Introduction with EV Industry
Electric Vehicles(EV) are increasingly becoming a part of modern life; its tremendous fuel economy, eco-friendliness, and smooth driving feel have appealed to many conscious modern consumers. EVs are quite different from traditional vehicles with internal combustion engines. Electric Power Control Unit(EPCU) The Electric Power Control Unit(EPCU) is an efficient integration of nearly all devices that control the flow of the electric power in the vehicle. It consists of the inverter, the Low voltage DC-DC Converter(LDC), and the Vehicle Control Unit(VCU). Inverter Power inverters and converters are used to invert HV battery pack direct current (DC) to alternating current (AC) for motors that propel the vehicle down the road; they also convert AC to DC to charge the HV battery pack. With an electric drivetrain, the inverter controls the electric motor in a manner somewhat equivalent to how the Engine Control Unit (ECU) of a gas or diesel internal combustion engine vehicle determines the
