市電有時會發(fā)生電壓上涌和下陷或瞬間壓降，這樣的問題會影響設(shè)備的精細(xì)度，嚴(yán)重時會損壞精密設(shè)備使用戶遭受損失。UPS系統(tǒng)可以提供穩(wěn)定的電壓，從而保護(hù)設(shè)備。 </p> <p> 控制橫模和共模噪聲的作用 </p> <p>

UPS系統(tǒng)是數(shù)據(jù)中心供電連續(xù)性的重要保障，UPS系統(tǒng)的可靠性直接影響數(shù)據(jù)中心的可靠性，同時，在絕大多數(shù)數(shù)據(jù)中心，UPS系統(tǒng)的損耗可占IT設(shè)備能耗的10%以上。因此，提高UPS系統(tǒng)的可靠性，同時降低其損耗，就成為數(shù)據(jù)中心UPS系統(tǒng)架構(gòu)演變的主旋律。 </p><p> UPS作為保護(hù)性的電源設(shè)備，它的性能參數(shù)具有重要意義，應(yīng)是我們選購時的考慮重點(diǎn)。市電電壓輸入范圍寬，則表明對市電的利用能力強(qiáng)（減少電池放電）。輸出電壓、頻率范圍小，則表明對市電調(diào)整能力強(qiáng)，輸出穩(wěn)定。波形畸變率用以衡量輸出電壓波形的穩(wěn)定性,而電壓穩(wěn)定度則說明當(dāng)UPS突然由零負(fù)載加到滿負(fù)載時，輸出電壓的穩(wěn)定性。 </p> <p> 還有UPS效率、功率因數(shù)、轉(zhuǎn)換時間等都是表征UPS性能的重要參數(shù)，決定了對負(fù)載的保護(hù)能力和對市電的利用率。性能越好，保護(hù)能力也越強(qiáng)，總的來說，離線式UPS對負(fù)載的保護(hù)很差，在線互動式略優(yōu)之，在線式則幾乎可以解決所有的常見電力問題。當(dāng)然成本也隨著性能的增強(qiáng)而上升。因此用戶在選購UPS時，應(yīng)根據(jù)負(fù)載對電力的要求程度及負(fù)載的重要性不同,而選取不同類型的UPS。互動式：具有濾波功能，抗市電干擾能力強(qiáng)，轉(zhuǎn)換時間小于4ms，逆變輸出為模擬正弦波，價格遠(yuǎn)低于在線式；</p><div

在線互動式UPS電源在變壓器抽頭切換的過程中，雙向變換器作為逆變器方式工作。蓄電池供電，因此能實(shí)現(xiàn)輸出電壓的不間斷，同樣在由市電供電到電池供電的切換過程中也能做到?jīng)]有轉(zhuǎn)換時間。在線互動式UPS電源的電路實(shí)現(xiàn)簡單，沒有單獨(dú)的充電器，帶來的是生產(chǎn)成本的降低和可靠性的提高。 </p> <p> 這類產(chǎn)品在市電供電工作時也不存在AC／DC、DC／AC的轉(zhuǎn)換，使整機(jī)效率有所提高。在線互動式UPS很好地結(jié)合了后備式UPS和在線式UPS的許多優(yōu)點(diǎn)，是一種很不錯的變換形式。但是由于它使用的是工頻變壓器，同樣有笨重、體積大的問題。

在線互動式UPS電源也被稱為3端口式UPS電源，使用的是工頻變壓器。從能量傳遞的角度來考慮，其變壓器存在3個能量流動的端口：端口1連接市電輸入；端口2通過雙向變換器與蓄電池相連；端口3輸出。 </p> <p> 市電供電時，交流電經(jīng)端口1流入變壓器，在穩(wěn)壓電路的控制下選擇合適的變壓器抽頭接入，同時在端口2的雙向變換器的作用下借助蓄電池的能量轉(zhuǎn)換共同調(diào)節(jié)端口3上的輸出電壓，以此來達(dá)到比較好的穩(wěn)壓效果；市電掉電時，蓄電池通過雙向變換器經(jīng)端口2給變壓器供電，維持端口3上的交流輸出。眉山科士達(dá)ups不間斷電源公司</p><p
