A NOVEL INTEGRATED WIRELESS CHARGING RECEIVER WITH DUAL INVERTER DRIVES FOR EV APPLICATIONS

Abstract

This study presents an advanced wireless charging system for electric vehicle (EV) applications by integrating a Fractional-Order Proportional-Integral-Derivative (FOPID) controller with a dual inverter drive configuration. Wireless Power Transfer (WPT) technology offers a contactless, safe, and convenient alternative to conventional plugin charging; however, it suffers from challenges such as coil misalignment, load variations, and reduced efficiency under dynamic conditions. To overcome these limitations, the proposed system replaces the conventional PI controller with a FOPID controller, which introduces fractional-order tuning parameters for improved flexibility and control precision. The system is modeled and simulated using MATLAB/Simulink with a target output voltage of 360 V suitable for EV battery charging. The dual inverter architecture enhances power handling capability, ensures better load distribution, and improves overall system reliability. Simulation results demonstrate that the proposed system achieves faster dynamic response, reduced overshoot, minimal steady-state error, and significantly lower ripple compared to traditional methods. Additionally, the system exhibits strong robustness against coupling variations and coil misalignment, ensuring stable performance under practical operating conditions. Although the FOPID controller introduces slight computational complexity, its superior adaptability and efficiency make it a promising solution for next-generation wireless EV charging systems.
