A proposed optimized solution for wireless power transfer using magnetic resonance coupling

Abstract

In this modern system, power is part of our lives. These days power is being transmitted through wires and it has some limitations like in medical area or in robotics because it's difficult to be connected with wires all the time. Rechargeable batteries are also not feasible solution because they needed to be charged regularly and also carry some weight and space. In medical area pacemakers and defibrillators need to be installed inside human skin and required to replace their batteries after specific interval of time. But using wireless power transfer we can charger their batteries without cutting skin. Wireless power transfer (WPT) is under development technology these days. Researchers have developed many techniques to transfer power without wires but recently MIT researcher's demonstration got attention when they transmitted 60W over a distance of two meters using WPT magnetic resonance technique but the efficiency and range remained serious problem. This paper will describe optimized model of maximum wireless power transfer and also way to increase the range between transmitting and receiving coil.
