| 摘 要： | 针对在磁耦合谐振式无线输电系统中发射线圈和接收线圈之间发生平行不共轴的水平侧移问题,分别采用互感耦合理论和二端口网络理论对其进行建模分析,并通过数学推导得出用s参数表示的归一化功率和传输效率表达式。运用HFSS软件仿真了系统在过耦合、临界耦合和欠耦合状态下,水平侧移量对系统传输性能的影响;提出一种用于改善系统的优化结构。最后,通过实验验证了仿真结果,并验证所提出的优化结构可有效消除侧移所带来的负面影响,改善系统传输效率。

| Abstract: | To study the problem that there is a horizontal sidesway between transfer and receiver coils in magnetic resonance coupling wireless power transfer,the mutual inductance coupling theory and two port network theory is adopting for modeling analysis.The expression of normalized transmission power and transmission efficiency expressed by s parameter by mathematical derivation.The HFSS software is utilized to simulate the impact of the horizontal sidesway on system’s transmission performance under the condition of overcoupling,critical coupling and undercoupling.An optimal structure for improving the system is presented.In the end,the reliability of simulation results is verified by experiment,and the experiment proves that the optimized structure should eliminate the negative effect brought by the sidesway effectively ,and improve the transmission efficiency of the system. |
