Design Optimization of Coupling Mechanism for Magnetic-Resonance based Wireless Power Transfer System

Through the circuit model of the magnetically resonant wireless power transfer system consisting of four coils, the expression of the transmission efficiency is obtained. First, use a two-coil model in a preliminary design of the parameters to determine the transmission distance and resonant frequency and to obtain the radius, number of turns and wire diameter of the resonance coil. Then, use the four-coil model to optimize the parameters and adjust the mutual inductance between coils to achieve the maximum transmission efficiency of the system. Combination of the two-coil model and the four-coil model for design and analysis of the system parameters ensures the model analysis accuracy and simplifies the resonant coil design process, thus providing a theoretical basis for design optimization of the magnetically resonant wireless power transfer system.
