How to use the 2 kW two-channel interleaved PFC based on the STNRGPF02 digital controller Introduction The STEVAL-IPFC02V1 2 kW interleaved PFC kit is based on the STNRGPF02 digital controller and consists of a power board, control board and adapter board. The digital configurable ASIC can drive up to two channels in an interleaved PFC for industrial applications.
UM2674 Safety instructions Safety instructions Danger: 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 the charged capacitors need time to discharge. Due to the high power density, board components and heat sinks can become very hot and cause severe burns when touched.
Power stages Digital control section The STEVAL-IPFC02V1 implements mixed signal (analog/digital) control, combining the flexibility of a programmable high end digital solution with the responsiveness and accuracy of analog componentry. The inner current loop consists of an analog proportional-integral (PI) compensator that ensures the highest possible bandwidth and cycle-by-cycle regulation.

DC electronic load or load resistor > 2 kW • Power analyzer • Digital oscilloscope The STEVAL-IPFC02V1 board can be tested up to 2 kW at 230 V and 1 kW at 115 V , 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.
UM2674 How to connect and start the STEVAL-IPFC02P1 power board Step 2. Connect the load wires to the output terminals on J300 of the STEVAL-IPFC02P1 power board. The actual load (electronic dc load, load resistors, inverter, etc.) must remain disconnected until the soft startup sequence has completed.
UM2674 How to connect and start the STEVAL-IPFC02P1 power board Once the auxiliary voltages are nominal, the inrush current limiter phase begins by charging the output capacitor until the DC voltage reaches the peak input voltage. The current is limited by resistor R101 until it is shorted by the relay RL100 at the end of inrush phase.
PFC controller customization with eDesignSuite eDesignSuite software tool developed by STMicroelectronics helps you configure ST products for power conversion applications. You can use it to customize the PFC controller for a specific application by entering the main specifications for your application and generating an automatic design, or by following a guided process for more specific designs.
UM2674 Status LEDs and fault conditions Status LEDs and fault conditions The STEVAL-IPFC02C1 control board has the following status LEDs: • a green LED connected to STNRGPF02 pin 15 (PFC_OK) • a red LED connected to STNRGPF02 pin 14 (PFC_FAULT) Normal operation During normal operation, the green LED (D2) on the STEVAL-IPFC02C1 control board remains lit to indicate that the PFC is operating under allowable conditions.
