Analysis Of An Inductive Coupling Wireless Power Transfer System With a Finite Element Method For Charging Application Of Electric Vehicles

Abstract

With the development of technology, Wireless Power Transfer (WPT) systems have also started to be used in charging applications of electric vehicles. The basic methods of WPT systems are based on power transmission systems with laser, microwave, magnetic induction and magnetic resonance. Factors such as the limited use of fossil fuels and environmental pollution have led researchers to see electric vehicles as a solution and to charge these vehicles with wireless systems. Most commercial applications of wireless power transmission are currently limited to close contact transmission distances. There are challenges in increasing coverage, routing transmissions and safely exploiting sufficiently strong electric fields. To provide power efficiently, highly directional transmitters must be applied. Otherwise, with an omnidirectional transmission, only a small part of the transmitted power will reach the receiver. In order to distribute power, especially over long distances, it is often necessary to resort to radiation transfer methods that tightly combine electric and magnetic fields. In this study, important studies on WPT systems were investigated and examined. Then, a WPT transformer is modeled with Finite Element Method based ANSYS-Maxwell-3D. The results obtained using the simulation method are presented in comparison with the research findings. Determining the efficiency of wireless power transfer used in electric vehicle charging applications is the expected result of the study.
