摘要
介绍了我国第一颗微小卫星创新一号(CX-1)电源分系统的性能、组成、工作原理,以及太阳电池阵、镉镍电池组和电源控制器等的设计和相应参数。分析了设计中采用的三域控制统一母线调节、高效三结砷化镓太阳电池发电和充电V-T曲线智能化控制管理等关键技术。飞行试验结果表明,CX-1卫星电源分系统的性能优良、工作可靠,达到了设计要求。
The performance, construction, principle, and design and parameters of solar array, Cd-Ni battery and power controller of the power subsystem for CX-1 satellite, which was the firstmicro-satellite in China, were introduced in this paper. The key technologies such as 3-region control and uniform bus alignment, high efficiency power generating of 3-node GaAs solar cell, and intelligent control management of charge V-T curve were also analyzed. The on-orbit data showed that the function of the power subsystem operated with high performance and reliability which met the reauirements in design.
