Devised Technology for Wireless Power Transmission

Wireless charging of gadgets is one of the most emerging technologies in the world today. The most common method currently used is wireless power transfer through inductive coupling. Wireless power transfer is one of the simplest and cost-effective ways of charging, as it eliminates the need for conventional copper cables and current-carrying wires. In this paper, a methodology and principle of operation are devised for wireless power transfer through inductive coupling, and a feasible design is modeled accordingly. The inductive coupling technique is chosen because it is currently the easiest method of wireless power transfer, offering high efficiency and the ability to transfer a large amount of energy. This paper presents the results of experiments conducted to verify the wireless power transfer functionality. Additionally, to demonstrate its versatility and range of applications, the transferred power is used to charge a battery with the aid of additional circuitry. We also study the effect of placing obstacles between the transmitter and receiver to determine its potential as an alternative in the medical industry, such as for charging pacemakers. This research focuses on the study of wireless power transfer for the purpose of transferring energy at maximum efficiency within a small range or in the near-field region.
