Geometry Based Optimization For Inductively Coupled Spiral Coils



Authors : Sadi Yassin .

Abstract

Efficiency of inductive linking is an essential part in wireless power transfer WPT. In this paper, we propose an optimization to increase the efficiency of the system and reduce the size of coupled spiral coils implementable microelectronic devices based on geometrical characteristics. Moreover, an elimination of the splitting frequencies is achieved. The proposed approach provides much better results comparing error rates between the optimal mutual inductance and the mutual inductance obtained using calculated geometrical parameters of coils.

Keywords

mutual inductance; wireless power transfer; transfer coefficient; Transfer efficiency.
