Abstract

In this paper, we present the concept of Transmitting Power without wires. The Wireless power transmission is implemented by the concept called Magnetic Resonant Coupling. We present new analysis that yields critical insight into design of practical systems.A circuit model is presented which works on Adaptive frequency tuning technique which compensates for efficiency variations encountered when the transmitter to receiver distance and/or orientation are varied. The method demonstrated in this paper allows a fixed-load receiver to be moved to nearly any position and/or orientation within the range of the transmitter and still achieve a near constant efficiency of over 70% for a range of 11-52 cm.
