This paper proposes the design, simulation and implementation of a wireless power transfer system utilising the concept of inductively coupled power transfer (ICPT). The magnetic structures of the system, the ICPT platform and pick-up, are custom-designed and simulated to enhance power transfer and efficiency through finite-element-method analysis software. Next, the ICPT platform, consisting of a single-layer of rectangular spiral arrays, was implemented on printed-circuit-board and the pick-up was constructed using ferromagnetic material. Overall, the prototype system was shown to induce a relatively uniform low-power across the ICPT platform, to justify the use of such a system in low-power inductive-charging electronics-applications.
