Drive SiC MOSFETs optimally to minimize conduction and switching losses. Minimize gate losses. The gate driver needs to be capable of providing +20 volts and -2 volts to -5 volts negative bias, with minimum output impedance and high-current capability. Pay attention to system parasitics, especially at the faster switching speed.

Among SiC MOSFET structures, the trench MOSFET has a low channel resistance thanks to its high channel density and mobility[5, 6]. However, in a high-voltage SiC MOSFET (a voltage of 3.3 kV or above), the channel resistance does not have a significant effect because of the high drift resistance. In addition, at high voltages, the trench MOSFET ...

In the past, SiC MOSFETs have been fabricated on 4H-SiC(0001). However, the on-resistance is much higher than the expected value because of the low channel mobility, which is due to the high interface state density (Dit) at the SiO2/SiC interface. In order to reduce the Dit, 4H-SiC(11-20)(3) or 4H-SiC(000-1)(4) was employed and nitridation(5 ...
