The switching behavior is different for a few of the SiC MOSFETs, such as CAS300M12BM2 from Cree Inc. As shown in Fig. 1(c) and Fig. 1(d), SiC MOSFETs exhibit a non-flat gate-plateau voltage region, with V gs increasing from V p1 to V p2, while V ds reduces to V ds(on) during turn-on, and vice-versa during turn-off, which makes it difficult
