A Rotation Face to Face Through-hole Wireless Power Transfer System Liangyu Bai, Jianquan Zhang, Yanmin Liu

Abstract

Contactless slip-ring provide a safe, non-contact, high efficiency, wear-free and reliable power transfer solution with low maintenance for rotary applications. In this paper, a novel magnetic coupler of wireless power transfer (WPT) system is designed. Compared with the traditional slip ring power supply, it can be applied to the rotating condition. To realize light-weight and small-volume of the WPT, the magnetic coupler and circuit have been optimized from both compensation topology and coil configuration. Experimental results are demonstrating that transfer power is 280W at efficiency of 91.7%.
