Wireless Power Transmission through Air, Wood & Concrete Medium at Utility Frequency of 50 Hz

Abstract

An attempt is made to perform wireless power transmission using circuits resonating at the utility frequency of 50 Hz. The purpose of this project is to develop a method for transmitting electrical power through air, wood and concrete walls. An equation for the theoretical transmission efficiency that considers the copper and core losses was derived through equivalent circuit analysis. The transmission efficiency was found to be strongly dependent on the shape of the magnet pole pieces. The ultimate goal of this project is to do simulation using matlab and hardware design is done and obtained values are compared with theoretical and simulated values. There are three possible methods of wireless power transmission (WPT) electromagnetic induction, magnetic resonance, and radio waves.In the present study, the efficiency of resonant power transmission through concrete was investigated at the utility frequency of 50 Hz, using magnet pole piece configurations
