Specialized receivers for three-phase contactless energy transfer desktop applications

open access: yes2007 European Conference on Power Electronics and Applications, 2007
In this paper, a new contactless energy transfer (CET) desktop application is presented. The CET desktop uses a matrix of hexagon spiral windings embedded underneath its surface, to transfer power to CET enabled consumer electronics devices placed on the table. To improve efficiency and limit stray magnetic fields, clusters of only three primary coils,
