Simulation of wireless power transfer on electric vehicles charging system.

This paper attempts to provide a detailed simulation approach of a wireless power transfer (WPT) system on Electric Vehicles (EVs) Charging for research and educational purposes. The simulation is based on coupled magnetic resonance technology, which power can be transferred via coupled magnetic resonances in the non-radiative near-field. A simplified power transfer system topology is proposed and implemented. Mathematical analysis and simulation of the proposed charging system is carried out. Based on this topology, the counter-electromotive force (counter EMF, CEMF) in the receiving coil related with constant transfer distance and driving frequency was simulated and analyzed. Through the simulation analysis of the wireless charging system specific design recommendations are provided and significant conclusions are derived. The simulation can be used as a tool for further research on the optimization of WPT for EVs. [ABSTRACT FROM AUTHOR]
