Design of high axial-to-radial ratio multi-coil magnetic coupling mechanism

This study presents a multi-coil wireless power transfer (WPT) system based on magnetic coupling resonance, employing an innovative four-layer eight-coil compensation topology. The proposed configuration achieves decoupling between same-side coils through a hierarchical series resonant network. The research optimizes the selection of high-frequency magnetic cores and Litz wires to minimize power losses, while systematically validating the system's power transmission performance under dynamic operating conditions through comprehensive simulations and experimental tests.
