A Review on Wireless Power Transfer Coil Misalignment:Analysis,Effiency Improvement and Positioning

摘要：

　　Coil misalignment often takes place in practical Wireless Power Transfer (WPT) systems,which may cause decrease of transfer efficiency and system instability.This paper analyses coil-misaligned WPT system with theoretical calculation of mutual inductance and transfer efficiency and simulation.Existing ways to improve system efficiency are hereby discussed.Efforts on coil design and impedance network design have demonstrated their feasibility on raising system tolerance with coil misalignment.Current solutions for positioning of WPT coils which could facilitate the parking of Electric Vehicles (EVs) for wireless charging are also presented.
