什么是石英燈電子變壓器

石英燈電子變壓器主(zhu)要是(shi)在高(gao)頻電(dian)(dian)(dian)子鎮流(liu)器(qi)(qi)電(dian)(dian)(dian)路的(de)基(ji)礎上(shang)研制(zhi)出來的(de)一種燈(deng)用(yong)(yong)變(bian)(bian)壓(ya)器(qi)(qi)電(dian)(dian)(dian)路。電(dian)(dian)(dian)子變(bian)(bian)壓(ya)器(qi)(qi)就是(shi)開關穩壓(ya)電(dian)(dian)(dian)源。實際(ji)上(shang)就是(shi)一種逆(ni)變(bian)(bian)器(qi)(qi)。主(zhu)要由保護電(dian)(dian)(dian)路、橋式整(zheng)流(liu)電(dian)(dian)(dian)路、振蕩電(dian)(dian)(dian)路、隔離輸出電(dian)(dian)(dian)路組(zu)成。它首先把交流(liu)電(dian)(dian)(dian)變(bian)(bian)為直(zhi)流(liu)電(dian)(dian)(dian).然后(hou)用(yong)(yong)電(dian)(dian)(dian)子元件組(zu)成一個振蕩器(qi)(qi)直(zhi)流(liu)電(dian)(dian)(dian)變(bian)(bian)為高(gao)頻交流(liu)電(dian)(dian)(dian).通過開關變(bian)(bian)壓(ya)器(qi)(qi)輸出所(suo)需要的(de)電(dian)(dian)(dian)壓(ya)然后(hou)二次(ci)整(zheng)流(liu)供用(yong)(yong)電(dian)(dian)(dian)器(qi)(qi)使用(yong)(yong)。
