold V ZCDA (1.6V, typ.) and V ZCDT is designed to avoid mis-triggering. In order to prevent over voltage stress, the ZCD pin voltage is clamped at V ZCDH (4.8V, typ.) if the input voltage is too high from the auxiliary winding and the ZCD pin voltage is clamped at V ZCDL (0.6V, typ.) if the input voltage is lower than V ZCDL .RT7313Copyright © 2016 Richtek Technology Corporation.

When the ZCD pin is pulled lower than 250mV, the gate driver will be turned off and operate in standby mode with low quiescent current less than 600µA. Once the ZCD pin is released, the controller will be activated.The RT7313 also provides ZCD time-out detection function. If the controller runs at maximum frequency and there is no ZCD signal being detected after 4µs delay time, the PWM will be turned on for ZCD time-out detection.V V I V V V VFigure 10.

Start-Up Waveforms of VDD and I DD Figure 11 and Figure 12 show the equivalent start-up circuit and VDD waveform during start-up. In general, the start-up time (t start ) is required from system specification. The charging current (Ich VDD ) can be estimated by the following equation.VDD ON_THVDD startC V Ich = (8)t ⨯where C VDD is the capacitor connected between VDD and GND, V ON_TH is the power on threshold (16V typ.). The start-up resistor (R start ) connected between V CSIN and VDD should be able to support the charging current (Ich VDD ), start-up current (I DD_ST ) and leakage current (I leakage ) of C VDD before the VDD is supported by the auxiliary winding. The maximum start-up resistance can be calculated by the equation (9).Start DD_ST VDD leakageRwhere V IN ac_min is the minimum input voltage. Note that the start-up resistor must have adequate voltage rating for reliability. 2 resistors in series can be applied for most of applications.For example, the system required start-up time is 3sec, V IN ac_min = 75V and maximum I DD_ST = 20μA. If C VDD = 22μF is selected and the leakage current of C VDD can be ignored, the start-up resistor should be less than 772k Ω.The capacitor C FF is applied to filter out the input ripplevoltage. The corner frequency should be lower than line frequency (f line ). If the FF pin voltage is not flat, the PF and THD performance will be degraded.line FF1FF2FF1 < 0.1f (10)2(R // R )C π⨯⨯⨯Thermal ConsiderationsFor continuous operation, do not exceed absolutemaximum 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 SOP-8 package, the thermal resistance, θJA , is 160︒C/W on a standard JEDEC 51-3 single-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) / (160︒C/W) = 0.625W for SOP-8 packageThe maximum power dissipation depends on the operating ambient temperature for fixed T J(MAX) and thermal resistance, θJA .

Derating Curve of Maximum PowerDissipation Layout ConsiderationsA proper PCB layout can abate unknown noise interference and EMI issue in the switching power supply. Please refer to the guidelines when designing a PCB layout for switching power supply.④The current path(1) from input capacitor, transformer, MOSFET, R CS return to input capacitor is a high frequency current loop. The path(2) from GD pin,MOSFET, R CS return to input capacitor is also a high frequency current loop. They must be as short as possible to decrease noise coupling and kept a space to other low voltage traces, such as IC control circuit paths, especially. Besides, the path(3) between MOSFET ground(b) and IC ground(d) is recommended to be as short as possible, too.④It is good for reducing noise, output ripple and EMI issue to separate ground traces of input capacitor(a), MOSFET(b), auxiliary winding(c) and IC control circuit(d). Finally, connect them together on input capacitor ground(a). The areas of these ground traces should be kept large.④Placing bypass capacitor for abating noise on IC is highly recommended. The capacitors C INV and C CS should be placed as close to controller as possible. ④In addition, apply sufficient copper area at the anode and cathode terminal of the diode for heat-sinking. It is recommended to apply a larger area at the quiet cathode terminal. A large anode area will induce high-frequency radiated EMI.NeutralFigure 14.
