This project presents an enhanced bidirectional wireless power transfer (BWPT) system for electric vehicle (EV) applications, utilizing Particle Swarm Optimization (PSO)-based Sliding Mode Control (SMC) with Phase Shift Modulation (PSM) for superior performance. The BWPT system enables seamless Grid-to-Vehicle (G2V) and Vehicleto-Grid (V2G) operations, addressing key challenges such as power factor management, dynamic efficiency, and power transfer rates. While conventional dual-phase shift Pulse Width Modulation (PWM) techniques improve power factor correction (PFC) in unidirectional wireless power transfer (WPT) systems, bidirectional systems demand advanced control strategies to manage dual-side power converters effectively. The proposed PSO-SMC control framework optimizes the phase shift parameters, ensuring precise power flow regulation, enhanced stability, and reduced switching losses under varying load and grid conditions. Simulation results in MATLAB/Simulink demonstrate that the PSOSMC with PSM significantly improves power factor, transfer efficiency, and overall system reliability, making it a robust solution for future EV charging infrastructure and smart grid integration.
