Analysis of Influence of Insulation Failure of Drive Transformer on Drive Circuit of SiC MOSFET

The driving circuit plays an important role in the normal operation of a power electronic product. The driving power supply with the driving transformer as the main device is an important part of the driving circuit. Therefore, the performance of transformer parameters has a great impact on the drive circuit. The distributed parameters in high-frequency transformer will have adverse effects on power electronic products. This paper focuses on the influence of insulation failure in distributed parameters on SiC MOSFET drive circuit. A driving circuit for SiC MOSFET is designed, and the hardware circuit of the circuit is built. The influence of insulation failure on the driving circuit is simulated by software, and the influence of insulation failure on the driving circuit is verified by hardware circuit.
