Development of an Efficient Wireless Power Transfer System

Abstract

Accessing of power is a crucial necessity for any electrical/electronic circuit. Power can be transferred by physically i.e wires, cables etc or non-physically i.e wireless. Power transmissionfrom the source to load without any connecting wire or cable is called Wireless Power Transmission. Wireless power transfer is the rising pattern in the world today. The concept of power transfer without conducting wire was realized by Nikola Tesla. By using this concept transferring power can eliminates the use conventional copper cables and current carrying conductor. Different techniques are there for transfer power wirelessly for near field and far field also. This wireless power transmission technique is useful where conducting wires are inconvenient, or impossible. With wireless power transfer the important parameter is the efficiency. In this project presents the concept of transmitting power without using wires i.e. inductive coupling by which the transmission and distribution losses can be reduced. To improve the efficiency of wireless power, different types of receiver circuit also used. We also discussed the different types, block diagram, efficiency of Wireless Power Transmission (WPT).
