In this paper, the performance of high-voltage (10kV) 4H-SiC n- and p-channel IGBTs and n-channel MOS-Gated Bipolar Transistor (MGT) are investigated and compared using 2- dimensional numerical simulations. We have found that the MGT in SiC is not suitable for applications at high blocking voltages and the p-channel IGBT is a better choice because of a much higher conductivity modulation in the drift region.
