Abstract
In this paper, an adjustable coupling method is proposed to improve the transfer efficiency of magnetically coupled resonant wireless power transfer system (MCR-WPT) under various transfer distances. By changing the offset distance between the driving loop and the transmitter coil, the coupling coefficient was adjusted to make the MCR-WPT have a better transfer efficiency at various transfer distances. The efficiency of simulation is 41.1% higher than the original MCR-WPT and the experimental results are basically consistent with the simulation.
