On Board Charger
Automotive (onboard) chargers are AC/DC converters that convert the household AC (100V to 240V) supply to DC in order to charge the high voltage battery array. To ensure universal compatibility, most onboard chargers support a wide voltage range, usually between 85V and 265V. However, due to input voltage fluctuations, safer and more efficient devices are required.
In addition to isolator ICs, ROHM offers a broad range of power devices, including SiC SBDs.
