G2V and V2G operation 20 kW battery charger

摘要

This paper presents a bidirectional on-board battery charger for Electric Vehicles designed to perform both\udGrid to Vehicle (G2V) and Vehicle to Grid (V2G) operation. The charger can also operate with single or\udthree-phase power grid connection, regulates the battery charging current and presents input unity power\udfactor. A high frequency three-phase transformer has been included in the charger, this providing galvanic\udisolation.
