Power modules

Power modules are widely applied in areas including communications, industrial control, computers and peripherals, consumer electronics, medical, aerospace, and new energy. As far as EV charging is concerned, the power module plays a vital role of being the core part of the charger test system, responsible for providing stable working voltage and current, ensuring that chargers can simulate the real charging environment during the test process, and comprehensively testing its performance, safety, and reliability. The efficient and stable performance is of great significance to support the safe and reliable operation of EV charging facilities.
