摘　　要：为解决传统多负载感应耦合电能传输(inductively coupled power transfer,ICPT)系统存在的问题,提出一种新型多负载变拓扑感应耦合电能传输系统。该新型ICPT系统主要采用可变拓扑的高频逆变器,通过检测负载信息,系统可根据任一时刻供电负载的数量,自动改变逆变器工作结构,只让需要供电的负载所对应的原边线圈处于工作状态,从而基于"点对点"模式实现负载高效无线供电。仿真与实验验证了该新型多负载变拓扑感应耦合电能传输系统的可行性,对桌面多负载无线供电领域的设计与应用有着广泛的应用指导意义。To solve the problems existing in the conventional inductively coupled power transfer（ICPT） for multi-load, a novel topology-variable inductively coupled power transfer system for multi-load was put forward, which mainly has adopted a topology-variable high-frequency inverter. Through detecting load information, according to the number of loads at a given time, the novel ICPT system can change the working structure of inverter automatically, and keep the primary side coils corresponding to the loads in working status. So the novel ICPT system can transfer power to the loads respectively based on ＂peer-to-peer＂ wireless power supply. Simulations and experiments have been built to verify the feasibility of the novel ICPT system, and the novel ICPT system plays a certain guiding role in the field of desktop multi-load wireless power supply system.
