Abstract：As a new type of electromagnetic energy transmission technology, EM coupled resonant wireless power transmission technology has been increasingly receiving wide attention from people. In this article based on the system of mutual inductance coupling model, the formula of the transmission efficiency is deduced. and got the relationship between the transmission efficiency of the load and receiving coil distance. The load is divided into pure resistive load, inductive load, capacitive load and they separately discussed the transmission efficiency of the system. Allowing for inductive load and capacitive load transfer’s low efficiency, it proposed the capacity compensation and the inductance compensation method to enhance the transmission efficiency. Finally, the construction of magnetically coupled resonant system experimental platform is verified, which proved the correctness of theoretical analysis. The study of this article, which on magnetically coupled resonance system with different load efficiency, provided a reference for the study of the application of wireless charging electric vehicles.
