Optimizing the design parameters of a wireless power transfer system for maximizing power transfer efficiency: A simulation study

In respect to the main goal of our ongoing work for maximizing the efficiency of wireless power transfer (WPT) systems, we focus in this paper on the results obtained from experiments conducted on a simulated WPT system after varying several design parameters. The selected parameters are classified into electrical design parameters related to the electrical circuit of the WPT system and the geometrical design parameters related directly to the coils used to transmit/receive the electric power. The model is simulated using Ansys/Maxwell 3-D software package. The results of this study have shown that the efficiency can be significantly improved by optimizing some simple, yet relevant, geometrical design parameters such as the size of the coils and/or by installing repeater coils between the transmitter and receiver.
