Abstract : On board battery charger is an essential part of plug-in electric vehicle technology. In medium powered electric vehicles, level II battery chargers are preferred, which contains AC-DC power factor corrected converter and DCDC converter in two stages. Bridgeless interleaved (BLIL) boost topology is a preferred PFC converter in level II battery charger with higher converter efficiency. The proposed work deals with cascading of BLIL boost topology with full bridge dc-dc converter in closed loop for battery charging. Analysis over problems associated with open loop operation and closed loop operation of BLIL, while it is cascaded with full bridge converter is carried out using MATLAB/Simulink computer simulation.
