摘要无线电能传输系统中能量收发线圈的位置变化直接影响系统的传输特性。本文建立串联-并联（SP）型电磁耦合谐振式无线电能传输系统平台,从电磁场角度出发,分析线圈空间位置与传输系统电感参数的关系,并推导计及线圈空间位置的电感参数计算方法以研究系统的传输特性。通过仿真模拟线圈位移、偏转等条件下系统的运行情况,归纳互感参数与系统传输功率/效率的变化规律和内在联系。搭建实验平台,通过对比实验数据和仿真结果,验证了所提方法的正确性,为无线输电的优化设计提供参考。

Abstract：The characteristics of the wireless power transmission system are impacted directly by the position change of the transmitting and receiving coils. In this paper, wireless power transmission system based on electromagnetic coupling resonant is established in series-parallel (SP) type. The relationship between the space position and inductance of coils in the transmission system is studied from the viewpoint of electromagnetic field. Considering the mutual inductance, the mathematical model is derived to express the transmission characteristics of the system. By simulating the system operation under different conditions such as displacement and deflection of the coils, the varying regularity of the mutual inductance and transmission efficiency is researched. And their internal relation are concluded. The experimental platform is set up and the correctness of the proposed method is proved by comparing the measured data with simulation results, which provides a reference for the optimal design of the system.

Key words： Electromagnetic coupling, wireless power transmission, mutual inductance, coil deflection
