Design of a wireless power transfer system for EV application based on finite element analysis and MATLAB simulation

Wireless power transfer (WPT) has been a very popular topic of research recently. In most research the coil design is based on the classical theory and the parameters of the coils are obtained by calculations or direct measurements. However, the method has its limitation when the shape and structure of the coil is complex or the coil hasn´t been constructed. The purpose of this paper is to present the whole process of designing coils and building a wireless power transfer system with the finite element analysis (FEA) and with MATLAB simulation in detail. Finally the experimental results will be presented to verify the validity and reasonability of the design method.
