Coupling coil is considered as the core link of the wireless power transmission system, and the optimal design of coupling coil the has a direct impact on the transmission efficiency and power of the whole wireless power transmission system. In this paper, we utilized ADS software to build a typical wireless power circuit based on the equivalent circuit model of the prototype system to simulate the energy transfer process and analyze the system transmission efficiency and power output which reduced the computational complexity and simplified the coil design process. In order to implement the optimized coupling coil of the wireless transmission system, coupling coil parameters are calculated to the determine the optimal resonant capacitance compensation, coupling coefficient, and radius of coil by the establishment of simulation model of circuit. The equivalent circuit model of the system has the wide applicability. The simulation results show that the design method can improve the transmission performance optimization of the magnetically coupled resonant wireless power transmission system.
