Optimization of Contactless Energy Transfer System Adaptive to Changes in Coil Separation

The presented paper has the concept of transmission of electrical power without the use of any kind of electrical conductors, cables or wires. The main aim of this research work is to give an clear view of recent researches and development in the field of wireless power transmission. This paper has also has history related to the WPT systems and also some of the intentional changes to wireless power transmission (WPT) in the history. The basic design for implementation of wireless power system has also been given. Many techniques are there in wireless power transmission like Inductive resonance, Capacitive resonance, Electromagnetic induction, inductive wave coupling, beam forming technique, Near field communication and microwave were discussed.
