| 摘 要： | 文章列举了航天器二次电源中常用的冗余设计方式,并针对某航天器热备份冗余二次电源在轨出现的“备压主”现象进行了详细分析,说明了其产生的机理,并通过多个产品的地面试验进行了验证和分析,对热备份冗余二次电源的工作模式有了进一步的认知,指出“备压主”是这种冗余设计方式的一种特定工作模式,而非产品故障。

| Abstract: | This paper reviews the backup redundancy control schemes involved in the secondary power supply of spacecraft. The phenomenon named the “backup suppressing main” in the power supply is analyzed, as well as the causes of its generation. The results of numerous experiments on the ground provide an understanding of the operating modes of the heat backup secondary power supply. It is shown that the so-called “backup suppressing main” is a particular operating mode, not the product's failure. |
