如(ru)今，隨著通(tong)(tong)信技術的(de)(de)(de)(de)(de)飛速發展，數據中(zhong)心(xin)規模越來(lai)越大，各種通(tong)(tong)信設(she)備對不(bu)間(jian)斷電(dian)(dian)(dian)源(yuan)(yuan)——UPS的(de)(de)(de)(de)(de)供電(dian)(dian)(dian)質(zhi)(zhi)(zhi)量(liang)提出了(le)更高(gao)的(de)(de)(de)(de)(de)要求。但是UPS設(she)備本(ben)設(she)施很嚴重的(de)(de)(de)(de)(de)諧波(bo)(bo)(bo)源(yuan)(yuan)，它產(chan)生的(de)(de)(de)(de)(de)諧波(bo)(bo)(bo)一般為(wei)5次(ci)、7次(ci)和11次(ci)諧波(bo)(bo)(bo)，可造成(cheng)配電(dian)(dian)(dian)線(xian)纜、變壓器(qi)發熱，降低通(tong)(tong)話質(zhi)(zhi)(zhi)量(liang)，空氣(qi)開關誤動作(zuo)等不(bu)良(liang)后(hou)果，甚(shen)至會使(shi)通(tong)(tong)信中(zhong)斷等。UPS在(zai)整流充電(dian)(dian)(dian)過(guo)程中(zhong)所(suo)產(chan)生的(de)(de)(de)(de)(de)諧波(bo)(bo)(bo)一方(fang)面(mian)會影(ying)響到計算機網(wang)絡中(zhong)來(lai)，造成(cheng)網(wang)絡莫名其(qi)妙的(de)(de)(de)(de)(de)停機錯誤。另一方(fang)面(mian)，這(zhe)些諧波(bo)(bo)(bo)反(fan)過(guo)來(lai)又使(shi)UPS中(zhong)的(de)(de)(de)(de)(de)蓄電(dian)(dian)(dian)池的(de)(de)(de)(de)(de)極(ji)板加(jia)速氧化，縮(suo)短蓄電(dian)(dian)(dian)池的(de)(de)(de)(de)(de)使(shi)用(yong)壽命，從(cong)而為(wei)生產(chan)和管理帶(dai)來(lai)很大的(de)(de)(de)(de)(de)損(sun)失。因此需要對UPS產(chan)生的(de)(de)(de)(de)(de)諧波(bo)(bo)(bo)進行治理，提高(gao)UPS功率因數，改善電(dian)(dian)(dian)能質(zhi)(zhi)(zhi)量(liang)……
