Optimization Design for Disc Resonators of a Wireless Power Transmission System

无线电能传输系统在给定工作频率下,发射和接收线圈间的互感、等效内阻以及负载阻抗是影响系统传输效率的主要因素。针对线圈设计过程中各参数之间的特性和相互约束关系,提出一种在给定工作频率、传输距离下的盘式谐振器的优化与设计方法。该方法综合考虑谐振频率、线圈半径、匝数等因素,以传输效率为优化目标,解决了特定条件下的具体谐振器设计问题。实验结果与解析、仿真结果具有较好的一致性,验证了该方法的正确性和有效性。

Under the given frequency condition, the main influence factors of transmission efficiency of the wireless power transfer system are mutual inductance between the transmitting and receiving coils, equivalent resistance of coils and the load impedance. In the coil design process the characteristics and constraint relationship of variable parameters are considered, and then an optimal design method of disc resonators with the given frequency and transmission distance is proposed. With the transmission efficiency as the optimization objective, this method considers resonant frequency, the radius and turns of coils, and other factors, which solves the specific resonator design problem under the certain conditions. Experimental results are well consistent with simulation analysis, which show the effectiveness and correctness of the proposed method.
