基于新型中继模块的高阶无线电能传输系统OA
High-order Wireless Power Transfer system based on a novel relay module
传统三阶宇称时间对称无线电能传输系统为保持宇称时间对称性,只能通过实时调整发射线圈位姿以平衡接收线圈发生空间错位时所引起的耦合系数变化,这往往会对发射线圈与中继线圈之间的气隙空间带来扰动,影响设备的自由部署.为克服该局限性并便于立式设备无线充电,提出一种基于新型中继模块的高阶系统,引入了新的耦合调控策略即通过旋转中继模块实现相邻线圈间耦合系数的平衡,实现了对垂直放置接收端的远距离无线充电,传输效率在强耦合区可以达到85%.
For traditional third-order Parity-Time(PT)symmetric Wireless Power Transfer(WPT)systems,it is necessary to maintain PT symmetry by dynamically adjusting the position and orientation of the transmitting coil to compensate for coupling coefficient variations caused by receiver coil offset.This approach inevitably disturbs the air gap between the transmitting and relay coils,hindering flexible equipment deployment.To overcome this limitation and facilitate wireless charging of vertical equipment,this paper proposes a third-order system based on a novel relay module,which balances the coupling conditions between adjacent coils by rotating the relay module.The proposed system achieves long-distance wireless charging for a vertically placed receiver,with a transmission efficiency of up to 85%in the strong coupling region.
