Frequency Splitting Characteristics of Nonlinear Resonant WPT System
In order to suppress the frequency splitting phenomenon of the wireless power transmission system,a Non-linear wireless power transmission system was used to solve the described issue.This method incorporated a non-linear inductor into the secondary coil and used the saturation characteristics of the nonlinear inductor to affect the system transmission efficiency.The equation for the transmission efficiency of nonlinear systems was derived,and the principle of the method was described.The method was simulated and experimented,and the correctness of the simu-lation results was verified by experiments,the results show that the nonlinear transmission system has an obvious effect in limiting the frequency splitting phenomenon.
