摘要:

为解决基于宇称时间(PT)对称原理的串联-串联(S-S)补偿原始无线电能传输(WPT)系统PT对称区域受限的问题,采用基于PT对称原理的S-PS拓扑多负载补偿系统,扩大系统高效工作的范围,通过引入合适的电容分配比可使输出功率提高50%;设计的磁耦合器实现2个接收线圈之间的解耦,解决其耦合干扰问题。仿真验证拓扑电路的有效性,磁耦合器在偏移条件下解耦条件依旧成立。

Abstract:

In order to solve the problem of the limitation of the PT symmetry region of the original WPT system based on the symmetry principle of the PT symmetry principle S-S,the S-PS topology multiload compensation system based on the PT symmetry principle is adopted.The efficient working range of the system is expanded,and the output power is increased by 50% with the proper capacitance distribution ratio.The magnetic coupler is designed to realize the decoupling between the two receiving coils,which solves the coupling interference problem between the two receiving coils.Simulations verify the effectiveness of the topological circuit,and the decoupling condition of the magnetic coupler is still available under the offset condition.

Key words: parity-time(PT) symmetry, wireless power transmission, coil decoupling, multiple loads, S-PS topology
