基于双耦合线圈的无人机轻量化无线充电耦合机构设计
Design of Lightweight Wireless Charging Coupling Mechanism for UAVs Based on Dual Coupling Coils
摘要
Abstract
A UAV wireless charging coupling mechanism based on dual coupling coils is designed to meet the wireless charging requirements of medium and large UAVs,which has a high transmission energy efficiency and certain offset resistance while satisfying the lightweight design on the UAV side.The dual receiver coils are mounted at the bot-tom bracket positions on both sides of the UAV,and the dual transmitter coils are mounted on a trapezoidal transmitter platform with the same tilt angle as the UAV bracket to reduce the large range of UAV deflections.Meanwhile,a cas-cading series connection is used to ensure the uniformity of wireless charging.A series-series(S-S)compensation structure is also used.The finite element simulation is applied to compare and analyze the influence of different parameters of coupling coils on the transmission efficiency,and the design of coupling coils is optimized based on the principle of light weight.A UAV wireless charging experimental system was built,and results show the proposed coupling mechanism can effectively charge the UAV battery at 1.2 kW power with a transmission efficiency of 95.554%.The mass of the UAV-side coupling mechanism was 320 g,which meets the requirements of lightweight design of UAV coupling mechanism and also has certain offset resistance.关键词
