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.
