Description
Summary:In many applications of power electronic converters efficiency and size are important figures of merit. Low losses in the power semiconductors as well as high frequency operation are important factors to obtain compact and highly efficient converters. The converters considered in this paper are off-line industrial power supplies (~100 kW) operating at a switching frequency range of 20-40 kHz. Replacing Si power devices by SiC counterparts enables both lower losses and increased switching frequencies. In this paper, experimental results from SiC PiN diodes, (output rectifiers) and SiC MOSFETs, (active switches) are presented.
