Abstract:

Because of its high efficiency and convenience,unmanned aerial vehicle (UAV) patrol inspection has become an important trend in the field of electric power patrol.The short range of UAV patrol inspection seriously restricts the work radius of UAV.The charging autonomy and intellectualization of UAV can be greatly improved by wireless power transfer (WPT).Firstly,the anti-offset performance of coil structures with different shapes is studied comparatively.And the range of mutual inductance of the coupling structure is obtained by analyzing the voltage and current constraints of system.Secondly,the coupling structure is optimized with the aim of lightweight pickup based on the parametric scanning function of COMSOL finite element simulation software.Finally,a WPT system based on the optimized coupling structure is built with efficiency of 91%,which is in good agreement with the theoretical analysis.

Key words: ummanned aerial vehicle UAV, coupling mechanism, anti-offset, parametric scanning, wireless power transfer(WPT)
