DYNAMIC MODELING AND CALCULATION OF SELF AND MUTUAL INDUCTANCE BETWEEN A PAIR OF COILS FOR WIRELESS POWER TRANSFER APPLICATIONS USING ANSYS MAXWELL

Abstract: In this paper an in depth analysis of modeling and simulation of a two coil wireless power transfer system consisting of Transmitter coil and Receiver coil separated over a distance is described in detail using industry standard ANSYS Maxwell simulation tool. Where in dynamic calculation of self and mutual inductance of the coils is computed by assigning distance between the two coils as an variable, "dist" which is used for sweeping analysis, which makes the analysis simpler and increases the computational speed of the self and mutual inductance calculations. It is also proved that as the distance between the Transmitter and Receiver coils increases the Mutual Inductance coupling decreases and vice versa.
