Abstract
High speed switching is desired to reduce switching losses of SiC-MOSFETs. In order to realize SiC-MOSFETs capable of high speed switching, we numerically evaluated the electric field induced in SiC-MOSFETs during switching using an equivalent circuit model. Based on the evaluation, we designed a SiC-MOSFET, which successfully demonstrated high speed switching with a dV/dt of over 70 V/ns.
