PV Fed DC-DC SEPIC Converter for EV Charging

Abstract

This paper proposes an Electrical Vehicle (EV) charging using a PV array connected with a DC-DC converter. In that DC-DC converter, the fourth type of DC-DC converter, the SEPIC converter is used. SEPIC converter work as a buck-boost both operations can perform as per required output. The SEPIC converter output is non-inverted and is controlled to take out the maximum power from a Photovoltaic (PV) array to charge the Electric Vehicle battery. The solar PV array is designed of 5759-watt PV modules. The Incremental conductance maximum power point tracking (INC-MPPT) algorithm control of SEPIC converter. It is also used to get the appropriate duty ratio SEPIC converter switch. The proposed system is simulated using the MATLAB/Simulation software. The results of the simulation of battery charging at a constant voltage.
