Resonant inductive coupling as a potential means for wireless power transfer to printed spiral coil

Abstract

This paper proposes an inductive coupled wireless power transfer system that focused on understanding the relationship between induced electromotive force and distance of resonate inductance in printed spiral coils. Resonant frequency is observed experimentally and simulated from the circuit model for proposed receiving and transmitting coils. Simulation result is shown to verify the experimental results. Experimental measurements are in good agreement with simulated result over a range of frequencies that span the resonance.
