Performance evaluation of CoolMOS/sup /spl trade// and SiC diode for single-phase power factor correction applications

The low conduction loss and switching loss characteristics make CoolMOS/sup /spl trade// and SiC diode attractive for the single-phase CCM PFC converters. In this paper, based on the device level and converter level evaluation, the loss reduction capability of the CoolMOS/sup /spl trade// and SiC diode is quantified. In addition, for the first time, a successfully operating 1 kW 400 kHz single-phase CCM PFC is demonstrated by using CoolMOS/sup /spl trade// and SiC diode.
