According to wireless power transmission system with dual relays, the mutual inductance coupling theory is adopting for modeling analysis. Through the combination of theory and simulation methods, the relationships between transmission efficiency and the coupling coefficient, turns of receiving coils are further analyzed. At the same time, the optimized design of coils' turns at different transmitting distances under the concrete transmission system is discussed. It provides theoretical basis for the design of wireless power transmission system and its optimized method of efficiency. In order to verify the correctness of theory, the experiment system with same parameters of the simulation system is designed. The correctness of the theoretical analysis is better verified, that is, for determined wireless power transmission system, there is a unique coil turns to make the transmission efficiency maximized.
