What are the uses of silicon carbide?

Silicon carbide (SiC), as a new semiconductor material, has the advantages of silicon carbide: smaller volume, more efficient, complete removal of switching losses, low drain current, higher switching frequency than standard semiconductors (pure silicon semiconductors), and the ability to work above the 125 ° C junction temperature of silicon carbide standards.

The silicon carbide forward conductor performs the switching action quickly between the high current and the reverse cutoff kV voltage, and this performance is worth trying. The first successful application of SiC and the main application of hair diodes are used in automotive headlights and other instrument panel lighting. Other markets include switching power supplies and Schottky barrier diodes. Future applications include hybrid vehicles, power converters (to reduce the volume of active prefilters) and AC/DC motor control.

These more demanding applications have not yet been commercialized because they require high-quality materials and large-scale productivity to reduce costs. Worldwide, significant research dollars have been invested in companies, laboratories, and government facilities to make SiC technology more viable. Some experts predict that the commercialization, industrialization and even military applications of SiC technology will become a reality in 2 to 5 years or more.
