摘　　要：本文阐述了磁谐振无线电能传输的工作原理,从电路角度对系统进行建模分析。针对磁谐振无线电能传输系统满足最大输出功率时效率比较低的情况,提出以最大功效积为优化函数。针对线圈设计过程中各参数之间的制约关系,提出了在尺寸有限的情况下的PCB线圈优化设计方法。以最大功效积为目标函数,运用理论与仿真分析结合的手段,解决了在尺寸有限的情况下的PCB线圈优化设计问题。最后根据优化结果,制作出一组线圈,并对发射和接收线圈间的互感及交流电阻进行测试,测试结果与理论计算和仿真结果基本一致,验证了所提优化方法的可行性。This paper expounds the working principle of magnetic resonance radio energy transmission, and analyzes the system modeling from the point of view of the circuit. The maximum efficiency product is considered as the optimization function in view of the low efficiency of the magnetic resonance radio energy transmission system to meet the maximum output power. In view of the relationship between the parameters in the coil design process, an optimal design method of the PCB coil with limited size is proposed. Given the maximum efficiency product as the objective function, combining theoretical analysis and simulations, the optimal design of the PCB coil with size limitations is proposed. Finally, a group of coils are constructed based on the optimization results, whose mutual inductance and AC resistances are also tested experimentally. The tested results match well with the calculations and simulations, thus verifying the feasibility of the proposed optimizing method.
