逆变器、车载逆变、UPS  

      UPS，又(you)称不(bu)间断电(dian)(dian)(dian)源，是(shi)一(yi)种包含(han)储能(neng)(neng)装(zhuang)置的(de)设备，以逆(ni)变(bian)器(qi)作为(wei)主要组成部(bu)分提供恒(heng)压(ya)恒(heng)频的(de)不(bu)间断电(dian)(dian)(dian)源。主要应(ying)用(yong)于对(dui)供电(dian)(dian)(dian)有严(yan)格要求(qiu)的(de)场(chang)合，为(wei)设备提供不(bu)间断的(de)电(dian)(dian)(dian)力供应(ying)。当市(shi)(shi)电(dian)(dian)(dian)供应(ying)正(zheng)常，UPS将市(shi)(shi)电(dian)(dian)(dian)稳压(ya)后给负载(zai)供电(dian)(dian)(dian)，此(ci)时UPS就是(shi)一(yi)台交(jiao)流(liu)(liu)市(shi)(shi)电(dian)(dian)(dian)稳压(ya)器(qi)，同时向机内(nei)(nei)电(dian)(dian)(dian)池(chi)充电(dian)(dian)(dian)；当市(shi)(shi)电(dian)(dian)(dian)中断或(huo)因意外(wai)状况停电(dian)(dian)(dian)时，UPS立即(ji)开启运(yun)行(xing)，通过内(nei)(nei)部(bu)逆(ni)变(bian)模块，将电(dian)(dian)(dian)池(chi)内(nei)(nei)的(de)电(dian)(dian)(dian)能(neng)(neng)逆(ni)变(bian)转(zhuan)化为(wei)可(ke)供设备继(ji)续运(yun)行(xing)的(de)220V或(huo)者380V交(jiao)流(liu)(liu)电(dian)(dian)(dian)，保证(zheng)设备正(zheng)常运(yun)行(xing)，同时也保护了负载(zai)不(bu)会因意外(wai)停电(dian)(dian)(dian)而损(sun)坏内(nei)(nei)部(bu)硬件。

      逆变器(qi)是把直(zhi)流(liu)电能(电池、蓄(xu)电瓶)转(zhuan)(zhuan)变成(cheng)交流(liu)电(一(yi)般(ban)为220v50HZ正弦(xian)或方(fang)波)。通俗的讲，逆变器(qi)是一(yi)种将直(zhi)流(liu)电(DC)转(zhuan)(zhuan)化为交流(liu)电(AC)的装置(zhi)。它由逆变桥、控制逻辑和(he)滤波电路组成(cheng)。
