摘要：
In this paper, a rectangular contactless transformer is proposed to be used in a contactless power supply system. The proposed rectangular contactless transformer maintains a high coupling coefficient even when it has a relatively large air gap. The characteristics of the proposed transformer are compared to a transformer using a general EE core with a variable air gap. The proposed system is verified through simulation and experimental results. The experimental results demonstrate that the efficiency of the contactless power transmission system using a contactless transformer based on a rectangular core is over 20% greater than the system based on the EE core.
