Abstract
A great concern has been voiced in recent years over the extensive use of energy, the limited supply of resourses, and the pollution of the environment from the use of present energy conversion systems. Electrical power accounts for much of the energy consumed. One of the major issue in power system is the losses occurs during the transmission and distribution of electrical power. As the demand increases day by day, the power generation increases and the power loss is also increased. The major amount of power loss occurs during transmission and distribution. The resistance of the wire used in the electrical grid distribution system causes a loss of 26-30% of the energy generated. This loss implies that our present system of electrical distribution is only 70-74% efficient. The above discussed problem can be solved by choose an alternative option for power transmission which could provide much higher efficiency, low transmission cost and avoid power theft. Wireless power transmission is one of the promising technologies and may be the righteous alternative for efficient power transmission. This paper focuses on the past and future possible advancements in WPT. Also the proposed method and technologies in WPT that will make the loss of energy during transmission and distribution to minimum are discussed
