Abstract

With the increasing global warming and pollution issues, the transport sector needs to be modified to a green energy based travelling system since this is the only sector which employs quarter of the whole world's energy. It also, is the main contributor to CO2 emissions. Therefore, here an EV (Electric Vehicle) could be the best alternative to solve above issues. To improve the energy utilization of an EV, an attention is needed by the battery charging phenomenon. When an EV battery is charged from a conventional AC-DC converter, it draws a peaky current from the supply and hence makes the whole power profile and indices worst. Therefore, this paper presents a solution to the poor power quality issues. A PFC (Power Factor Correction) converter based on Sheppard Taylor converter topology for a 1kW EV battery charger is presented with the proper design equations. The constant current/constant voltage (CC/CV) mode control is used to regulate the charging commands to the battery by generating the proper gate sequence to the switches used in proposed PFC converter. The proposed converter is designed and its performance is simulated using MATLAB/Simulink tool with a 48V, 100Ah lead acid battery at the output and the obtained results are shown for the EV battery charging process. The observed results verify that obtained input supply current meets the PQ (Power Quality) limits of an IEC 61000-3-2 standard.
