Abstract：In order to determine the influence of electric parameters on the resonant points of magnetic coupling wireless power transfer (MC-WPT) systems, all electric parameters in MC-WPT systems, including the natural frequency of each circuit, mutual inductances and resistances, were comprehensively considered. The MC-WPT system was modeled and analyzed by using complex modal theory, the analytical expressions of resonant frequencies and corresponding output powers of resonant points were accordingly derived. Then the distribution characteristics of resonant frequencies and corresponding powers at resonant points that vary with transfer distance and load resistance were deeply analyzed, and the physical interpretation of frequency splitting was deduced. The analysis results provide a theoretical basis for further study on the optimization and control of resonant points.
