Title: Charging Area Extensible Wireless Power Transfer System with an Orthogonal Structure
Abstract: This paper presents a wireless power transfer (WPT) system with an extensible charging area. The proposed system uses a vertical receiver with an 8-shape transmitter. Conventionally, circular coil structures suffer from coupling condition variation when used for dynamic wireless charging applications. In this paper, an 8-shape feeding loop is proposed to construct a directional magnetic field for an orthogonal receiver to receive power efficiently. Furthermore, the transmitter can be extended easily by cascading the transmitter modules. Experimental results have demonstrated a power transfer efficiency of 59% - 70 % when a receiver is moving along a 3-module transmitter array. The proposed structure can be a very good candidate for dynamic WPT applications, especially the charging of moving electric vehicles.
