A Comprehensive Review On Wireless Power Transmission

The percentage of energy sent that reaches its destination is the efficiency of an energy transferring system. Energy transfer via wires is considerably more reliable and efficient way since wires are a low-loss medium of confining and guiding energy to where it is utilized. Wireless energy transfer still works very well in general at short distances, and make sure to become more efficient over a long-distance transfer is possible if the size of transmitters / receivers are physically large, or if the energy can be synthesized in the form of a tight beam. The energy transferring system efficiency is calculated in the term of percentage energy sent that arrives at its destination. Because wires are a low-loss medium of confining and guiding energy, also sending it through wires is often more efficient. Mostly, in the distribution system, the wire resistivity of the electrical grid results in a loss of 26-30% of generated energy. Because of that loss implies to our current electrical distribution system is only 70-74% efficient. There are many hilly and even rural areas the world those facing shortage of energy in domestic as well as in commercial or industrial utilization in such evolutionary era. However, there is no way to deliver power up to their daily base needs. Even the people of South Asia and Africa requires electricity to power pumps that will require the electrical power to facalitate them with the equal opportunity to meet their needs in standing along with Western nations. When conventional wires are unaffordable, inconvenient, costly, dangerous, unwanted, or impossible, wireless power transmission (WPT) can be employed in the place where energy delivery needs to be continuous or instantaneous. Microwaves, millimeter waves, and lasers can all be used to transmit power wirelessly. WPT otherwise be impossible to fullfil the requirements of trasmission of power. The goal of this research work is to elebarate and meets the challenges that arise during transmission of power wirelessly on the basis of comparative analysis of different techniques and to propose a suitable model for overcoming these challenges. It is a technology that can transport power to places that would be impossible to reach by conventional techiques and gives appropriate solution of different concerned parameters.
