High-Ratio Quadratic Boost Converter with Voltage Lift and Voltage Doubler Techniques for Photovoltaic Powered EV Charging

Abstract

The rapid growth of electric vehicles (EVs) demands reliable charging infrastructure that aligns with sustainable energy sources. Photovoltaic (PV) systems are a promising candidate; however, their fluctuating and relatively low direct current (DC) voltage output requires effective conversion to meet EV charging standards. This study proposes a high ratio quadratic boost converter (QBC) integrated with voltage lift and voltage doubler techniques to enhance voltage gain, combined with a Proportional Integral Derivative (PID) controller for output stabilization. The converter was modeled and simulated in MATLAB/Simulink with PV modules as the power source under varying solar irradiance conditions. Simulation results show that the proposed topology achieved an output voltage of up to 450 V, suitable for EV charging, while the PID controller significantly reduced voltage ripple and improved transient performance, including time rise and settling time. These findings demonstrate that the proposed converter topology offers a stable, efficient, and scalable solution for photovoltaic-powered EV charging systems.
