- Abstract:
-
Due to the problems of non-contact ICPT, such as device aging, temperature change, load change, etc., the resonant frequency of the system will change, which will affect the realization of the zero-voltage switch (ZVS) and the power transmission capacity of the system. Taking the parallel resonant contactless power supply platform as the research object, the novel method of controlling the nonlinear variable inductance control frequency by double closed-loop control loop is adopted, and the stable control of the contactless power supply platform at the given resonant frequency is realized through the ingenious selection of circuit parameters. Both theoretical derivation and experimental results confirm the feasibility of the scheme.
