摘要: 针对多负载谐振耦合式无线输电系统中选择最佳负载个数的实际需求问题,利用电路模型建立了系统总效率和负载个数的理论关系式,在多个接收线圈采用对称式和非对称式的排布方式情况下,定量计算得到系统总效率饱和时对应的最佳负载个数;详细研究线圈半径和传输距离对选择最佳负载个数的影响,分析出最佳负载个数主要决定于线圈半径。最后利用ADS2015搭建了仿真实验平台,验证了理论分析的正确性。

Abstract: In order to remedy the situation of selecting optimal number of load in the multi-load wireless power transmission system via magnetic coupling resonance,the theoretical relationship between the total efficiency of the system and the number of the load is established with circuit model. When symmetric and asymmetric arrangement of multiple coils are took into account,the optimal number of load corresponding to the saturated total efficiency is quantitatively calculated,and the influences of coil radius and transmission distance on the selection of the optimal number of load are investigated in detail. The conclusion for optimal number of load mainly depends on the coil radius is obtained. Finally,the simulation platform is built by ADS 2015 and the correctness of theoretical analysis is verified.
