Design of variable direction wireless power transfer system based on metamaterial
Source abstract
Abstract
In complex environments, such as mines, ports, and pipelines, wireless power transfer technology is a convenient and safe power supply method. However, the offset and change in direction of the receiving coil greatly weaken the power transfer performance. To address this issue, this paper proposes a variable direction wireless power transfer device for mining based on metamaterials. According to the relationship between incident angle, refracted angle, and permeability, three different metamaterials are selected to fabricate a metamaterial slab arranged in 3 × 3 using printed circuit board technology. Experimental results show that when the transmitting coil and receiving coil are perpendicular to and deviate from each other, the designed power transfer system with the metamaterial slab can effectively increase power transfer by 117.9%. The proposed variable direction transfer system only needs a metamaterial slab without an additional power supply or control structure, and it is convenient for large-scale manufacturing and application.
