GaN-based single-phase bridgeless PFC boost rectifier

Abstract

A single-phase GaN-based bridgeless PFC Boost converter design is proposed regarding multi-domain optimisation concepts. A design guideline describing elements losses are presented concerning the selected power converter topology. Experimental results are also depicted in 750 W power prototype digitally controlled by an FPGA device using switching frequency up to 500 kHz per active switch.
