Abstract

In this paper, we present a comprehensive dynamic theory for mid-range wireless power transfer (WPT) systems that include three coils (3C- WPTS). We analyze the power transfer efficiency (PTE) in comparison with the corresponding two-coil WPT system (2C-WPTS) and a conventional short-range model of the 3C- WPTS. We study and explore the physical mechanism that enables the radiation suppression in 3C- WPTS. Our theo-retical findings provide insight into possible PTE enhancements for multi-coil WPT over longer distances.
