Abstract: In this system allow to be transferred from one electrical network to another electrical network without needs for wires exposed contacts basically there have rapid expansion of WPT in cell (mobile) phone charger and electric CFL (bulb) and dynamic charging and electric vehicles also street light, road powered electric be in high stipulation for electric power to be supplied in the upcoming time. vehicles and we used magnetic induction using copper wire with diameter this wireless power transfer filed would Wireless power transfer is a new technology to transfer electrical power without any physical contact between the source and the load. The aim of this paper is to propose the use of a simple, cheap and easy technique for mid-range wireless power transfer. The various technologies available so far for wireless transmission of electricity and the need for a wireless system of energy transmission are discussed here. The core of the used technology is making use of the magnetic resonance concept for transmitting the power wirelessly. A wireless power transfer system for implanted medical devices which uses antenna area 100 times smaller than previous designs is presented.

Keywords: Wireless power, energy coupling, Transmission, coils, electrical load.
