Abstract
Silicon Carbide (SiC) N-channel Insulated Gate Bipolar Transistors (n-IGBTs) rated higher than 10kV can improve Medium Voltage and High Voltage power electronics due to the favourable combination of SiC material with the nIGBT device structure. This paper investigates the phenomenon of unintentional turn-on occurring due to high dV/dt produced during switching transients and analyses the impact of design parameters such as the channel length, the p-well doping and the oxide thickness for their ability to suppress it.
