Technolog y for the automotive future MAIN INVERTER ELECTRIC COMPRESSOR DC/DC CONVERTER xEV is driven by a high-voltage battery and motor instead of the engine. The DC/DC converter converts the power device from the high voltage battery to a low DC voltage using a transformer. In order to protect the electronic circuits operating at low voltage, it is necessary to electrically isolate both the ground and signal from the low voltage board and high voltage board. Also, ROHM's DC/DC converter system that uses SiC MOSFET enables high-speed switching operation, achieving miniaturization and high performance...

MAIN INVERTER | | DC/DC CONVERTER ELECTRIC COMPRESSOR ON BOARD CHARGER Onboard chargers (car chargers) consist of AC/DC converters that convert AC voltage (100V to 240V) to DC voltage to charge the high-voltage battery. To ensure worldwide compatibility, the permissible input voltage of many onboard chargers ranges from 85V to 265V. And to meet market needs for shorter charge times, the voltage specified under fast charging standards has increased along with battery voltage. As a result, onboard chargers are trending towards higher permissible input voltage, accelerating the use of SiC not only...
