Onboard Battery Chargers - Passenger Car Electric Powertrain

Onboard battery chargers convert alternating current from charging stations to direct current for electric truck, bus, and heavy-duty EV batteries. A block diagram highlights Littelfuse components that can serve as rectifiers, dc–dc converter gate drivers, and circuit protection devices for OBCs. Available products include thyristors, TVS diodes, and high-voltage fuses.
