Abstract

This paper reviews charging power levels and implementation of battery chargers using PFC AC-DC converters for Plug-in Hybrid Electric Vehicles. PHEV has 3 levels of charging, Level 1, Level 2 and Level 3, which are explained in this paper. Power Electronics devices used in the PHEV battery charging units creates harmonics in the system resulting in a low power factor. The traditional electric vehicle charging system uses diode bridge rectifier topology in cascade with DC-DC converter. Diode bridge rectifiers have some disadvantages: diode bridge causes considerable losses in the system and it creates a heat management problem. So we go for a bridgeless topology for Plug-in Hybrid Electric Vehicle charging. Interleaving is another attractive technique which helps to increase the operating power level. In this paper different PFC converter topologies are compared and Simulation analysis of Bridgeless Interleaved Boost converter is also presented
