Abstract
This paper analyzes the effects of coaxial cables in the magnetic resonant wireless power transfer (WPT) system. The experimental results show that the transfer efficiency of WPT system would change when different coaxial cables were connected to the source and load coils. Some special phenomena are revealed and a possible interpretation is proposed in this paper. Experiment results show that the proposed system can dramatically improve the efficiency and extend the power transfer distance. In the same size of MIT's helix, the efficiency of the WPT system increased to near 50% at the distance of 4.8 meters, while near 50% of 2 meters by MIT in 2007. In addition, we succeed to light a low voltage bulb at the distance of 4.8 meters.
