什么是電源適配器?使用電源(yuan)適配器(qi)相對(dui)有哪些(xie)(xie)作用呢?在什么情況(kuang)下(xia)用外置的電源(yuan)適配器(qi)比較好呢?下(xia)面小(xiao)編就(jiu)這些(xie)(xie)問題做簡單(dan)介(jie)紹。

　　什么是電源適配器?定義?

　　電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)適(shi)(shi)配(pei)(pei)器(qi)(qi)(qi)是(shi)小型(xing)便攜式電(dian)(dian)(dian)(dian)子(zi)(zi)設備(bei)及電(dian)(dian)(dian)(dian)子(zi)(zi)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)的(de)供電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)變換(huan)設備(bei)，一(yi)(yi)般由外(wai)殼(ke)、電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)變壓(ya)器(qi)(qi)(qi)和整(zheng)流(liu)(liu)電(dian)(dian)(dian)(dian)路組成，按其輸入(ru)(ru)類型(xing)可分(fen)為(wei)(wei)交流(liu)(liu)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)適(shi)(shi)配(pei)(pei)器(qi)(qi)(qi)和直流(liu)(liu)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)適(shi)(shi)配(pei)(pei)器(qi)(qi)(qi);按連接方(fang)式可分(fen)為(wei)(wei)插墻(qiang)式電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)適(shi)(shi)配(pei)(pei)器(qi)(qi)(qi)和桌(zhuo)面(mian)式電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)適(shi)(shi)配(pei)(pei)器(qi)(qi)(qi)。廣泛配(pei)(pei)套(tao)于電(dian)(dian)(dian)(dian)話(hua)子(zi)(zi)母機、游戲(xi)機、語言復(fu)讀機、隨身(shen)聽(ting)、筆記(ji)本計(ji)算(suan)機、蜂(feng)窩電(dian)(dian)(dian)(dian)話(hua)等設備(bei)中(zhong)。在電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)適(shi)(shi)配(pei)(pei)器(qi)(qi)(qi)上都(dou)有(you)一(yi)(yi)個(ge)銘(ming)牌，上面(mian)標(biao)示著(zhu)功(gong)率，輸入(ru)(ru)輸出(chu)電(dian)(dian)(dian)(dian)壓(ya)和電(dian)(dian)(dian)(dian)流(liu)(liu)量等指標(biao)，特別(bie)要注意輸入(ru)(ru)電(dian)(dian)(dian)(dian)壓(ya)的(de)范(fan)圍(wei)，這(zhe)就(jiu)是(shi)所謂(wei)的(de)“旅行電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)適(shi)(shi)配(pei)(pei)器(qi)(qi)(qi)”，如果到市電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓(ya)只有(you)100V的(de)國家時，這(zhe)個(ge)特性(xing)就(jiu)很有(you)用了，有(you)些水貨筆記(ji)本電(dian)(dian)(dian)(dian)腦(nao)是(shi)只在原產地銷(xiao)售的(de)，沒有(you)這(zhe)種設計(ji)，甚至只有(you)100V的(de)單一(yi)(yi)輸入(ru)(ru)電(dian)(dian)(dian)(dian)壓(ya)，在我國的(de)220V市電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓(ya)下插上就(jiu)會燒(shao)毀(hui)。

　　電(dian)(dian)源(yuan)適(shi)配(pei)器的(de)(de)(de)(de)作用(yong)就(jiu)是提(ti)供設(she)(she)備(bei)正(zheng)常工作所需要(yao)(yao)的(de)(de)(de)(de)能量。就(jiu)是給設(she)(she)備(bei)供電(dian)(dian)。有(you)的(de)(de)(de)(de)外置(zhi)(zhi)有(you)的(de)(de)(de)(de)內(nei)置(zhi)(zhi)，與設(she)(she)備(bei)的(de)(de)(de)(de)應用(yong)和(he)設(she)(she)計者有(you)關。 因(yin)為(wei)電(dian)(dian)源(yuan)適(shi)配(pei)器上(shang)有(you)相應的(de)(de)(de)(de)過(guo)溫保(bao)護功能，因(yin)此使用(yong)電(dian)(dian)源(yuan)適(shi)配(pei)器可(ke)以(yi)(yi)保(bao)護設(she)(she)備(bei)不受高溫的(de)(de)(de)(de)損害，穩(wen)定(ding)可(ke)靠的(de)(de)(de)(de)工作，同時具有(you)過(guo)流(liu)、過(guo)壓、過(guo)載保(bao)護功能，使設(she)(she)備(bei)不會因(yin)為(wei)電(dian)(dian)流(liu)、電(dian)(dian)壓等的(de)(de)(de)(de)波動而損壞。外置(zhi)(zhi)的(de)(de)(de)(de)電(dian)(dian)源(yuan)適(shi)配(pei)器使用(yong)比(bi)較靈活，只要(yao)(yao)可(ke)以(yi)(yi)符合設(she)(she)備(bei)要(yao)(yao)求的(de)(de)(de)(de)參數，就(jiu)可(ke)以(yi)(yi)使用(yong)同一(yi)個適(shi)配(pei)器。不過(guo)為(wei)保(bao)證設(she)(she)備(bei)的(de)(de)(de)(de)正(zheng)常運行，選(xuan)擇時一(yi)定(ding)要(yao)(yao)選(xuan)擇正(zheng)規廠家(jia)生產(chan)的(de)(de)(de)(de)電(dian)(dian)源(yuan)適(shi)配(pei)器。
