Abstract

Numerous studies have shown that the Si IGBT/SiC MOSFET hybrid switch has been verified to be a high-efficiency and cost-effective device for the application of the inverter. In fact, the high switching frequency of the SiC MOSFET means high dv/dt, which will generate severe common-mode electromagnetic interference (CM EMI). Meanwhile, it would lead to some malfunction of the power converter. In order to suppress the CM EMI of the single-phase inverter based on the Si/SiC hybrid switch, a CM EMI suppression strategy combining the variable switching patterns and the variable switching frequency will be proposed. Furthermore, the feasibility of the proposed method has been verified by experimental results distinctly.
