An onboard charger (OBC) is a system built into a vehicle for recharging high-voltage batteries from the AC grid during parking. The core of any electric (EV) or plug-in hybrid (HEV) vehicle lies in high-voltage (200 to 450VDC) batteries and their associated charging systems. Split type high-voltage components are widely used in OBC (in car chargers) applications and have replaced an increasing number of module based solutions due to price pressures.

Hongmei has a rich range of discrete semiconductor products, including Trench FS II technology IGBT and Super Junction TF series MOSFET, which can provide cost-effective and energy-efficient solutions to meet these challenging converter requirements.

Hongmei has launched the Super Junction MOSFET III series products. By optimizing the device structure design and adopting advanced manufacturing technology, the product performance has been further improved, with better avalanche resistance and ESD capability, improving the reliability of device applications. At the same time, this series of products adopts independent innovative technology to optimize the switching characteristics of devices, making them have better EMI performance in system applications, providing greater margin for system design.
