DC EV CHARGER

As electric vehicle market grows, the demands for fast EV charging system are increasing for various purpose. Power of DC EV charging is increasing by modular configuration as demand of faster charging time and higher battery capacity of EV. DC EV charging system is classified into three categories to meet various needs in different places.

DC Wall EV charger box installed in house (~20kW/120min.)

Commercial high power DC EV charger installed in office/mall or EV charging station (50~150kW/50~20min)

Ultra fast DC EV charger installed in EV charging station (~350kW/7min.)

DC EV charging provides a mostly constant current output for wide DC output voltage range (200V to 900V) and load profile (single /multiple vehicles)

Topology Trend : PFC : Three-phase Vienna PFC → Three-phase full bridge (B6) / DC-DC : Series FB LLC → FB LLC
