摘　　要：相较于传统有线充电,无线充电对实现UAV自主巡检具有显著优势。该研究提出了一种基于磁耦合谐振原理的高效率UAV无线充电系统。该系统采用LCC-S/P谐振拓扑,并可切换不同的补偿网络以适应阻抗变化;同时,通过设计新型耦合结构来提升能量传输效率。与传统补偿网络相比,该系统在整个充电过程中保持最大效率,并确保载荷平衡和高效传输。经过合理参数设计,搭建的实验样机成功实现了高达68.4 W的充电功率,并达到85.5%的最大充电效率。Compared with traditional wired charging,wireless charging has significant advantages for realizing au-tonomous inspection of UAV.In this study,a high efficiency wireless charging system for UAV based on magnetic cou-pling resonance principle is proposed.The system adopts LCC-S/P resonant topology and can switch different compen-sation networks to adapt to impedance changes.At the same time,the energy transmission efficiency is improved by designing a new coupling structure.Compared with traditional compensation networks,the system maintains maximum efficiency throughout the charging process,and ensures the load balance and efficient transmission.After reasonable parameter design,the experimental prototype built successfully achieved a charging power of up to 68.4 W and a maximum charging efficiency of 85.5%.
