隨著人類的進步，科技的發展。現每個的家庭中都有或大或小的電器，當然也離不開電源適配器輔助設備。

　　電(dian)(dian)源適配器(qi)的(de)(de)應(ying)用極為(wei)廣泛，日(ri)常(chang)生活用的(de)(de)電(dian)(dian)冰箱、洗衣(yi)機(ji)(ji)、空氣凈化(hua)(hua)器(qi)、家里的(de)(de)LED燈(deng)具和(he)照明(ming)設備、數碼相機(ji)(ji)，座機(ji)(ji)電(dian)(dian)話、電(dian)(dian)腦、筆記(ji)本等。除了我們日(ri)常(chang)的(de)(de)所見(jian)到(dao)的(de)(de)這些(xie)(xie)東西以外(wai)，電(dian)(dian)源適配器(qi)還應(ying)用在(zai)一些(xie)(xie)比較大的(de)(de)設備上面。比如說數控(kong)機(ji)(ji)床、工業自(zi)動(dong)化(hua)(hua)控(kong)制系統、電(dian)(dian)力設備和(he)醫療(liao)設備上。在(zai)高校做(zuo)科(ke)研的(de)(de)時候所用的(de)(de)科(ke)研設備也有涉(she)及(ji)電(dian)(dian)源適配器(qi)。

　　有(you)很多人把電(dian)(dian)(dian)(dian)源(yuan)(yuan)適配(pei)(pei)器(qi)(qi)(qi)和(he)電(dian)(dian)(dian)(dian)池(chi)的(de)(de)(de)(de)(de)作用搞(gao)混了(le)(le)(le)。其實(shi)這(zhe)兩者是(shi)(shi)有(you)著(zhu)本質區別的(de)(de)(de)(de)(de)。電(dian)(dian)(dian)(dian)池(chi)是(shi)(shi)用來(lai)儲備(bei)電(dian)(dian)(dian)(dian)量(liang)的(de)(de)(de)(de)(de)，而(er)電(dian)(dian)(dian)(dian)源(yuan)(yuan)適配(pei)(pei)器(qi)(qi)(qi)是(shi)(shi)電(dian)(dian)(dian)(dian)源(yuan)(yuan)到(dao)(dao)設備(bei)，到(dao)(dao)電(dian)(dian)(dian)(dian)池(chi)之間的(de)(de)(de)(de)(de)一(yi)個(ge)轉換系統。如果沒(mei)有(you)電(dian)(dian)(dian)(dian)源(yuan)(yuan)適配(pei)(pei)器(qi)(qi)(qi)的(de)(de)(de)(de)(de)話，一(yi)旦電(dian)(dian)(dian)(dian)壓不穩，我(wo)(wo)(wo)們(men)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)腦、筆(bi)記本、電(dian)(dian)(dian)(dian)視等就(jiu)會(hui)被燒掉。所以說有(you)了(le)(le)(le)電(dian)(dian)(dian)(dian)源(yuan)(yuan)適配(pei)(pei)器(qi)(qi)(qi)對(dui)我(wo)(wo)(wo)們(men)的(de)(de)(de)(de)(de)家用電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)來(lai)說是(shi)(shi)一(yi)個(ge)很好的(de)(de)(de)(de)(de)保(bao)護，同時也(ye)(ye)提高了(le)(le)(le)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)的(de)(de)(de)(de)(de)安全性能(neng)。對(dui)我(wo)(wo)(wo)們(men)自(zi)身身體也(ye)(ye)起(qi)到(dao)(dao)保(bao)護，試想一(yi)下如果我(wo)(wo)(wo)們(men)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)沒(mei)有(you)電(dian)(dian)(dian)(dian)源(yuan)(yuan)適配(pei)(pei)器(qi)(qi)(qi)的(de)(de)(de)(de)(de)話，一(yi)旦電(dian)(dian)(dian)(dian)流過大(da)會(hui)突然中斷，就(jiu)有(you)可能(neng)引起(qi)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)爆炸或者起(qi)火花等，造成(cheng)的(de)(de)(de)(de)(de)爆破或者火災，對(dui)我(wo)(wo)(wo)們(men)的(de)(de)(de)(de)(de)生命健(jian)康都有(you)著(zhu)很大(da)的(de)(de)(de)(de)(de)威脅(xie)。可以說有(you)了(le)(le)(le)電(dian)(dian)(dian)(dian)源(yuan)(yuan)適配(pei)(pei)器(qi)(qi)(qi)就(jiu)相當于(yu)給我(wo)(wo)(wo)們(men)的(de)(de)(de)(de)(de)家用電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)上(shang)了(le)(le)(le)保(bao)險。再也(ye)(ye)不用擔心那些意外(wai)事故了(le)(le)(le)。
