光(guang)伏發(fa)電(dian)(dian)(dian)逆變隔離變壓器(qi)是利用半(ban)導(dao)體界面的(de)光生伏特(te)效應(ying)而(er)將光能(neng)直接轉變為電(dian)(dian)(dian)能(neng)的(de)一種技術(shu)。這種技術(shu)的(de)關鍵元件是太(tai)陽能(neng)電(dian)(dian)(dian)池(chi)。太(tai)陽能(neng)電(dian)(dian)(dian)池(chi)經過串聯后進行封裝保護可形成(cheng)大面積的(de)太(tai)陽電(dian)(dian)(dian)池(chi)組件，再配合上功率控(kong)制(zhi)器(qi)等部件就形成(cheng)了光伏發(fa)電(dian)(dian)(dian)裝置。
光伏(fu)變(bian)壓器(qi)一般用來于太陽能(neng)逆變(bian)。因為(wei)光伏(fu)變(bian)壓器(qi)本身光電(dian)效(xiao)率低，所以特(te)別要(yao)求變(bian)壓器(qi)的效(xiao)率高。
光伏(fu)并網逆變(bian)隔離(li)變(bian)壓器網側接線dyn11,Y/YNO，光伏(fu)隔離(li)變(bian)壓器可(ke)添(tian)加時間繼電器設置(zhi)白天(tian)工(gong)作，晚上停止(zhi)，降(jiang)低(di)空載損耗電能。
