摘要无线电能传输在现代生活和科技中都有广泛的应用。文从演示实验角度出发,设计了不同负载的次级线圈。探究了初级线圈和次级线圈相关特性,从实验上找到了初次级线圈的共振频率ｆ＝(２１３８±８)Ｈｚ。基于该共振从实验上测量了不同负载电阻下其输出功率与传输效率。在１００ Ω 左右效果最优。进一步选择负载电阻１００ Ω,探究了两个特征位置输出功率的变化,在初级线圈内,次级线圈越靠近边界输出功率越大,在竖直中心轴方向,得到了功率下降到３６.８％时的距离为(５９.８±０.９)ｍｍ。基于以上参数,设计了四种演示形式的负载。

Abstract: Wireless power transmission has wide applications in modem life and technology. From theperspective of demonstration experiments, this paper designs secondary coils with different loads.It explores therelevant characteristics of primary and secondary coils, and experimentally finds the resonant frequency of theprimary and secondary coils to be f= (21388) Hz.Based on this resonance, the output power and transmissionefficiency under different load resistances are measured experimentally. The optimal effect is achieved at around1000. Further selecting a load resistance of 1000,the variation of output power at two characteristic positionsis explored. Within the primary coil, the closer the secondary coil is to the boundary, the greater the outputpower. In the vertical central axis direction, the distance at which the power drops to 36.8% is found to be(59.80.9) mm. Based on the research of the above parameters, four types of demonstration loads are designed.

Key words: wireless power transmission resonant frequency primary coil secondary coil output power
