Experimental Verification of Maximum Operating Frequency for a SiC-MOSFET in Class-D ZVS inverter

This paper experimentally verified a previously proposed analytical model of maximum operating frequency of class-D ZVS inverter. The proposed model included the linearized drain-source parasitic capacitance and was usable at any duty ratio. The verification of the model was once conducted by simulation with a 650V/30A SiC-MOSFET spice model before, and in this paper the experimental verification was further conducted by PCB circuit, resulting in good consistency.
