摘要
主要对集中型应急电源带不同负载时的切换时间要求和实现方式进行了研究,以期对应急电源的设计与使用提供合理的解决方案。特别分析了毫秒级切换时间的电路实现方式。提出在兼顾经济性和可靠性时,热后备+静态旁路方式是优选的工作方式。
The requirement of switching time and the implementation mode were discussed when centralized emergency power supply was connected with different loads, in order to offer proper solution in designing and using of emergency power supply. The implementation mode of millisecond switching time circuit was specially analyzed, It was pointed out that the hot backup with static by-pass was the best working mode when the economy and reliability were considered at the same time.
