The SiC-IGBT had a higher switching speed and significantly lower loss than Si-IGBT. At the same time, it was obtained that SiC-IGBT could work with high efficiency and high power density. It was then determined that SiC-IGBT modules achieved greater efficiency than Si-IGBTs in the single-pulse test and three-phase-based applications.

IGBT can only increase after the Miller capacitance has been fully discharged. This effect is also visualized in Fig. 4 where the Miller plateau seen in gate-emitter voltage of the Si IGBT is considerably longer than that of the SiC MOSFET. The component characteristics have a similar effect on the turn-on transient voltages of both transistors.
