This paper proposes a three-phase wireless power transfer (WPT) system that addresses efficiency degradation under misalignment by enabling independent current control of each phase coil. The system employs three single-phase power factor correction (PFC) converters and full-bridge inverters for flexible current regulations. A 6 by 6 inductance matrix obtained from finite element method (FEM) analysis is used for modeling, and optimal current sets are derived through numerical iteration. A 22-kW prototype achieves 93.1% peak efficiency, demonstrating enhanced robustness and efficiency compared with conventional symmetric-voltage-based WPT systems.
