為有效(xiao)地把交流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)轉化(hua)成(cheng)直流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)，交流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)經整(zheng)流(liu)(liu)和(he)濾波(bo)后，輸出(chu)一個(ge)用戶需要的(de)(de)直流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)。調整(zheng)開關觸發(fa)角，將單(dan)極性脈沖波(bo)斬波(bo)成(cheng)一個(ge)高(gao)頻(pin)(pin)脈沖波(bo)，然后經過高(gao)頻(pin)(pin)變(bian)壓(ya)(ya)(ya)(ya)(ya)器(qi)，就得到所(suo)要求的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)，此電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)再被整(zheng)流(liu)(liu)和(he)濾波(bo)。控(kong)制電(dian)(dian)(dian)(dian)(dian)(dian)路提取輸出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)信(xin)號，根據參考電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)值決定開關的(de)(de)占空比，能量從主電(dian)(dian)(dian)(dian)(dian)(dian)路傳(chuan)輸到高(gao)頻(pin)(pin)變(bian)壓(ya)(ya)(ya)(ya)(ya)器(qi)的(de)(de)二次側。該方(fang)法，與線性類電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)比較，該電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)能在(zai)可變(bian)負(fu)載(zai)下工(gong)作，不會消耗更(geng)多的(de)(de)發(fa)熱功(gong)率。
