摘要针对耦合磁共振电能传输(CMRPT)系统功率传输和效率优化问题, 建立系统的详细等效互感模型, 对系统的磁路机构进行优化设计:分析了在不同能量线圈与负载线圈的间距下, 两个辅助共振线圈与能量线圈和负载线圈之间的位置比例关系对系统功率传输特性的影响, 同时对负载电阻、工作频率等参数进行了优化选取。分析结果发现, 对于能量线圈与负载线圈位置一定的耦合磁共振电能传输系统, 通过对两个辅助线圈的位置进行优化配置, 可以有效地提高系统的功率传输能力或者效率。这个结论有效地减少了实际系统磁路设计的盲目性。最后, 通过实验验证了理论分析的正确性。

Abstract：In order to optimize the power transfer capability and efficiency of coupled magnetic resonances power transfer (CMRPT) system, the mutual inductance mode of the system is established in this paper, and the magnetic circuit is optimized: with different distance between the power coil and the load coil, the relation between the distance proportional of the two auxiliary resonant coils to the power coil and the load coil and transmission power and efficiency are analyzed, and the parameters such as the load resistance and the frequency are also optimized at the same time. The results show that for a CMRPT system with a certain distance between the power coil and the load coil, by optimizing the location of the two auxiliary resonant coils, it can effectively improve the system’s power transfer capability or efficiency, the conclusion effectively reduces blindness for an actual circuit system design. Finally, the theoretical research is justified via an experiment.
