Comprehensive mathematical modelling and experimental analysis of a wireless power transfer system for neighborhood electric vehicles

Research on developing the applications of Wireless Power Transfer System (WPTS) has increased considerably during last few years. Due to functional and environmental benefits, charging of electric vehicles via WPTS has been contemplated in academic and industrial research. The WPTS based on Magnetic Resonant Coupling Technique (MRCT) is considered as an efficient way for contactless power transfer over medium distances (up to about 20 to 30 centimeters). This paper presents a comprehensive MATLAB/SIMULINK based model for such a system. The parameters of the model are derived from mathematical equations presented in the paper. The performance of the model is also verified experimentally. Performance parameters, like power transfer efficiency and loss factor have been shown.
