Vienna 3-Phase Power Factor Correction (PFC) Reference Design

The MSCSICPFC/REF5 is a 3-phase Vienna PFC reference design for Hybrid Electric Vehicle/Electric Vehicle (HEV/EV) charger and high-power switch mode power supply applications. This reference design achieves 98.5% efficiency at 20 kW output power and is capable of operation to 30 kW.

Key Features of this Reference Design:

  • Designed for 30 kW applications
  • Our next-generation 1200V Silicon Carbide IC (SiC) diodes and 700V SiC MOSFETs with high avalanche/repetitive Unclamped Inductive Switching (UIS)
  • 3-phase 380/400V RMS input voltage, 50 Hz or 60 Hz
  • 140 kHz switching frequency
  • 780V DC output voltage
  • PCB layout optimized for safety, current stress, mechanical stress and noise immunity
  • dsPIC33CH Digital Signal Controller (DSC) for digital control
