什么是石英燈電子變壓器

石英燈電子變壓器主要(yao)(yao)是在高(gao)頻(pin)(pin)電(dian)(dian)(dian)子鎮流(liu)器(qi)電(dian)(dian)(dian)路的(de)基礎(chu)上研制出(chu)來的(de)一(yi)種燈(deng)用變(bian)壓(ya)器(qi)電(dian)(dian)(dian)路。電(dian)(dian)(dian)子變(bian)壓(ya)器(qi)就是開(kai)關穩壓(ya)電(dian)(dian)(dian)源。實際上就是一(yi)種逆變(bian)器(qi)。主要(yao)(yao)由保護電(dian)(dian)(dian)路、橋式整流(liu)電(dian)(dian)(dian)路、振(zhen)蕩電(dian)(dian)(dian)路、隔離輸(shu)出(chu)電(dian)(dian)(dian)路組成(cheng)。它首先把交流(liu)電(dian)(dian)(dian)變(bian)為直流(liu)電(dian)(dian)(dian).然后(hou)用電(dian)(dian)(dian)子元件組成(cheng)一(yi)個振(zhen)蕩器(qi)直流(liu)電(dian)(dian)(dian)變(bian)為高(gao)頻(pin)(pin)交流(liu)電(dian)(dian)(dian).通過開(kai)關變(bian)壓(ya)器(qi)輸(shu)出(chu)所需(xu)要(yao)(yao)的(de)電(dian)(dian)(dian)壓(ya)然后(hou)二(er)次整流(liu)供用電(dian)(dian)(dian)器(qi)使(shi)用。
