Abstract: This paper presents a practical approach for wireless power transfer by inductive coupling. As the protection of environment from pollution green cars (electric cars) are emerging out now a day increasing the requirement of electricity but lacks in electricity power sockets. So to solve this problem a new technology of wireless electricity can be used to charge these electric cars which are more reliable. Under this research, working principle is presented about the design and implementation of wireless power transfer. The experiment results also show the validity of the theoretical analysis. During this research investigation for the need of wireless power transfer and comparison with different materials of coil used was done to demonstrate the power transfer. The advantages, disadvantages, biological impacts and applications of WPT are also presented.
