Advanced Integrated Bidirectional AC/DC and DC/DC Converter for Plug-In Hybrid Electric Vehicles

Abstract

PHEVs have a high energy capacity battery pack which can only operate on electrical power for a given period. The battery pack can be recharged by a nearby socket. A novel combined bidirectional ac / dc adapter and dc / dc converter (henceforth combined converter) for PHEVs and electric / plugin electric conversions is introduced in this article. The integrated converter is capable of acting as an ac / dc battery adapter and of transmitting electrical energy between the battery pack and the high-voltage bus of the electrical traction network. It is seen that the integrated converter has a decreased number of high-current inductors and current transducers and has provided fault current tolerance for PHEV conversion.
