[Abstract]:In the practical application of magnetic resonance mode wireless power supply system, the output voltage is usually required to keep constant. In order to improve the stability of transmission power, it is also necessary to maintain the constant operating frequency of the system. In this paper, the transmission coils are used as parallel compensation, the receiving coils and resonance coils are all compensated in series, and the magnetic resonance mode wireless power supply system is studied. Based on the mutual inductance model, the constant current of the transmitting coils of the system is given. The parameter boundary condition of the output voltage constant voltage can ensure that the system can still be in constant voltage state under the condition that the controller is not needed and the distance between the loops is not changed by the constant frequency drive. Simulation and experiments show that the proposed method has good constant voltage characteristics.
