style="text-indent:25px">UPS，即不間斷電源，是一種含有儲(chǔ)能裝置，以逆變器為主要組成部分的恒壓恒頻的不間斷電源。主要用于給單臺(tái)計(jì)算機(jī)、計(jì)算機(jī)網(wǎng)絡(luò)系統(tǒng)或其它電力電子設(shè)備提供不間斷的電力供應(yīng)。當(dāng)市電輸入正常時(shí)，UPS將市電穩(wěn)壓后供應(yīng)給負(fù)載使用，此時(shí)的UPS就是一臺(tái)交流市電穩(wěn)壓器，同時(shí)它還向機(jī)內(nèi)電池充電；當(dāng)市電中斷(事故停電)時(shí),UPS立即將機(jī)內(nèi)電池的電能，通過(guò)逆變轉(zhuǎn)換的方法向負(fù)載繼續(xù)供應(yīng)220V交流電，使負(fù)載維持正常工作并保護(hù)負(fù)載軟、硬件不受損壞。 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(gòu)時(shí)的考慮重點(diǎn)。市電電壓輸入范圍寬，則表明對(duì)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(duì)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(shuō)明當(dāng)UPS突然由零負(fù)載加到滿(mǎn)負(fù)載時(shí)，輸出電壓的穩(wěn)定性。</p><p style="text-indent:25px">UPS的中文意思為“不間斷電源”，是英語(yǔ)“Uninterruptible Power Supply”的縮寫(xiě)，它可以保障計(jì)算機(jī)系統(tǒng)在停電之后繼續(xù)工作一段時(shí)間以使用戶(hù)能夠緊急存盤(pán)，使您不致因停電而影響工作或丟失數(shù)據(jù)。它在計(jì)算機(jī)系統(tǒng)和網(wǎng)絡(luò)應(yīng)用中，主要起到兩個(gè)作用：一是應(yīng)急使用，防止突然斷電而影響正常工作，給計(jì)算機(jī)造成損害；二是消除市電上的電涌、瞬間高電壓、瞬間低電壓、電線噪聲和頻率偏移等“電源污染”，改善電源質(zhì)量，為計(jì)算機(jī)系統(tǒng)提供高質(zhì)量的電源。從基本應(yīng)用原理上講，UPS是一種含有儲(chǔ)能裝置，以逆變器為主要元件，穩(wěn)壓穩(wěn)頻輸出的電源保護(hù)設(shè)備。主要由整流器、蓄電池、逆變器和靜態(tài)開(kāi)關(guān)等幾部分組成。整流器：整流器是一個(gè)整流裝置，簡(jiǎn)單的說(shuō)就是將交流（AC）轉(zhuǎn)化為直流（DC）的裝置。它有兩個(gè)主要功能：一，將交流電（AC）變成直流電(DC)，經(jīng)濾波后供給負(fù)載，或者供給逆變器；第二，給蓄電池提供充電電壓。因此，它同時(shí)又起到一個(gè)充電器的作用；UPS不間斷電源使負(fù)載維持正常工作并保護(hù)負(fù)載軟、硬件不受損壞。</p><div
