光伏逆(ni)變(bian)(bian)(bian)器(qi)的(de)結構原理逆(ni)變(bian)(bian)(bian)器(qi)是一種由(you)(you)(you)半導(dao)體器(qi)件(jian)組成(cheng)的(de)電(dian)力(li)調整裝置(zhi)，主(zhu)要用(yong)于把直(zhi)流(liu)電(dian)力(li)轉換(huan)成(cheng)交流(liu)電(dian)力(li)。一般由(you)(you)(you)升壓(ya)(ya)(ya)回(hui)路(lu)(lu)和逆(ni)變(bian)(bian)(bian)橋式(shi)回(hui)路(lu)(lu)構成(cheng)。升壓(ya)(ya)(ya)回(hui)路(lu)(lu)把太陽電(dian)池的(de)直(zhi)流(liu)電(dian)壓(ya)(ya)(ya)升壓(ya)(ya)(ya)到逆(ni)變(bian)(bian)(bian)器(qi)輸出(chu)控(kong)制所需的(de)直(zhi)流(liu)電(dian)壓(ya)(ya)(ya)；逆(ni)變(bian)(bian)(bian)橋式(shi)回(hui)路(lu)(lu)則把升壓(ya)(ya)(ya)后的(de)直(zhi)流(liu)電(dian)壓(ya)(ya)(ya)等(deng)價(jia)地(di)轉換(huan)成(cheng)常(chang)用(yong)頻率(lv)的(de)交流(liu)電(dian)壓(ya)(ya)(ya)。逆(ni)變(bian)(bian)(bian)器(qi)主(zhu)要由(you)(you)(you)晶體管等(deng)開關元件(jian)構成(cheng)，通過有規則地(di)讓開關元件(jian)重(zhong)復(fu)開-關（ON-OFF），使直(zhi)流(liu)輸入(ru)變(bian)(bian)(bian)成(cheng)交流(liu)輸出(chu)。當然，這樣單純地(di)由(you)(you)(you)開和關回(hui)路(lu)(lu)產生的(de)逆(ni)變(bian)(bian)(bian)器(qi)輸出(chu)波形并不(bu)實用(yong)。
