什么是石英燈電子變壓器

石英燈電子變壓器主要(yao)(yao)是(shi)在高(gao)頻電(dian)(dian)(dian)(dian)(dian)子(zi)鎮流(liu)器(qi)(qi)電(dian)(dian)(dian)(dian)(dian)路(lu)的基(ji)礎(chu)上(shang)研制出(chu)來的一種燈用(yong)變(bian)(bian)(bian)壓(ya)器(qi)(qi)電(dian)(dian)(dian)(dian)(dian)路(lu)。電(dian)(dian)(dian)(dian)(dian)子(zi)變(bian)(bian)(bian)壓(ya)器(qi)(qi)就(jiu)是(shi)開關穩壓(ya)電(dian)(dian)(dian)(dian)(dian)源。實際上(shang)就(jiu)是(shi)一種逆變(bian)(bian)(bian)器(qi)(qi)。主要(yao)(yao)由(you)保護(hu)電(dian)(dian)(dian)(dian)(dian)路(lu)、橋式整(zheng)流(liu)電(dian)(dian)(dian)(dian)(dian)路(lu)、振(zhen)蕩電(dian)(dian)(dian)(dian)(dian)路(lu)、隔離輸出(chu)電(dian)(dian)(dian)(dian)(dian)路(lu)組成(cheng)(cheng)。它首先把交流(liu)電(dian)(dian)(dian)(dian)(dian)變(bian)(bian)(bian)為(wei)直流(liu)電(dian)(dian)(dian)(dian)(dian).然后用(yong)電(dian)(dian)(dian)(dian)(dian)子(zi)元(yuan)件(jian)組成(cheng)(cheng)一個振(zhen)蕩器(qi)(qi)直流(liu)電(dian)(dian)(dian)(dian)(dian)變(bian)(bian)(bian)為(wei)高(gao)頻交流(liu)電(dian)(dian)(dian)(dian)(dian).通過(guo)開關變(bian)(bian)(bian)壓(ya)器(qi)(qi)輸出(chu)所需(xu)要(yao)(yao)的電(dian)(dian)(dian)(dian)(dian)壓(ya)然后二次整(zheng)流(liu)供用(yong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)使(shi)用(yong)。

石英燈電子變壓器原理
