摘要感应电能传输（IPT）系统能够实现大功率的高效传输，但当周围的金属体处于磁场中时，高频交变的磁场会在金属体上产生涡流，导致金属体温度升高，具有潜在的危险。电场式

电能传输（CPT）系统不会在金属体上产生涡流，但依然存在极板电压过高、电场辐射范围大等

问题。基于CL拓扑补偿的IPT-CPT结合系统可以解决以上问题，但传统的耦合器都是分开放置，体积较大，且结构松散。因此，本文提出一种集成式耦合器的结构及其设计方法。通过Maxwell

仿真设计集成式耦合器的结构参数和电气参数，使其达到系统要求。最后，通过实验验证了集成

式耦合器的优越性及参数设计方法的正确性，实验系统实现了1kW功率输出，整体效率为88.24%。

本文为感应式和电场式结合系统提供了一种耦合器设计方法，能够有效缩小耦合器体积，同时耦

合器中的极板能够阻隔磁场辐射。

（School of Electrical Engineering Southwest Jiaotong University Chengdu 610031 China）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.
