Electric vehicles are seen as an alternative option in response to the depletion of resources. In order to increase the use of EVs in daily life, practical and reliable methods to charge batteries of EVs are quite important, accordingly wireless power transfer (WPT) is considered as a solution to charge batteries. In this study, a system which has 1 kW power rating and 20 kHz operation frequency is designed and implemented. Finite Element Analysis (FEA) simulation that verifies the coil design and inductance calculation has been carried out by using ANSYS Maxwell software. Waveforms of power parameters are obtained. Power loss at each stage and the efficiency of overall system are determined and interpreted.
