Applications/Examples of results
The shift to 800V is driving demand for automotive power devices. In the automotive power device market, the transition from 400V to 800V in vehicle power architecture is boosting the demand for high-voltage devices. The 800V system allows for the transmission of the same power at a lower current, making it easier to reduce losses during charging and the weight of cables, leading to its adoption primarily in fast-charging EVs and high-performance BEVs. STMicroelectronics is also developing 1200V-class SiC devices and products for high-voltage power distribution for the 800V architecture, and it is expected that the voltage classes of automotive power devices will further diversify in the future.
