In order to explore the wireless power transmission mechanism via magnetic coupling resonance,by using the coupled mode theory,the mathematical model of the magnetic coupling resonant wireless power transmission system is established,and the calculation model of the system energy is obtained. For the further analysis of the relationship between the electromagnetic energy,coil natural loss and coupling coefficient,this paper provides a theoretical basis for the design of the system. Maxwell is used to simulate the electromagnetic energy transmission of electromagnetic energy in the resonant state,and the mode of energy transfer in the resonant state is drawn. The correctness of the theoretical analysis is verified. Finally,a small power magnetic coupling resonant wireless power transmission experiment platform is built. Meanwhile,the transmission characteristics are analyzed,and the experimental results show that the provided system can satisfy the power demands of the low power equipment,which provides a practical basis for the application of the radio transmission system.
