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