Maximum Power Point Tracking of Inductive Resonant Wireless Power Transfer Systems Using a Buck Converter on the Receiving Side to Mitigate the Effects of Coil Misalignment

Abstract

The purpose of this paper is to show the results obtained by performing maximum power transfer in inductive resonant wireless power transfer (WPT) systems. The research highlights the importance of power electronic systems on the receiving side of a WPT system. Before getting into the specifics of the research, a fundamental theoretical analysis about WPT systems is performed followed by an LTSpice simulation setup and results. The results presented show that power electronic DC/DC converters can be successfully used to increase the amount of wirelessly delivered power through impedance matching.
