How to use the 3 kW three-channel interleaved PFC based on the STNRGPF01
digital controller
Introduction
The STEVAL-IPFC01V1 3 kW interleaved PFC reference design is based on the STNRGPF01 digital controller and includes a
separate power board, control board and programming board. The STNRGPF01 is a digital configurable ASIC developed by
STMicroelectronics, which can drive up to three channels in an interleaved PFC for industrial applications.
The
STNRGPF01
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
STNRGPF01
to
satisfy the specifications of each interleaved PFC.

    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 charge current is limited by resistor R101. UM2520 - Rev 3 page 5/28...

  • Page 6: Figure 6. Steval-Ipfc01V1 Dc Input Connection

    If the load is connected before the Inrush current limiter phase, a very high current will flow into the PFC and possibly damage the board when the relay closes the contacts across resistor R101. UM2520 - Rev 3 page 6/28...
