Product overview

Description

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.
