Abstract

Wireless power transfer is an emerging technology due to its wide applications in wireless charging of electric vehicles, implanted medical devices, etc. To make wireless power transfer more efficient and user-friendly, the designer must know its implementation's extremes. One crucial part of the above need is the proper design of a high-frequency transformer in the wireless power transfer system. This high-frequency transformer uses the inductive power transfer principle to achieve minimum losses during power transfer. This paper presents the design of a high-frequency transformer intended for electrical vehicle charging. In this design, various configurations of transformer with different distances between primary and secondary coils have been analysed for wireless power transfer parameters such as coupling coefficient and mutual inductance. The designs have been simulated using ANSYS Maxwell software, and the results are presented. Finally, this work also compares circular and rectangular type transformer designs in terms of wireless power transfer.
