Abstract :
A novel parallel double-layer spiral coil for coupled magnetic resonance wireless power transfer (WPT) is proposed in this paper. The various characteristics are investigated by using simulation and experiment. Compare to a conventional double-layer spiral coil of the same geometric size, the parallel double-layer spiral coil could improve the quality factor by about 59%, due to the lower resistance. Moreover, the power transfer efficiency characteristics are also analyzed according to the transfer distance. Experimental results demonstrate that the transfer efficiency by using parallel double-layer spiral coil could be greatly improved; these results are in good agreement with the simulation results.
