Wireless Power Transmission

Abstract

The idea of Wireless Power Transmission was given by Nicola Tesla as he was keenly interested in lighting the world from his AC generation and transports the power without wire worldwide. Wireless power transmission (WPT) is a very useful technology in near future and can be very much effective. There are two kinds of WPT technologies: near field technique and far field technique. Near field-technique uses inductive coupling, resonance inductive coupling and air ionization. Far-field techniques can be achieved through microwave power transmission and LASER power transmission. However, the efficiency is low as of now and researchers have progressed less in this field to materialize the commercial technology and still in different areas of world researches are still going on over WPT. Thus, we have covered the possible ways to harness the power without wires from many research carried out so far and we have used ferrite rod which increased the efficiency of the output. The advantages, disadvantages, biological impacts and its applications are presented along with all the work done by us and the output.
