On Board Charger (OBC) is used to charge the high voltage battery pack of Battery Electric Vehicles (BEV) and Plugin Hybrid Electric Vehicles (PHEV). It is integrated directly into the vehicle's design and enables the conversion of AC power from the grid into DC power suitable for the vehicle's battery pack. This technology allows EV owners to conveniently recharge their vehicles at home or at public charging stations.

The best in class automotive power semiconductors, including EliteSiC MOSFETs, EliteSiC diodes, silicon Super-Junction (SJ) MOSFETs, hybrid IGBTs, and Automotive Power Modules (APMs), enable customers to maximize power density, efficiency, and reliability for their OBC designs. Customers can design OBC power stages that address 3.3 kW up to 22 kW and battery voltages up to 800 V using onsemi solutions. Galvanically isolated gate drivers can be paired with any power switch and chosen topology for PFC and DC/DC power stages. onsemi designed specialized gate drivers to complement EliteSiC MOSFET range and ensure optimized efficiency and reliability for high-power OBC.
