ups電源是由很多主要部件組成的一個備用電源系統，用以滿足重要核心設備的應急用電需求，在ups電源主要組成部件中，逆變器技術是要有一定要求的，下面就簡單介紹一下ups電源電池逆變器技術要求吧。

ups電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)逆(ni)變器的(de)(de)輸(shu)入來自經過(guo)(guo)整(zheng)(zheng)流(liu)器整(zheng)(zheng)流(liu)后的(de)(de)直(zhi)流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)和所用直(zhi)流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)，也就是(shi)ups電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池所儲存的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)能。旁路交流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)正(zheng)常時(shi)，逆(ni)變器輸(shu)出頻率(lv)保持(chi)與旁路交流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)同(tong)步，若旁路交流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)的(de)(de)頻率(lv)和電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓偏差(cha)超(chao)過(guo)(guo)逆(ni)變器容差(cha)允許(xu)值時(shi)，同(tong)步回路應自動(dong)關斷，逆(ni)變器則按其(qi)內部(bu)基(ji)準(zhun)頻率(lv)運行(xing)，直(zhi)至旁路交流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)恢(hui)復至逆(ni)變器容差(cha)允許(xu)范圍內時(shi)再(zai)與其(qi)保持(chi)同(tong)步。在外部(bu)同(tong)步電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)偏離或恢(hui)復至容差(cha)范圍，IPS應不(bu)誤切(qie)換供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)且輸(shu)出頻率(lv)及相位不(bu)應有(you)暫態過(guo)(guo)程(cheng)，頻率(lv)變化(hua)也應限制(zhi)于2Hz/s范圍內；

在滿(man)負(fu)(fu)荷(he)情(qing)況(kuang)下(xia)進行負(fu)(fu)載(zai)投(tou)切時或因逆變器故(gu)障而切換(huan)交(jiao)流(liu)電源時，UPS的瞬態輸(shu)(shu)出(chu)電壓變化范(fan)圍不(bu)應超過(guo)5%額定輸(shu)(shu)出(chu)電壓，且在3周內能(neng)夠恢復(fu)，此外，UPS電源還應具有(you)自動(dong)穩壓功能(neng)，在輸(shu)(shu)入電壓波動(dong)或負(fu)(fu)載(zai)變化時，能(neng)夠自動(dong)調節輸(shu)(shu)出(chu)電壓的穩定。

額(e)(e)定(ding)功率因(yin)數(shu)下，負載(zai)在0~100%范圍內按(an)20%增(zeng)/減(jian)時(shi)，UPS穩杰輸出(chu)電(dian)壓變(bian)化不應(ying)超過1%額(e)(e)定(ding)輸出(chu)電(dian)壓。逆(ni)變(bian)器在功率因(yin)數(shu)0.7~0.9運行時(shi)，最(zui)大(da)沖(chong)擊負荷(he)為額(e)(e)定(ding)值(zhi)的(de)1.5倍時(shi)，應(ying)能承受(shou)60s;逆(ni)變(bian)器應(ying)具有過流保護(hu)特性。UPS的(de)過電(dian)流保護(hu)應(ying)能保證在負荷(he)發生短路或(huo)電(dian)流超過允許(xu)的(de)極限值(zhi)時(shi)及時(shi)動作，使其免受(shou)浪涌電(dian)流的(de)損傷。
