是(shi)主要用于小型電(dian)(dian)(dian)子設(she)備及電(dian)(dian)(dian)子電(dian)(dian)(dian)器的供電(dian)(dian)(dian)電(dian)(dian)(dian)源變(bian)換設(she)備，一般(ban)由外殼、電(dian)(dian)(dian)源變(bian)壓器和整(zheng)流(liu)電(dian)(dian)(dian)路組(zu)成(cheng)。根(gen)據連(lian)接方式(shi)可分(fen)為桌面式(shi)及插墻(qiang)式(shi)。根(gen)據輸出(chu)電(dian)(dian)(dian)流(liu)類型可分(fen)為交(jiao)流(liu)輸出(chu)型和直流(liu)輸出(chu)型。目前廣泛配套于筆記本計(ji)算機(ji)、手提電(dian)(dian)(dian)話、家用IT設(she)備等設(she)備中。

現(xian)實中我(wo)們(men)接觸到(dao)的電(dian)(dian)(dian)(dian)源(yuan)適配器(qi)多是開(kai)關(guan)電(dian)(dian)(dian)(dian)源(yuan)。開(kai)關(guan)電(dian)(dian)(dian)(dian)源(yuan)是指(zhi)通過現(xian)代電(dian)(dian)(dian)(dian)子技術，控制開(kai)關(guan)管開(kai)通和關(guan)斷的時(shi)間比率，維(wei)持穩定(ding)輸出電(dian)(dian)(dian)(dian)壓(ya)的一(yi)種電(dian)(dian)(dian)(dian)源(yuan)，電(dian)(dian)(dian)(dian)源(yuan)適配器(qi)的開(kai)關(guan)電(dian)(dian)(dian)(dian)源(yuan)一(yi)般由(you)脈沖寬(kuan)(kuan)度調制(PWM)控制IC和MOSFET構成，好處(chu)：轉(zhuan)換效率高(gao)，體積小，可以在(zai)寬(kuan)(kuan)電(dian)(dian)(dian)(dian)壓(ya)范圍內工作。不足：發生(sheng)故障(zhang)時(shi)檢修難度較(jiao)大(da)，對電(dian)(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)(dian)路(lu)干擾較(jiao)大(da)。

  正(zheng)規電(dian)源適配器上都有(you)標(biao)示(shi)著(zhu)功(gong)率(lv)，輸(shu)入輸(shu)出(chu)電(dian)壓和(he)電(dian)流(liu)量等指標(biao)的(de)一個銘牌。值得注意的(de)是輸(shu)入電(dian)壓范圍(wei)。一般來說，輸(shu)入電(dian)壓為110V-240V的(de)電(dian)源適配器則(ze)可以全球(qiu)通用，適合所有(you)國家及地區。
