[Abstract]:A novel coil self-inductance identification method based on least square method is proposed in this paper. The nonlinear high-order differential equation and the data matrix of a voltage-type wireless energy transmission (charging) system connected in series between the transmitter and receiver are established. The process parameter vector of the system is obtained by the least square method, and the self-inductance identification problem of the coil is transformed into the system parameter identification problem. The self-inductance identification of the transmitter and receiver coils of the wireless charging system is completed. Finally, the simulation and experiment are carried out. The feasibility of the method is verified.
