STUDY OF WIRELESS ENERGY TRANSMISSION

This article deals with the perception of communicating power without cables. A recent trend in power supply design is the development of charging systems that are capable of wireless power transfer. In this the charging device is not connected to the power supply. Various technology are available for wireless transmission of electricity. The new technology for wireless energy transmission is the resonance inductive coupling. With the help of this technology energy is transferred to the middle distances. In this technology we use two coils ,one is the transmitting coil and other is the receiving coil. An alternating current is passed through the transmitting coil and generates the magnetic field , due to this voltage is induced in the receiver coil. This can be used to power devices. In this paper we discussed the phenomenon of wireless energy transfer, its applications, advantages and disadvantages.
