什么是石英燈電子變壓器

石英燈電子變壓器主要(yao)是(shi)在高頻(pin)電(dian)(dian)(dian)(dian)子鎮流(liu)(liu)(liu)器(qi)(qi)電(dian)(dian)(dian)(dian)路(lu)的(de)(de)基礎(chu)上研(yan)制出來的(de)(de)一種(zhong)燈用(yong)變壓(ya)器(qi)(qi)電(dian)(dian)(dian)(dian)路(lu)。電(dian)(dian)(dian)(dian)子變壓(ya)器(qi)(qi)就是(shi)開關穩壓(ya)電(dian)(dian)(dian)(dian)源(yuan)。實際上就是(shi)一種(zhong)逆變器(qi)(qi)。主要(yao)由保護電(dian)(dian)(dian)(dian)路(lu)、橋式整流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)路(lu)、振蕩電(dian)(dian)(dian)(dian)路(lu)、隔離輸(shu)出電(dian)(dian)(dian)(dian)路(lu)組成(cheng)。它(ta)首(shou)先把交流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)變為(wei)直(zhi)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian).然后(hou)(hou)用(yong)電(dian)(dian)(dian)(dian)子元件組成(cheng)一個振蕩器(qi)(qi)直(zhi)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)變為(wei)高頻(pin)交流(liu)(liu)(liu)電(dian)(dian)(dian)(dian).通(tong)過開關變壓(ya)器(qi)(qi)輸(shu)出所(suo)需要(yao)的(de)(de)電(dian)(dian)(dian)(dian)壓(ya)然后(hou)(hou)二次整流(liu)(liu)(liu)供用(yong)電(dian)(dian)(dian)(dian)器(qi)(qi)使(shi)用(yong)。
