A Single Stage Sepic Converter for Electric Vehicles Charging

This proposed system is about bidirectional power flow for charger of an E-Vehicles. The charger connected with PV source is designed, modelled, and implemented. In this topology, the output charging current is regulated by DC-DC converter. The bidirectional interleaved isolated SEPIC converter is proposed in this paper for charging the electric vehicle. The multi-step constant current charging method is used for charging operation. This reduces the number of power electronic components, which in turn minimizes the power loss. Simulation is carried out in MATLAB/Simulink, and the results are obtained, which shows that battery can be charged with this topology.
