  • Abstract:

This paper presents the concept of power transmission from one point to another without using interconnecting wires. This is achieved through the use of electromagnetic induction and resonant magnetic coupling mechanisms which serve the dual purpose of reducing transmission and distribution losses exacerbated by metallic cabling. In this work, a prototype circuit that uses a 12V battery as its source to drive low power devices through wireless medium over 0.3m radius was built. This nearfield transmission is optimized by transmitting and receiving the electromagnetic waves at a regulated kilohertz of resonance frequency. Ways of improving the efficiency of this wireless electric power transmission, with a view to enhancing the technology so as to replace the conventional use of electric cables was also presented. Keywords: power transmission, interconnecting wire, electromagnetic induction, resonant magnetic coupling mechanism, metallic cabling, near-field transmission.
