摘要
高效便捷地获取能量是空间无人作业车的必备功能。基于特殊的宇航空间环境,无线充电方式是空间无人作业车补充能量的重要方式。针对空间无人无线充电系统,介绍了当前空间无人作业车无线充电系统的研究现状,建立了LCC/S补偿拓扑以及后置Buck-Boost电路的硬件拓扑,提出了原边移相以及副边DC闭环的双边控制方法,并研制了一台样机。实验结果表明样机可实现恒压恒流指标为22 V/5 A的无线充电,在传输距离为6.5 cm时,系统的最大偏移距离为9.5 cm,最大传输效率88%。
It is necessary to gain energy efficiently and conveniently for space operation vehicle.Based on the special environmental conditions,wireless charging is an important way to replenish energy for space operation vehicle.For the wireless charging system of space operation vehicle,the research status of space operation vehicle wireless charging system was introduced,the topology including LCC/S and Buck-Boost was developed,the bilateral control strategy including the phase shift control on primary side and DC closed loop control on secondary side was proposed,and a prototype was established.The experiment results show that the prototype achieves wireless charging with 22 V/5 A constant voltage/current output,and the maximum tolerable misaligned distance under 6.5 cm transmitting distance is 9.5 cm with 88%transmitting efficiency.
