ABSTRACT This research investigates the efficiency enhancement of dynamic electric vehicle (EV) charging systems by integrating novel resonant coupling-based wireless power transfer (WPT) techniques. Dynamic charging enables EVs to replenish energy while in motion, mitigating range anxiety and reducing reliance on large battery capacities. However, conventional inductive charging systems face limitations in efficiency due to misalignment, high transmission losses, electromagnetic interference and durability concerns under dynamic roadway conditions. To address these challenges, the proposed approach leverages optimized resonant coupling topologies, adaptive frequency tuning, and impedance matching strategies to maximize power transfer under varying operational conditions. The study includes the design and simulation of advanced coil configurations, utilization of multi-layer magnetic pads, and implementation of intelligent control algorithms capable of real-time load modulation. Comparative performance analysis with traditional inductive and capacitive WPT methods demonstrates substantial improvements in overall transfer efficiency, stability, and tolerance to positional deviations. The experimental validation, conducted on scaled prototypes under simulated roadway conditions, indicates efficiency gains exceeding 15%, along with reduced system losses and improved coupling robustness. This enhancement significantly contributes to extending EV operational ranges, reducing infrastructure costs per unit energy, and improving grid integration feasibility. The outcomes of this research are expected to accelerate the deployment of dynamic wireless charging infrastructure, foster greater adoption of EV technology, and support sustainable urban mobility initiatives worldwide. The proposed resonant coupling WPT framework represents a scalable, cost-effective, and high-performance solution for next-generation EV charging networks, paving the way for a future with seamless, in-motion energy replenishment. |
