摘　　要：针对一类既需多级输出又能延长传输距离的无线电能传输(WPT)场合,从磁耦合谐振基本原理出发,结合多中继结构与多负载结构的优势,设计了一种新型三线圈双负载WPT系统。该系统选用LCC-Multi-S型补偿拓扑,在传统双线圈系统中加入一级特殊的接收线圈,设计了两级接收线圈结构,推导了系统双负载恒压输出条件,实现了两级负载端的相同功率输出,同时系统WPT距离得到延长。仿真和实验验证了提出的方案的可行性。Aiming at a tyrpe of wireless power transfer(WPT) application that requires multi-level output and can extend the transfer distance,it starts from the basic principle of magnetic coupling resonance,combines the advantages of multi-relay structure and multi-load structure,and designs a new type of three-coil dual-load WPT system.The system selects the LCC-Multi-S type compensation topology,adds a special receiving coil to the traditional dual-coil system,designs the structure of the two-stage receiving coil,and derives the dual-load constant voltage output conditions of the system,and realizes the same power output of the two-stage loads,while the wireless transfer distance of the system is extended.The simulations and experiments verify the feasibility of the proposed cheme.
