Abstract :
In this paper, an equivalent circuit model of a multilayer planar winding array structure that can be used as a universal contactless battery charging platform is presented. This model includes the mutual-inductive effects of partial overlaps of planar windings in the multilayer structure. It has been successfully simulated with PSpice and practically verified with measurements obtained from three prototypes. This circuit model forms the basis of an overall system model of the planar charging platform. It is demonstrated that model parameters can be derived from the geometry of the winding structure. Errors between the calculated and the measured results are found to be within a tolerance of 5%
