Abstract

The increasing dependence of electric vehicle (EV) charging systems on conventional grid power results in higher energy costs and grid instability during peak demand periods. To address this, a solar-powered EV charging system using a Landsman DC–DC converter is proposed and its performance is comparatively analyzed against the SEPIC converter under identical operating conditions. The proposed system efficiently converts a variable photovoltaic (PV) input voltage of 17–21 V into a regulated 60 V DC output suitable for EV battery charging. A closed-loop control strategy using a Proportional–Integral (PI) controller ensures stable voltage regulation under varying irradiance conditions. Comparative simulation results carried out in MATLAB/Simulink demonstrate that the Landsman converter achieves significantly lower output voltage ripple (~13 mV), continuous input current, faster settling time (~0.22 s), and higher efficiency compared to the SEPIC converter. These characteristics make the Landsman converter highly suitable for photovoltaic-based EV charging applications. The proposed system provides an efficient, reliable, and sustainable solution for modern EV charging infrastructure using renewable energy sources.
