Abstract：The characteristics of the wireless power transmission system are impacted directly by the position change of the transmitting and receiving coils. In this paper, wireless power transmission system based on electromagnetic coupling resonant is established in series-parallel (SP) type. The relationship between the space position and inductance of coils in the transmission system is studied from the viewpoint of electromagnetic field. Considering the mutual inductance, the mathematical model is derived to express the transmission characteristics of the system. By simulating the system operation under different conditions such as displacement and deflection of the coils, the varying regularity of the mutual inductance and transmission efficiency is researched. And their internal relation are concluded. The experimental platform is set up and the correctness of the proposed method is proved by comparing the measured data with simulation results, which provides a reference for the optimal design of the system.
