What is silicon carbide? Silicon carbide is a compound made of silicon and carbon. This compound is found in a mineral called moissanite. The natural form of silicon carbide is named after the French pharmacist Dr. Ferdinand Henri Moissan. Moissanite is usually found in meteorites, kimberlite and corundum. As a result, most commercial silicon carbide is synthetic. Although it is difficult to find naturally occurring silicon carbide on Earth, it is quite abundant in space.
What advantages does silicon carbide have? The characteristics of silicon carbide include stable chemical properties, high thermal conductivity, low thermal expansion coefficient, good wear resistance, high hardness (Morse hardness of 9.5, second only to the world's hardest diamond (grade 10), excellent thermal conductivity, strong oxidation resistance at high temperature and so on.
Silicon carbide semiconductor Because silicon carbide has incomparable excellent properties, silicon carbide is a kind of wide band gap semiconductor materials, which is mainly characterized by high thermal conductivity, high saturation, electron drift rate and high impact field strength, so it is used in all kinds of semiconductor materials. Silicon carbide devices mainly include power diodes and power switches. Power diodes include JBS diodes, PiN diodes and superjunction diodes, while power switches mainly include metal oxide semiconductor field effect switches (MOSFET), junction field effect switches (JFET), bipolar switches (BJT), insulated gate bipolar transistors (IGBT), gate turn-off thyristors (GTO) and emitter turn-off thyristors (ETO). Silicon carbide semiconductor devices, with the characteristics of high frequency, high efficiency and high temperature, are especially suitable for applications that require strict efficiency or temperature. It can be widely used in solar inverter, vehicle power supply, motor controller of new energy vehicle, UPS, charging pile, power supply and other fields.
What is silicon carbide inverter? Silicon carbide-based inverters are known for providing higher power density than traditional inverters, while requiring less cooling and lower overall system costs.
