SiC Single Switch Resonance Reset Forward converter with ZVS for AC-DC Power Supplies

摘要

An overview and the extension of the modern single switch, single ended power converters into higher power ranges with utilisation of SiC power devices (SiC JFET, Diodes and SiC Thyristor) is presented. Selected Resonant Reset Forward topology is discussed in detail. Simple topology modification (ZVS) for power and efficiency increase is shown and compared with conventional topologies. Experimental results of the proposed converter with SiC JFET are presented as a simple solution for high efficiency, high power density and cost effective AC-DC converters.
