SiC is a compound of group IV carbon and group IV silicon. Based on its properties of low resistivity, good carrier (mobility) velocity, high breakdown electric field, and excellent heat dissipation, SiC power devices are superior to traditional Si-based ones in the aspects of low on-resistances, low junction capacitances and gate charges. Furthermore, the excellent properties and device characteristics can not only fasten operating frequencies and elevate conversion efficiencies, but also facilitate miniaturized packaging and design of heat dissipation in module- or system-end products. Current mainstream applications include automotive, industrial power supplies , power regulators, variable ( voltage ) frequency converters, power converters...etc. Other related applications are being augmented increasingly.
