摘要

The increasing integration of renewable energy into electric mobility necessitates efficient power management and robust motor drive systems. This work proposes a Photovoltaic (PV)-fed hybrid energy system for Electric Vehicle (EV) propulsion that combines PV, plug-in AC supply, battery, and supercapacitor storage, all interfaced through a common DC bus to drive a Permanent Magnet Synchronous Motor (PMSM). A Trans-Z-Source Re-Lift Luo (TZS-RL) converter is introduced for high step-up voltage gain, regulated by a Chaotic Black Widow Optimization-tuned PI (CBWO-PI) controller to enhance dynamic voltage response and reduce steady-state error, settling time and overshoot. Vienna rectifier ensures efficient AC–DC conversion with near-unity power factor, while bidirectional converters enable controlled functioning of the hybrid storage system. The PMSM is operated through a closed-loop VSI with PI-based speed control to ensure reliable torque and smooth tracking under dynamic load conditions. Simulation and hardware validation confirm the converter’s capability to boost PV voltage, achieving 96.22% efficiency, minimized component losses, and effective handling of temperature and irradiance variations. Comparative analysis further demonstrates that the CBWO-PI controller outperforms conventional PI and other metaheuristic-based controllers in terms of rise time, overshoot and mean squared error, highlighting the proposed system’s suitability for next-generation EV and smart-grid applications.
