This article is focused on an industrial auxiliary power supply based on flyback topology using a 1.7kV SiC MOSFET as the main switch. The goal of this article is to show applicable circuit providing the interface between a standard PWM controller (a PWM controller dedicated to an Si MOSFET) and an SiC MOSFET. The features are described and verified using an industrial SMPS designed for operation of input power for the range of 150VDC to 1kV DC.
