Onboard chargers (OBCs) must convert AC grid power to DC battery voltage efficiently and safely, isolating the high voltage battery from the AC input while meeting increasingly challenging power density, efficiency, thermal stability, EMI performance, and long service life requirements.
Vishay's Automotive Grade optocouplers provide the reinforced isolation OBC designs need between the grid-connected and battery-side circuits, while SiC MOSFETs and MOSFET power modules deliver the high frequency, low loss switching that shrinks charger size and weight. Our DC-Link film and aluminum electrolytic capacitors stabilize the power stage and inductors offer EMI suppression.
Behind the onboard charger efficiency is The DNA of tech.®
