Wolfspeed grows to meet supply challenge and launches high performance Gen 3+ die June, 01 2022
Silicon Carbide (SiC), known for long as the ideal semiconductor technology for power devices, has with design and manufacturing innovation not only increased its share of the existing market but enabled new applications, such as electric vehicles (EVs), by offering higher power density, better high-speed switching performance, higher breakdown field, higher thermal conductivity, higher chip temperatures, and lower leakage currents than are possible with Silicon (Si).

Enhancing Power Conversion from Watts to Megawatts with 1700 V SiC MOSFETs - May 2022 May, 03 2022
In the world of power electronics, bigger is never better. This holds particularly true for high-voltage power systems, where designers are clamouring for better semiconductor technology to meet customer demand for converters that are smaller, lighter, more reliable and efficient, and less expensive. With Silicon MOSFETs and IGBTs, compromises must be made; for example, one must select either the most reliable design or the most efficient design, but not both...
