Year: 2026
Type: conference-paper
Abstract: Wireless magnetic resonance technology is increasingly central to modern electric vehicle (EV) charging infrastructure, offering cable-free convenience and enhanced safety. Nevertheless, high-power multi-vehicle WPT systems face significant hurdles in maintaining interoperability, efficiency, and robust control. In response, this paper presents a three-phase resonant converter architecture with secondaryside control. The three-phase resonant converter enables highpower handling capability with reduced component stress and improved input current ripple characteristics, while the secondary-side control strategy delegates load regulation to each receiver unit, reducing reliance on a centralized controller. Simulation results demonstrate that the proposed approach improves overall system efficiency and maintains high performance under dynamic alignment and varying load conditions. The proposed approach demonstrates that threephase resonant conversion combined with secondary-side control is a promising and scalable solution for high-power multi-vehicle wireless EV charging.
