An Optimal Design of Resonant Coil for Magnetically Coupled Resonant Wireless Power Transfer System

By the coupled mode theory,the conditions of efficient energy transfer between the wireless power transfer system for transmitting and receiving coils was derived,then the coil of coupled magnetic resonances analyzed using the equivalent circuit model,and the relationship of the transmission efficiency and the coil parameters got by control variable method through MATLAB.It provides the basis for the optimal design of the coupling coil.Finally,optimization of a specific model was introduced in this paper,with the hope that it will help to achieve an efficient and optimized model.
