Research on the model of magnetic-resonance based wireless energy transfer system

The key of magnetic-resonance based wireless energy transfer technology (MRBWET) is the magnetic coupling system which composed of driving and receiving coils, of which the mathematical model is important to the research of the transmission principle and the optimization of mechanism structure and parameters. Based on calculating the radiation level of typical coil, a magnetic-coupled-coil model was built based on analyzing the magnetic dipole used in the experimental system. According to the model, the quantitative relationship between the power contained in the receiving coil and parameters of resonances was discussed. The optimization method of parameters matching for maximal power transfer is proposed. Simulation and experimental results validate the correction and feasibility of the theoretical analysis.
