Wireless Power Transfer, Magnetic Resonant Coupling, Quality Factor
Abstract
Wireless power transmission (WPT) is the transmission of electrical energy without using any conductor or wire. It is useful to transfer electrical energy to those places where it is hard to transmit energy using conventional wires. This paper investigates the effect of various parameters of the design of magnetically coupled resonant circuits for non-radiative WPT. Such as coil diameter, number of turns, wire diameter, spacing between turns (pitch), load resistance, and frequency and their influence on the efficiency and power delivered to the load. Results are presented in the form of plots for power transfer efficiency of the system to show the comparison of power and efficiency with distance.
