摘要：
This paper deals with the shielding of the magnetic field generated by two planar coils of a wireless power transfer (WPT) system at the frequency of tens of kilohertz used in automotive applications. Different shielding techniques using conductive and magnetic materials are examined and discussed highlighting strong and weak points of each other. Finally, the proposed shielding configuration consisting of a combined conductive and magnetic material is applied to model an electric vehicle equipped with a WPT charging system. With this configuration, compliance with the electromagnetic field safety standards can be achieved inside (passengers) or near (pedestrian) the car.
