STEVAL-IPFC01V1

STEVAL-IPFC01V1 is a 3kW interleaved PFC reference design. It 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.
