Comparison of Various Configuration of Wireless Power Transfer System

Abstract

This article deals with mutual comparison of different resonant tank configurations of the wireless power transfer (WPT) systems. Tested compensation configurations are classified as series-series, series-parallel, parallel-series and parallel-parallel and all of them are operated with the input and output frequency converters and other supplementary electronics. As parameter we chose the transfer distance and load. The comparison is made according to changes in overall system efficiency and power delivered to the load along varying both the load and operational distance. All theoretical findings are experimentally verified and discussed in the conclusion section.
