EVAL-KIT-1000031-01 Evaluation KIT for Paralleled 3-Phase PFC Converters

SummarySynQor has developed EVAL-KIT-1000031-01, an evaluation board to facilitate testing of our Paralleling 3-Phase PFC converters and its associated 3-Phase, differential mode AC line filters.

Introduction

This application note is a guide to the features, schematic, component placement, and BOM for this evaluation board. The applicable modules are MACF-115-3PH-UNVD-QT 3-Phase differential AC Line Filters and MPFC-115-3PH-270P-FP 3-Phase PF converters.

Appendix A – Bill of Materials (BOM)

This evaluation board and schematic are intended for demonstration purposes only and no guarantees are made for standards compliance.

Shock Warning: There are areas of this evaluation board that have exposed access to hazardous high voltage levels. These are non-isolate PFC modules with the output return voltage referenced to the input AC line. Exercise caution to avoid contact with those voltages. Also note that the evaluation board may retain high voltage for up to 1 second after input power has been removed. Exercise caution when handling.

Thermal Considerations: When testing converters on an evaluation board, ensure adequate cooling. Apply cooling air with a fan blowing across the converter or across a heatsink attached to the converter. Monitor the converter temperature to ensure it doesn’t exceed the maximum rated per the datasheet specification.

Application Note



Section 1 – Converter DescriptionThe 3-Phase PFC converter has two stages. The input stage takes 3-Phase AC (115 Vrms L-N / 200 Vrms L-L) and shapes and balances the three AC input currents. Phase relation (A, B, C phases) are not connection specific. The PFC will work in any orientation. The output of the first stage is called +MIDBUS and it has an external capacitor on the evaluation board (see Capacitor Bank on the Evaluation Board section of the application note for more details). +MIDBUS voltage ranges from 160 Vdc to 220 Vdc over specified operating conditions. The +MIDBUS is then fed into a second stage that has a typical output voltage of 270 Vdc. The 3-Phase PFC will startup and operate under any valid load condition.

Isolation Warning

Circuitry on this evaluation board is non-isolated with respect to the AC line inputs. This requires great care in making connections and taking measurements. Be aware that the output 270 Vdc and +MIDBUS 200 Vdc are non-isolated with respect to input AC lines. As such, take great care before taking any measurement with equipment that may make a connection to ground. The return line for either DC voltage is NOT ground. Connecting a scope probe to any power DC voltage on this board may result in damage to the board and/or the scope or scope probe. Use isolated differential probes or clamp on style current probes to avoid these issues. Note that the shield pin connects to a shield that lies between the converter and the baseplate and is meant to provide noise reduction in cases where the baseplate is connected to a heatsink that can become a noise radiator. For safety, DO NOT CONNECT THE SHIELD TO THE BASEPLATE as the shield is line referenced. In most applications, the output of the 3-Phase PFC is followed by an isolated DC-DC converter. The serial port and enable switch are isolated.

Application Note



Section 2 – Evaluation Block Diagram / Typical Application

Notes:Note 1: SHIELD pin must be left floating, but may be externally connected to the plane under the unit near the top of PCB to contain high frequency EMI.Note 2: CB & RP are for stabilizing the system when DC-DC converters are used as the PFC module’s load. Additional Hold-Up capacitance may be required for normal operation through interruptions in input power.

Section 3 – Input and Output Connections

Input power is applied through connector J16, see Table 1. The mating connector for J16 is DF22-4S-7.92C (28) from Hirose Electric Company in Japan and is provided.

Output power is applied through connectors J10 and J11 or J6 and J7. See Table 2. The mating connectors are provided.

+MIDBUS is connected to J6, see Table 2.

Application Note



Table 3: Test Points

All high voltage test points have a red color indicating a High Voltage Differential Probe must be used. This prevents a connection between the scope ground and -VOUT/+VOUT/+MIDBUS/LINE_X which are all at AC line potential. All black colored test points are referenced to CTL_RETURN and are safe to use a standard scope probe.

Note: Please refer to the appropriate SynQor converter datasheet for descriptions of these features.

Application Note



Section 6 – Component PlacementAll high voltage test points have a red color indicating a High Voltage Differential Probe must be used.This prevents a connection between the scope ground and -VOUT/+VOUT/+MIDBUS/LINE_X which are all at AC line potential. All black colored test points are referenced to CTL_RETURN and are safe to use a standard scope probe.

Application Note



Section 7 – Basic Operating Instructions

Apply the 3-Phase input, 115 Vrms (L-N) at J16 on left, using the provided cable assembly. Earth ground, and Phases A, B, and C are labeled. There is no neutral connection, and phase rotation (A, B, C) does not matter to the device. Lamps LI1, LI2, LI3 indicate the presence of hazardous voltages at the input.

Connect the loads at:

+MIDBUS for loosely regulated 200 Vand/or +VOUT for regulated 270 V

Use Switch S1 in lower right for enable / disable control.

Be aware that the output 270 Vdc and +MIDBUS 200 Vdc are non-isolated with respect to input AC lines. As such, take great care before taking any measurement with equipment that may make a connection to ground. The return line for either DC voltage is NOT ground. Connecting a scope probe to any power DC voltage on this board may result in damage to the board and/or the scope or scope probe. Use isolated differential probes or clamp on style current probes to avoid these issues.

All high voltage test points have a red color indicating a High Voltage Differential Probe must be used. This prevents a connection between the scope ground and -VOUT/+VOUT/+MIDBUS/LINE X which are all at AC line potential. All black colored test points are referenced to CTL RETURN and are safe to use a standard scope probe.

Measurements may be taken or a downstream converter added to test the PFC in an evaluation system.

Capacitor Bank on the Evaluation Board

The test board includes a small amount of output capacitance on the MAIN OUTPUT (270 Vdc). Although no large bulk hold-up capacitance is required for operation, the device will require a nominal amount of capacitance at the +MIDBUS node for normal operation. The capacitors selected are rated from -55 °C to 125 °C, and arranged in groups in series strings due to their voltage rating. A single larger value electrolytic capacitor would also be acceptable. Capacitors on the output nodes serve to stabilize the input system both for this converter and downstream power converters.

Capacitors are solid polymer electrolytic for good ESR at low temperature and lifetime at high temperature. The highest voltage rating for Nichicon PCR is 80 V continuous so capacitors are wired in series with active balancing.

On-Board Capacitance: 91 µF @ +MIDBUS_0 91 µF @ +MIDBUS_1 34 µF @ +VOUT

Each +MIDBUS, 0 and 1, has 4 sets of 3 series capacitors in parallel for a total of 24 capacitors +VOUT has 2 set of 4 series capacitors in parallel for a total of 8 capacitors

Please refer to the applications section of the datasheet for more detailed information on additional capacitance.

Application Note



Additional Information

Two LEDs below the AC GOOD (Green) and DC GOOD (Red) test points (Below S1) indicate the status of the AC GOOD and DC GOOD signals. An Orange LED below J14 indicates that 3.3V AUX from PFC_0 is on.

The PCB and PFC modules have means in place for shield layers on both the PCB itself, under the module and between the baseplate and module, as part of the 3-Phase PFC full brick. The baseplate retains electrical isolation. These layers are in place to reduce EMI radiation. The evaluation board and PFC modules properly connect these shields.

Serial Interface Communications

To communicate with adaptor board kit, a DB9 Male to DB9 Female and USB RS232 adaptor are required.
