WebMar 31, 2024 · Abstract. The superior electrical and thermal properties of silicon carbide (SiC) power electronic devices, compared with silicon (Si) devices, lead to high efficiency and low volume in power converter designs. In this paper, the simulation model of the SiC MOSFETs is built, and the dynamic and static performance is obtained.
