Power devices are widely used in power control for industrial machinery, automobiles, home appliances and more. Today, as society moves toward carbon neutrality, the commercialization and spread of next-generation power devices that can reduce power loss during control holds great promise. Among these devices, GaN power devices feature high-speed operation, but higher breakdown voltage for higher power operation has been an issue in wider application.
World-class power of 800V and On/Off operation of one millionth of a second was confirmed2 using a module equipped with an originally designed GaN power device3 under development by Toyoda Gosei and Powdec. This demonstration of a power device that offers both high-voltage and high-speed operation is promising for reduced power loss in solar power generation and other benefits. The companies are aiming to assure stable continuous operation and durable quality for early commercialization.

2 High performance with both high-voltage operation (800V) and high-speed operation (On/Off operation of one millionth of a second) is among the highest in the world (as of the end of May, 2023 in a survey by Toyoda Gosei)
3 Polarization Super Junction GaN power transistor. It features high breakdown voltage of ≥1500 V.
