什么是電源適配器?使用(yong)(yong)電源適配(pei)器相對有哪些(xie)作用(yong)(yong)呢?在什(shen)么情況下(xia)用(yong)(yong)外置(zhi)的電源適配(pei)器比較(jiao)好呢?下(xia)面小編就這些(xie)問題做簡(jian)單介紹。

　　什么是電源適配器?定義?

　　電(dian)(dian)(dian)(dian)源(yuan)(yuan)適配(pei)(pei)(pei)器(qi)(qi)(qi)是(shi)(shi)小(xiao)型便攜式電(dian)(dian)(dian)(dian)子(zi)設(she)備(bei)及(ji)電(dian)(dian)(dian)(dian)子(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)變(bian)換(huan)設(she)備(bei)，一般由外殼、電(dian)(dian)(dian)(dian)源(yuan)(yuan)變(bian)壓(ya)器(qi)(qi)(qi)和(he)整流電(dian)(dian)(dian)(dian)路組成，按(an)其輸入類型可(ke)分為交流電(dian)(dian)(dian)(dian)源(yuan)(yuan)適配(pei)(pei)(pei)器(qi)(qi)(qi)和(he)直流電(dian)(dian)(dian)(dian)源(yuan)(yuan)適配(pei)(pei)(pei)器(qi)(qi)(qi);按(an)連(lian)接方式可(ke)分為插(cha)墻式電(dian)(dian)(dian)(dian)源(yuan)(yuan)適配(pei)(pei)(pei)器(qi)(qi)(qi)和(he)桌面式電(dian)(dian)(dian)(dian)源(yuan)(yuan)適配(pei)(pei)(pei)器(qi)(qi)(qi)。廣泛配(pei)(pei)(pei)套于電(dian)(dian)(dian)(dian)話子(zi)母機(ji)、游戲機(ji)、語(yu)言復讀機(ji)、隨身(shen)聽(ting)、筆(bi)記本計算機(ji)、蜂(feng)窩電(dian)(dian)(dian)(dian)話等設(she)備(bei)中(zhong)。在(zai)(zai)電(dian)(dian)(dian)(dian)源(yuan)(yuan)適配(pei)(pei)(pei)器(qi)(qi)(qi)上(shang)都有(you)(you)一個銘(ming)牌，上(shang)面標(biao)示著功(gong)率，輸入輸出(chu)電(dian)(dian)(dian)(dian)壓(ya)和(he)電(dian)(dian)(dian)(dian)流量等指標(biao)，特(te)(te)別要注(zhu)意輸入電(dian)(dian)(dian)(dian)壓(ya)的(de)范圍，這就(jiu)是(shi)(shi)所謂的(de)“旅行電(dian)(dian)(dian)(dian)源(yuan)(yuan)適配(pei)(pei)(pei)器(qi)(qi)(qi)”，如果到市(shi)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓(ya)只有(you)(you)100V的(de)國家時(shi)，這個特(te)(te)性(xing)就(jiu)很有(you)(you)用了，有(you)(you)些水貨筆(bi)記本電(dian)(dian)(dian)(dian)腦是(shi)(shi)只在(zai)(zai)原產地銷售的(de)，沒有(you)(you)這種設(she)計，甚至只有(you)(you)100V的(de)單一輸入電(dian)(dian)(dian)(dian)壓(ya)，在(zai)(zai)我國的(de)220V市(shi)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓(ya)下插(cha)上(shang)就(jiu)會燒毀。

　　電(dian)源適(shi)(shi)(shi)配器的(de)(de)(de)(de)作(zuo)用就(jiu)是提(ti)供設(she)(she)備(bei)(bei)正常工作(zuo)所需要的(de)(de)(de)(de)能量。就(jiu)是給設(she)(she)備(bei)(bei)供電(dian)。有(you)的(de)(de)(de)(de)外(wai)置(zhi)有(you)的(de)(de)(de)(de)內(nei)置(zhi)，與設(she)(she)備(bei)(bei)的(de)(de)(de)(de)應用和設(she)(she)計者(zhe)有(you)關。 因(yin)為(wei)(wei)電(dian)源適(shi)(shi)(shi)配器上(shang)有(you)相應的(de)(de)(de)(de)過(guo)溫保(bao)護(hu)(hu)功能，因(yin)此使(shi)用電(dian)源適(shi)(shi)(shi)配器可(ke)以保(bao)護(hu)(hu)設(she)(she)備(bei)(bei)不受高溫的(de)(de)(de)(de)損害，穩定(ding)(ding)可(ke)靠(kao)的(de)(de)(de)(de)工作(zuo)，同時具有(you)過(guo)流(liu)、過(guo)壓、過(guo)載保(bao)護(hu)(hu)功能，使(shi)設(she)(she)備(bei)(bei)不會因(yin)為(wei)(wei)電(dian)流(liu)、電(dian)壓等的(de)(de)(de)(de)波(bo)動而損壞。外(wai)置(zhi)的(de)(de)(de)(de)電(dian)源適(shi)(shi)(shi)配器使(shi)用比(bi)較靈(ling)活，只要可(ke)以符(fu)合設(she)(she)備(bei)(bei)要求的(de)(de)(de)(de)參(can)數，就(jiu)可(ke)以使(shi)用同一個適(shi)(shi)(shi)配器。不過(guo)為(wei)(wei)保(bao)證設(she)(she)備(bei)(bei)的(de)(de)(de)(de)正常運(yun)行(xing)，選擇(ze)時一定(ding)(ding)要選擇(ze)正規廠家生產的(de)(de)(de)(de)電(dian)源適(shi)(shi)(shi)配器。
