選件）、蓄電池開關(guān)等組成。該UPS不是根據(jù)需要從主電源切換到備用電源，而是將所有交流電源轉(zhuǎn)換為直流電。一些直流電源為電池充電，其余部分轉(zhuǎn)換回交流電以為連接的設(shè)備供電。這種雙重轉(zhuǎn)換過程基本上可以防止任何電源事件到達設(shè)備，從而產(chǎn)生比較大的保護級別。優(yōu)點：無論逆變器的供電是由交流電源或是電池，它提供負(fù)載的電源都是連續(xù)的；負(fù)載同上線供電系統(tǒng)相隔離，因此防止了任何上線的干擾送給負(fù)載；很寬的輸入電壓容限范圍和精細的輸出電壓調(diào)整；在交流輸入電源發(fā)生故障時，立即轉(zhuǎn)換到電池放電方式運行；可以不中斷供電地轉(zhuǎn)換到旁路方式；缺點：價格較高；因為**的負(fù)載功率需要經(jīng)過整流和逆變兩次電力變換，損耗較大，降低了系統(tǒng)總效率；由于雙變換UPS輸入端一般都采用相控整流器，相控整流器產(chǎn)生的輸入諧波電流對交流輸入電源造成嚴(yán)重干擾。如果你只是運行一臺機器，比如在小型辦公室或家庭式辦公室環(huán)境中，那么備用UPS可能剛好滿足你的要求。交互式UPS有助于降低UPS的能耗，其高可用性、簡單的設(shè)計和相對較低的成本使該系統(tǒng)成為小型企業(yè)的比較好選擇。但對于大型數(shù)據(jù)中心來說，宕機是不可接受的，其設(shè)備必須受到保護，不能受任何電源質(zhì)量問題的影響。</p><div
