摘要
与传统有线充电相比,无线充电人为干预少,有利于实现无人机的自主巡检,扩大作业半径。在此基于磁感应耦合原理,提出一种适用于无人机的无线充电系统。系统采用LCC-S谐振拓扑,并拥有两个串联且相互解耦的耦合机构。双耦合机构的设计保证了无人机的载荷平衡,易于安装。与单耦合机构的系统相比,所提系统最大效率保持不变,且在整个充电过程中,效率变化较平缓。通过合理参数设计,所搭建的实验样机充电功率达到75.6 W,最大充电效率达到86.3%,且在整个充电过程中,效率仅下降了2.1%。
Compared with traditional wired charging,wireless charging has less human intervention,which is conducive to the autonomous inspection of unmanned aerial vehicle and the expansion of operation radius.Based on the principle of magnetic induction coupling,a wireless charging system for unmanned aerial vehicle is proposed.The system adopts LCC-S resonant topology and has two couplers which are in series and decoupled from each other.Double couplers ensure the load balance of unmanned aerial vehicle and are easy to install.Compared with the single coupler system,the maximum efficiency of the proposed system remains unchanged,and the efficiency changes more smoothly in the whole charging process.Through reasonable parameter design,the charging power of the experimental prototype is 75.6 W,the maximum charging efficiency is 86.3%,and the efficiency is only reduced by 2.1%in whole charging process.
