The most basic function of an IGBT is the fastest possible switching of electric currents, thus achieving the lowest possible switching losses. As the name "Insulated Gate Bipolar Transistor" reveals, an IGBT is a bipolar transistor with an isolated gate structure; the gate itself is basically a MOSFET. Therefore, the IGBT combines the advan-

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.
