WIRELESS POWER TRANSMISSION SYSTEM

Abstract

Wireless energy transfer or wireless power is the transmission of electrical energy from a power source to an electrical load without interconnecting wires. Wireless transmission is useful in cases where interconnecting wires are inconvenient, hazardous, or impossible. The problem of wireless power transmission differs from that of wireless telecommunications, such as radio. In the latter the proportion of energy received becomes critical only if it is too low for the signal to be distinguished from the background noise. With wireless power, efficiency is the more significant parameter. The most common form of wireless power transmission is carried out using direct induction. This action of an electrical transformer is the simplest form of wireless power transmission. The primary and secondary circuits of a transformer are not directly connected. Energy transfer takes place through a process known as mutual induction. In this project electric power to be transmitted is given to the the induction coil. Thus the flux will be created in the coil which placed in the transmitter part. When the coil in the receiver part comes into contact with the flux created by the transmitter part coil, power will be generated in the coil (mutual induction). Thus the generated power can be utilized by the user. Finally the power will be transmitted in wireless manner.
