Abstract: Wireless Inductive Power Transfer System (WIPTS) for electric vehicle battery charging is an emerging technology. It enables electric power transmission without any physical connection between the transmitter coil (Tx) and receiver coil (Rx) over a certain distance. However, the power transfer capability between the wirelessly coupled inductive coils is greatly affected by mutual inductance (MI) between them. This paper presents a new analytical method based on Neumann's equation for computation of MI between the asymmetrical spiral circular coupled coils. The computed mutual inductances are validated with Finite Element Modeling (ANSYS MAXWELL) simulation results. The relative error between the analytical and FEM simulated results is negligible. © 2020 IEEE.
