Hitachi Energy Semiconductor's journey in power electronics began in Switzerland 100 years ago. Nowadays, we have devices including thyristors, diodes GTO、IGCT、 Diversified semiconductor product lines including IGBT. We have advanced production facilities and professional research teams in Lenzburg and Prague, constantly promoting innovation in silicon and silicon carbide technology, and committed to the research and development of the next generation of power electronic equipment. Hitachi Energy's advanced semiconductor technology is the core of HVDC transmission, power quality, and electronic transportation solutions, which enable a large amount of renewable energy to be reliably transmitted between countries through the power grid. At the same time, they are also key technologies for driving traction inverter systems for high-speed electric trains, subways, and electric vehicles, which can promote the development of public transportation towards a cleaner and more efficient direction, and help all mankind move towards a more sustainable future
