摘　　要：针对单台稳压电源功率无法满足大型航天器测试供电的问题,设计了一种多电源并联均流的航天器测试供电系统。采用通用性强的VC#软件编程实现了均流的自动闭环控制,通过硬件架构设计使得系统中各电源电气独立、互为冗余。实验结果表明,该系统均流效果显著、负载动态响应快、可靠性高,在大功率稳压供电中具有较高的工程应用价值。To solve the problem of a single power supply can not meet the large-scale power supply in spacecraft test, a new type of multi power supply system with parallel current sharing is designed. VC# software programming was adopted to realize the automatic closed-loop current sharing. The hardware architecture design makes the power of the system independent and redundant. Experimental results show that the system has the advantages of favorable current sharing effect, fast transient response and high reliability, and has high engineering application value in super power supply.
