Abstract

Silicon carbide (SiC) device-based converters have better efficiency and power density than the ones based on Silicon (Si) devices. The gate driver design for the SiC switches becomes critical due to the high dv/dt during switching transients. This paper details the design considerations for a dual gate driver for converters utilizing a SiC MOSFET switches. Gate driver attributes are identified based on the design consideration. A hardware prototype is developed based on the design criteria. A low complexity isolated gate driver power supply is built with a compact 3 core 3 winding transformer configuration and a significant reduction in primary to secondary transformer parasitic capacitance is shown in both simulation and from the hardware results. © 2023 IEEE.
