摘要 针对目前无人机的定点降落精度不高,磁耦合谐振式无线电能传输技术在线圈处于非对准的情况下效率会急剧下降。以无线电能传输系统的抗偏移特性为出发点,从耦合线圈的结构和谐振补偿拓扑角度,开展了磁耦合谐振式无线电能传输技术的研究,应用了一种异面重叠的阵列线圈结构的能量传输磁耦合装置。并通过磁通理论分析了该设计结构的可行性,然后通过有限元仿真分析可知,阵列线圈结构的耦合装置使得线圈上方的磁场更加均匀,通过仿真和测试对比在阵列线圈正上方不同位置处的耦合系数,并通过电路仿真在该阵列线圈上方的各种耦合系数下的效率情况,分析可知接收线圈在该阵列线圈上方的耦合系数的变动对整个电路的谐振工作状态造成的影响非常小。搭建的实验系统证明了该系统的恒流输出特性和抗偏移特性。
