The rising popularity of electric vehicles (EVs) has sparked an urgent need for greener, more efficient charging networks. Linking solar power directly to grid-tied charging stations is a smart strategy to ease the burden on the electrical grid while lowering carbon footprints. The main hurdle, however, is that solar panels naturally produce a low and fluctuating DC voltage, demanding power converters that can significantly boost and stabilize the electrical output.This paper presents the design and control of a high-gain, boost-integrated Luo DC-DC converter built specifically for grid-tied, solar-powered EV chargers. By blending standard boost and Luo converter architectures, this setup achieves superior voltage amplification, reduces current ripple, and limits energy loss. To keep the voltage steady despite changing weather and shifting loads, we implemented a Proportional-Integral (PI) controller finely tuned via Particle Swarm Optimization (PSO). We also incorporated a battery storage unit to act as a reliable backup. Finally, the smoothed DC power is fed into the main utility grid utilizing a single-phase voltage-source inverter paired with an LC filter network.MATLAB/Simulink testing confirmed the system's robust performance, showcasing tight voltage control, quick adaptability, and excellent power conversion efficiency
