Performance evaluations of capacitor-switched PSFB converter with SiC MOSFETs

In this paper, a silicon-carbide based capacitor-switched phase-shifted full bridge DC-DC converter circuit for electrical vehicles is investigated. The state-of-the-art silicon-carbide components were used as switching power devices. The reduction of conduction and switching losses has been achieved by using silicon-carbide devices. As a consequence, the performance of the converter is increased and weight and volume of the circuit are reduced.
