Abstract: Wireless power transmission is still in its infancy as a topic. Although devices and applications have been designed that transmit power over short distances, their price and design complexity keep them out of the reach of ordinary users. There is a need for a simple, efficient and cost-effective system which can create the changing electromagnetic field required to initiate wireless power transfer.Wireless power transfer is a challenging task because very few people till now have ever been able to perform it efficiently at distances longer than few meters and then to only with a very low amount of power. At present also no one has been able to implement long distance wireless power transfer (exceeding 2meters) in our commercial and domestic applications, such as in our own homes to light a lamp / LED / fans without the actual hard cored wiring. The area of my research proposes in developing a wireless power transfer system (a simulation model with a appropriate tool or a prototype model) that is targeted at delivering enough power to light a lamp or LED / or switch ON the fan in our homes using the principle of resonance induction, coming under the category of middle distance wireless power transmission mode. There are many applications that would also benefit from the ability to transfer power wirelessly( even at low wattage ) such as charging a laptop, personal computer and cell phone ; for the appropriate technology must be developed to satisfy these applications.
