Ferrite Incorporated Wireless Power Transfer Efficiency Improvement Systems

Abstract

Design arrangements for three ferrites integrated substrate surfaced magnetically resonance coupled (MRC) wire-less power transfer (WPT) model is presented. Their layout and simulated results are tested. Ferrite plate and core are incorporated with the proposed wireless power transfer system and achieved the efficiency from 16.6 % to 52 %. For small electronics devices, different ferrite designs and their effect on nearby metallic objects are observed and mitigated. Results show that defined Ferrite configuration is a best solution for confining electromagnetic field and reduce its effects by the foreign materials.
