无线电能传输中继线圈位置特性分析OA
Analysis of the Position Characteristics of Wireless Power Transmission with Relay Coils
增加中继线圈是提升无线电能传输系统性能的一种有效方法,但目前关于中继线圈位置的确定多数还是采用均分距离或经验选定.为了阐明中继线圈对系统性能影响的机理,基于二端口网路理论比较了典型两线圈耦合机构和中继式耦合机构的端口阻抗区别,采用有限元模型的动态扫频分析,总结了中继线圈相对位置变化对互感的影响规律,通过实验测试,验证了中继线圈相对空间位置对系统性能的影响,证明了理论和仿真分析的正确性.针对中继线圈位置特性的研究,对中继式无线电能传输系统的优化设计有一定的参考意义.
Relay coil is an effective method to improve the performance of wireless power transmission.But the selection of relay coil position is usually based on experience.To elucidate the mechanism of the impact of relay coils on system performance,the port impedance differences between typical two-coil and relay-type coupling mechanisms were compared.The dynamic sweep analysis was used to summarize the influence of relative position on mutual inductance.Experiments was conducted.The impact of relative spatial position of relay coils on system performance was verified,as well as the correctness of theoretical and simulation analysis.The research on the position characteristics of relay coils has some reference significance for the optimization design of relay-type wireless power transmission.
