Abstract

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