Jun 06, 2020· In this context SiC semiconductors – e.g. SiC MOSFETs for 800-volt battery systems – offer more efficient switching in the inverter (higher frequency, steeper switching slopes) and cause fewer harmonic losses in the electric motor. Also, SiC technology is a key enabler for super-fast charging technology that uses 800 volts.
Complex component geometries, like optimum efficiency ventilators for heat treatment furnaces, can therefore be realized without machining. By infiltrating the printed component with silicon, a carbon reinforced silicon carbide ceramic is created, which offers a high ductility in coination with resistance against corrosive atmospheres and a
