Integration of Solar Panel and KY Converter for Sustainable Electric Vehicle Charging Application

Abstract

As the shift toward eco-friendly transportation accelerates, there is a growing demand for integrating renewable energy sources into electric vehicle (EV) charging systems. This study proposes a solar-powered EV charging framework that employs an enhanced KY converter to efficiently manage the intermittent nature of photovoltaic (PV) energy. Its notable advantages—such as low voltage ripple, rapid transient response, and high operational efficiency—make it more effective than traditional DC-DC converters in renewable energy applications.To further strengthen voltage regulation, a proportional-integral (PI) controller is implemented, allowing real-time tuning of the converter’s duty cycle in response to changes in solar irradiance. This feedback-based control system ensures consistent DC link voltage and enhances the overall reliability and responsiveness of the setup. MATLAB Simulation analyses validate that the system effectively maintains voltage stability and promotes efficient energy utilization under dynamic environmental conditions.This approach offers a practical and sustainable pathway for clean energy integration into the transportation sector. The combination of solar PV technology with KY converter-based power control demonstrates a scalable model for future smart EV charging infrastructure aligned with global sustainability goals.
