Modeling of an inductive link for wireless power applications

This paper presents a model of an inductive link to estimate its power efficiency and voltage gain, which is essential to the design of an inductive link that can transmit the maximum amount of power or optimize a system within the constraints of the application. The proposed model does the prediction using the geometric variables of an inductive link. An inductive power link was implemented, and the accuracy of the proposed model was confirmed by comparing the measured and calculated results. This model can also suggest the optimal operating frequency and load of an inductive link for maximal power transfer.
