Design and experimental validation of a silicon carbide 100kW battery charger operating at 60kHz

This paper presents the design and development of a 100kW Silicon Carbide battery charger operating at a switching frequency of 60kHz. The main aspects of the converter design such as the topology, the gate driver and the electromechanical design are described in the paper. The converter has been developed and experimentally validated at full rate.
