AbstractWe evaluated and compared the dynamic properties of the megahertz switching of two kinds of commercial valve devices during high-speed operation. The two devices were a silicon (Si) power MOSFET (2SK2847, Toshiba) and a silicon carbide (SiC) power MOSFET (SCT2080KE, Rohm). Because the purpose for both the use and the package side were similar, our focus was mainly on how the Si and SiC materials contributed to the device performance. We evaluated the conversion efficiency in terms of both the energizing loss and the switching loss. Results showed that the SiC power MOSFET had a high withstand voltage and a high threshold voltage and that the electrical resistance of the conduction state was smaller than that of the Si power-MOSFET. The experimentally obtained switching loss of the SiC power MOSFET was smaller than that of the Si power MOSFET at 1-MHz frequency operation.
