  • To achieve the output control of CLC type contactless power transfer (CPT) systems, a system model was built using the discrete time mapping method, and an analytic expression of periodic fixed points was given. On this basis, a soft-switching frequency computing method and an output power calculation method at different frequencies were developed. An output power control method based on average power balance was proposed, and then verified experimentally. The results show that the combined control at different frequency operating points can switch the output voltage between 20 and 50 V in maximum 41 ms to satisfy different load requirements, and the switching devices operate in the soft-switching state.
