Modeling of Mutual Inductance between Superconducting Pancake Coils Used in Wireless Power Transfer Systems

Zhanghai Shi, Zhong Cai Qiu

Abstract

This paper examined mutual inductance between rectangular coils and spiral coils used in wireless power transfer (WPT) systems. Half analytical and half numerical method have been adopted. Analysis results show that inductance decreases when misalignment increases. The mutual inductance of spiral coils is smaller than that of rectangular coils with same turns and area.
