An Efficient Resonant Converter Based Charging Scheme for Electric Vehicle

Abstract

The acceptance of electric vehicle around the world, represents a brand new paradigm for the transportation sector and for the particular and future power grids. Generally electric vehicles employ on board chargers. This paper suggests another candidate for isolated unidirectional DC/DC converter in electric vehicle on-board charger based on Full bridge- LLC resonant converter. Here a simple method is proposed to improve the charging profile. The circuit possess the inherent advantages like good voltage regulation performance at light load conditions and soft switching of power devices. The feasibility of proposed model has been verified with MATLAB/Simulink.
