描述

雙機(jī)主從式熱備份。將作為從機(jī)的UPSl輸出接到另一臺(tái)作為主機(jī)的UPS2的旁路輸入，正常運(yùn)行時(shí)由UPS2供電，UPSl處于備份。當(dāng)UPS2故障時(shí)，負(fù)載切換至UPS2旁路，由UPSl承擔(dān)負(fù)載供給任務(wù)。此系統(tǒng)結(jié)構(gòu)及控制簡(jiǎn)單，但存在以下缺點(diǎn)：主機(jī)長(zhǎng)時(shí)間工作，而從機(jī)處于長(zhǎng)期待機(jī)狀態(tài)，兩機(jī)的元件老化程度不均勻；在從機(jī)供電的狀態(tài)下，主機(jī)靜態(tài)旁路故障時(shí)將導(dǎo)致系統(tǒng)供電失??；系統(tǒng)負(fù)載不能超過單機(jī)容量且以后無法擴(kuò)容。
