The endurance of unmanned aerial vehicles (UAVs) is a critical factor in their operational capabilities. One promising approach to extending UAV endurance is through the utilization of wireless power transfer (WPT) technology. Interoperability of UAV wireless charging systems stands as a crucial performance aspect. To enhance interoperability, this paper employs parameter optimization to improve the interoperability of UAV wireless charging systems. Firstly, a circuit model of the LCC-LCC type WPT system is established, yielding the expression for system efficiency. Subsequently, this study investigates the interoperability of the system under different parameters through methods of coupling mechanism optimization and compensation network optimization. Finally, optimized system parameters are obtained through simulation, thereby enhancing the interoperability of UAV wireless charging systems.
