Infineon Technologies ICE5QSAG | Demoboard EVAL-PFC5KIKWWR5SYS

Description

This user manual provides an overview of the reference design developed for the EVAL-PFC5KIKWWR5SYS board,including its main features, key data, and mechanical dimensions.EVAL-PFC5KIKWWR5SYS is a fast switching, analog-controlled two-channel interleaved 5 KW PFC converter with Infineon’s TRENCHSTOP™ 5 WR5 IGBT IKW40N65WR5. It is designed to show case the use of WR5 IGBT with high switching frequencies up to 60 kHz in an interleaved PFC application, which enables many system benefits such as smaller size PFC choke, overall system size and BOM cost. This document also demonstrates a very effective example of design with Infineon’s low side gate driver 1ED44175 and rapid1 power silicon diode IDW60C65D1.The evaluation board has a flexible input AC voltage between 180-264 V, and provides a 400 V output voltage with maximum current up to 12.5 A. This document provides suggestions on how to develop interleaved PFC converters in similar power ranges adapted to specific requirments such as high-power SMPS, floor-standing air conditioners in major home appliances.
