什么是石英燈電子變壓器

石英燈電子變壓器主要(yao)是在高(gao)頻(pin)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子鎮流(liu)器(qi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)的(de)基礎上研(yan)制出(chu)來的(de)一種(zhong)燈用(yong)變(bian)(bian)壓(ya)器(qi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子變(bian)(bian)壓(ya)器(qi)就是開(kai)關穩壓(ya)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源。實際上就是一種(zhong)逆(ni)變(bian)(bian)器(qi)。主要(yao)由保護電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)、橋式(shi)整(zheng)流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)、振(zhen)蕩電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)、隔離輸(shu)出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)組(zu)成。它首先把交(jiao)流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)變(bian)(bian)為直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian).然后用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子元件組(zu)成一個振(zhen)蕩器(qi)直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)變(bian)(bian)為高(gao)頻(pin)交(jiao)流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian).通過開(kai)關變(bian)(bian)壓(ya)器(qi)輸(shu)出(chu)所需(xu)要(yao)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)然后二(er)次(ci)整(zheng)流(liu)供用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)使用(yong)。
