摘　　要：在双负载无线电能传输系统中,副边线圈之间的耦合干扰问题成为制约系统性能的重要因素。为此,提出一种单发射-双接收磁耦合机构,旨在解决两个副边线圈之间的耦合干扰问题,并通过原边线圈的设计实现两个负载获得相同的能量输出。在不采用屏蔽材料和控制方法的情况下,该机构仅通过线圈结构设计即可实现两个副边线圈的完全解耦。实验结果表明,采用该机构的无线电能传输系统在双负载情况下,两负载互不影响且系统能量传输效率可达88.7%。In a double-load wireless power transfer(WPT)system,the problem of coupling interference between secondary-side coils becomes a critical factor that seriously limits the system performance.To solve this problem,a singletransmitter dual-receiver magnetic coupling mechanism is proposed,which aims to solve the problem of coupling interference between two secondary-side coils.In addition,the same power output for both loads is achieved through the design of the primary-side coil.Without using shielding materials or control methods,this mechanism can achieve complete decoupling of two secondary-side coils only through the design of coil structure.Experimental results show that the energy transfer efficiency of the WPT system with this mechanism can achieve 88.7%under double-load.Moreover,the two loads can operate independently with no interference.
