Abstract An inductive power transmission system can transmit high-power effectively. But when the surrounding metal objects in the magnetic field, the high-frequency magnetic field will produce eddy current on it, which has potential danger for the risen temperature. Capacitive power transfer system doesn’t produce eddy current. But, there are still problems such as high plate voltage and electric field radiation. The inductive and capacitive combined system based on CL topology compensation can solve the above problems, but the traditional coupler bodies are usually placed separately, which’s volume is large, and the structure is loose. Therefore, the integrated coupler and its design method were proposed in this paper. This paper designed structural parameters and electrical parameters of the integrated coupler through Maxwell simulation to meet system requirements. Finally, the experiment verified the superiority of integrated coupler and the correctness of parameter design method. The experimental system achieved a power output of 1kW, and the overall efficiency was 88.24%. This paper provides a coupler design method for inductive and capacitive combined system, which can reduce the volume of the coupler. At the same time, the plates can block the magnetic field radiation.

Key words： Wireless power transfer inductive and capacitive combined system integrated coupler CL-composed topology
