什么是電源適配器?使用(yong)(yong)電源(yuan)(yuan)適配器(qi)相對(dui)有哪(na)些作用(yong)(yong)呢?在(zai)什么情(qing)況下(xia)用(yong)(yong)外置(zhi)的(de)電源(yuan)(yuan)適配器(qi)比較好呢?下(xia)面小(xiao)編就這些問題做簡單介(jie)紹。

　　什么是電源適配器?定義?

　　電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)適(shi)配器(qi)是(shi)(shi)小(xiao)型(xing)便攜式(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)設(she)(she)(she)備及(ji)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)的(de)(de)供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)變(bian)換設(she)(she)(she)備，一(yi)般由外殼、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)變(bian)壓(ya)(ya)器(qi)和(he)整流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路組成(cheng)，按其輸(shu)(shu)入類(lei)型(xing)可分為交流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)適(shi)配器(qi)和(he)直流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)適(shi)配器(qi);按連(lian)接方式(shi)可分為插(cha)墻式(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)適(shi)配器(qi)和(he)桌面(mian)式(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)適(shi)配器(qi)。廣泛配套于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)話子(zi)母機(ji)、游(you)戲機(ji)、語言復(fu)讀機(ji)、隨身聽、筆記本計算機(ji)、蜂窩電(dian)(dian)(dian)(dian)(dian)(dian)(dian)話等設(she)(she)(she)備中。在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)適(shi)配器(qi)上(shang)都有(you)一(yi)個銘牌，上(shang)面(mian)標(biao)示(shi)著功(gong)率(lv)，輸(shu)(shu)入輸(shu)(shu)出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)和(he)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)量等指標(biao)，特(te)別要(yao)注意輸(shu)(shu)入電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)的(de)(de)范圍，這(zhe)(zhe)就是(shi)(shi)所(suo)謂(wei)的(de)(de)“旅(lv)行(xing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)適(shi)配器(qi)”，如果到(dao)市電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)只(zhi)有(you)100V的(de)(de)國家時(shi)，這(zhe)(zhe)個特(te)性就很(hen)有(you)用了，有(you)些水(shui)貨(huo)筆記本電(dian)(dian)(dian)(dian)(dian)(dian)(dian)腦是(shi)(shi)只(zhi)在(zai)原產地銷售(shou)的(de)(de)，沒有(you)這(zhe)(zhe)種(zhong)設(she)(she)(she)計，甚(shen)至只(zhi)有(you)100V的(de)(de)單一(yi)輸(shu)(shu)入電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)，在(zai)我國的(de)(de)220V市電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)下插(cha)上(shang)就會燒毀(hui)。

　　電源(yuan)(yuan)適配(pei)(pei)器(qi)的(de)(de)(de)作用(yong)就(jiu)是提供設(she)(she)備(bei)正(zheng)常工(gong)作所需要(yao)(yao)的(de)(de)(de)能(neng)量。就(jiu)是給設(she)(she)備(bei)供電。有(you)的(de)(de)(de)外置有(you)的(de)(de)(de)內(nei)置，與(yu)設(she)(she)備(bei)的(de)(de)(de)應用(yong)和設(she)(she)計者有(you)關。 因為電源(yuan)(yuan)適配(pei)(pei)器(qi)上(shang)有(you)相應的(de)(de)(de)過(guo)(guo)(guo)溫保(bao)護(hu)功能(neng)，因此使(shi)用(yong)電源(yuan)(yuan)適配(pei)(pei)器(qi)可(ke)(ke)以(yi)保(bao)護(hu)設(she)(she)備(bei)不受高溫的(de)(de)(de)損害，穩定可(ke)(ke)靠的(de)(de)(de)工(gong)作，同時具有(you)過(guo)(guo)(guo)流、過(guo)(guo)(guo)壓(ya)、過(guo)(guo)(guo)載(zai)保(bao)護(hu)功能(neng)，使(shi)設(she)(she)備(bei)不會因為電流、電壓(ya)等的(de)(de)(de)波(bo)動(dong)而損壞(huai)。外置的(de)(de)(de)電源(yuan)(yuan)適配(pei)(pei)器(qi)使(shi)用(yong)比較靈活(huo)，只要(yao)(yao)可(ke)(ke)以(yi)符合設(she)(she)備(bei)要(yao)(yao)求的(de)(de)(de)參(can)數，就(jiu)可(ke)(ke)以(yi)使(shi)用(yong)同一個適配(pei)(pei)器(qi)。不過(guo)(guo)(guo)為保(bao)證設(she)(she)備(bei)的(de)(de)(de)正(zheng)常運行(xing)，選擇(ze)(ze)時一定要(yao)(yao)選擇(ze)(ze)正(zheng)規(gui)廠家生(sheng)產的(de)(de)(de)電源(yuan)(yuan)適配(pei)(pei)器(qi)。
