什么是電源適配器?使(shi)用電源(yuan)適配器相(xiang)對有(you)哪些(xie)作用呢?在什(shen)么情況(kuang)下用外置(zhi)的(de)電源(yuan)適配器比較(jiao)好呢?下面小編就這(zhe)些(xie)問題做簡單介紹。

　　什么是電源適配器?定義?

　　電(dian)(dian)(dian)源(yuan)(yuan)適(shi)配(pei)(pei)器是(shi)小型便攜(xie)式(shi)(shi)(shi)電(dian)(dian)(dian)子設備及電(dian)(dian)(dian)子電(dian)(dian)(dian)器的(de)(de)(de)(de)供電(dian)(dian)(dian)電(dian)(dian)(dian)源(yuan)(yuan)變換設備，一(yi)般由外殼、電(dian)(dian)(dian)源(yuan)(yuan)變壓(ya)器和整流電(dian)(dian)(dian)路組成，按其輸(shu)(shu)(shu)入(ru)類型可分為交流電(dian)(dian)(dian)源(yuan)(yuan)適(shi)配(pei)(pei)器和直流電(dian)(dian)(dian)源(yuan)(yuan)適(shi)配(pei)(pei)器;按連接方式(shi)(shi)(shi)可分為插墻式(shi)(shi)(shi)電(dian)(dian)(dian)源(yuan)(yuan)適(shi)配(pei)(pei)器和桌面式(shi)(shi)(shi)電(dian)(dian)(dian)源(yuan)(yuan)適(shi)配(pei)(pei)器。廣泛配(pei)(pei)套(tao)于電(dian)(dian)(dian)話子母機(ji)、游戲機(ji)、語言復(fu)讀機(ji)、隨身(shen)聽、筆記(ji)本計算機(ji)、蜂窩電(dian)(dian)(dian)話等(deng)(deng)設備中。在(zai)電(dian)(dian)(dian)源(yuan)(yuan)適(shi)配(pei)(pei)器上都(dou)有一(yi)個(ge)銘牌(pai)，上面標示著功率，輸(shu)(shu)(shu)入(ru)輸(shu)(shu)(shu)出電(dian)(dian)(dian)壓(ya)和電(dian)(dian)(dian)流量等(deng)(deng)指標，特(te)別要注(zhu)意(yi)輸(shu)(shu)(shu)入(ru)電(dian)(dian)(dian)壓(ya)的(de)(de)(de)(de)范圍，這就(jiu)是(shi)所謂的(de)(de)(de)(de)“旅(lv)行電(dian)(dian)(dian)源(yuan)(yuan)適(shi)配(pei)(pei)器”，如果(guo)到市電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)只(zhi)(zhi)有100V的(de)(de)(de)(de)國(guo)家(jia)時(shi)，這個(ge)特(te)性就(jiu)很有用了，有些水貨筆記(ji)本電(dian)(dian)(dian)腦(nao)是(shi)只(zhi)(zhi)在(zai)原產地銷售(shou)的(de)(de)(de)(de)，沒有這種設計，甚至只(zhi)(zhi)有100V的(de)(de)(de)(de)單(dan)一(yi)輸(shu)(shu)(shu)入(ru)電(dian)(dian)(dian)壓(ya)，在(zai)我國(guo)的(de)(de)(de)(de)220V市電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)下插上就(jiu)會(hui)燒毀。

　　電(dian)(dian)源(yuan)適(shi)(shi)配(pei)器(qi)(qi)(qi)的(de)(de)(de)作(zuo)用(yong)(yong)就是提供(gong)(gong)設備(bei)正(zheng)常(chang)工作(zuo)所(suo)需要的(de)(de)(de)能量。就是給設備(bei)供(gong)(gong)電(dian)(dian)。有的(de)(de)(de)外置(zhi)(zhi)有的(de)(de)(de)內置(zhi)(zhi)，與設備(bei)的(de)(de)(de)應用(yong)(yong)和設計者有關(guan)。 因(yin)為電(dian)(dian)源(yuan)適(shi)(shi)配(pei)器(qi)(qi)(qi)上有相應的(de)(de)(de)過(guo)溫(wen)保(bao)護功(gong)能，因(yin)此使用(yong)(yong)電(dian)(dian)源(yuan)適(shi)(shi)配(pei)器(qi)(qi)(qi)可(ke)以保(bao)護設備(bei)不(bu)(bu)受高溫(wen)的(de)(de)(de)損害，穩定可(ke)靠的(de)(de)(de)工作(zuo)，同時(shi)具有過(guo)流、過(guo)壓、過(guo)載保(bao)護功(gong)能，使設備(bei)不(bu)(bu)會因(yin)為電(dian)(dian)流、電(dian)(dian)壓等的(de)(de)(de)波動而損壞(huai)。外置(zhi)(zhi)的(de)(de)(de)電(dian)(dian)源(yuan)適(shi)(shi)配(pei)器(qi)(qi)(qi)使用(yong)(yong)比(bi)較靈活，只要可(ke)以符合設備(bei)要求的(de)(de)(de)參數，就可(ke)以使用(yong)(yong)同一個適(shi)(shi)配(pei)器(qi)(qi)(qi)。不(bu)(bu)過(guo)為保(bao)證設備(bei)的(de)(de)(de)正(zheng)常(chang)運行(xing)，選擇(ze)時(shi)一定要選擇(ze)正(zheng)規廠家(jia)生(sheng)產的(de)(de)(de)電(dian)(dian)源(yuan)適(shi)(shi)配(pei)器(qi)(qi)(qi)。
