ELECTROMAGNETIC INDUCTION TECHNIQUE OF WIRELESS POWER TRANSFER FOR UNIVERSAL WIRELESS CHARGING DEVICE

Abstract: With the constant and increase growth in technological advancements, technical know-how and innovations, keeping up with the trends becomes the order of the day, most technological advancement aim at further improving our way of life and/or providing new and easier ways to solve a general problem, with so many examples to site, like the invention of smart home security systems, smart baby monitors, self-driven cars, digital voting systems etc, wireless power transfer seems to be at the very top of this list. The main objective of wireless power transfer is to eliminate damage of mobile phone USB port and make the transfer of power from sources to devices more convenient and seamless. Wireless charging of gadgets is one of the new emerging technologies in the world at the moment. The most common method used at the moment is wireless power transfer by inductive coupling. Wireless power transfer is one of the simplest and cheapest ways of charging as it eliminates the use of conventional copper cables and current carrying wires. The research 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 used since currently it’s the easiest method of wireless power transfer because of high efficiency and large amount of the energy transferred. In this project report, results of experiments done to check wireless power transfer will be discussed. Also, to further show its versatility and range of applications the power transferred will be used to charge small and medium devices with emphasis on mobile phones with the aid of additional circuitry; and also study the effect of placing hurdles between the transmitter and receiver so as to establish if it is an alternative in the medical industry for charging pace makers.
