PROJECT TITLE :
Enhanced efficiency for wireless power transmission using an auxiliary loop on ferrite in metallic environment
An enhanced magnetic shield consisting of an auxiliary loop on a ferrite in a metallic environment at half dozen.78 MHz is described. Utilising an in-phase current of the auxiliary loop on the ferrite, the performances such as power transfer efficiency and also the coupling coefficient are improved. The conventional shielding method that uses high-permeability ferrites includes a limitation on the utilisation because of their high magnetic loss tangent. However, the proposed technique using the auxiliary loop coated on the ferrite can give better efficiency than the standard technique. In explicit, at distance of twenty cm, the measured potency is improved by thirtyp.c once applying the auxiliary loop to the ferrite. The proposed technique is taken into account to be useful to wireless power transmission systems having a ground plane.
