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)源適(shi)配器(qi)的(de)(de)應(ying)用極(ji)為廣泛，日常生活用的(de)(de)電(dian)冰(bing)箱、洗衣機(ji)、空(kong)氣凈(jing)化器(qi)、家里的(de)(de)LED燈具和照明設(she)備(bei)、數碼相機(ji)，座機(ji)電(dian)話、電(dian)腦、筆記(ji)本等。除了我們日常的(de)(de)所見(jian)到的(de)(de)這些東西以外，電(dian)源適(shi)配器(qi)還(huan)應(ying)用在(zai)一些比較(jiao)大的(de)(de)設(she)備(bei)上面。比如說數控機(ji)床、工(gong)業自動化控制(zhi)系統(tong)、電(dian)力設(she)備(bei)和醫療(liao)設(she)備(bei)上。在(zai)高(gao)校做科研的(de)(de)時(shi)候(hou)所用的(de)(de)科研設(she)備(bei)也有(you)涉及(ji)電(dian)源適(shi)配器(qi)。

　　有(you)很(hen)多人把電(dian)(dian)(dian)(dian)源(yuan)(yuan)適配(pei)器(qi)(qi)和電(dian)(dian)(dian)(dian)池(chi)的(de)作用(yong)(yong)搞(gao)混了(le)。其實這兩者(zhe)是有(you)著(zhu)本質區別的(de)。電(dian)(dian)(dian)(dian)池(chi)是用(yong)(yong)來儲備(bei)電(dian)(dian)(dian)(dian)量的(de)，而電(dian)(dian)(dian)(dian)源(yuan)(yuan)適配(pei)器(qi)(qi)是電(dian)(dian)(dian)(dian)源(yuan)(yuan)到(dao)設(she)備(bei)，到(dao)電(dian)(dian)(dian)(dian)池(chi)之間(jian)的(de)一個轉換系(xi)統(tong)。如(ru)果沒有(you)電(dian)(dian)(dian)(dian)源(yuan)(yuan)適配(pei)器(qi)(qi)的(de)話(hua)，一旦電(dian)(dian)(dian)(dian)壓不穩，我(wo)們的(de)電(dian)(dian)(dian)(dian)腦(nao)、筆記本、電(dian)(dian)(dian)(dian)視等就(jiu)會被燒掉。所以(yi)說有(you)了(le)電(dian)(dian)(dian)(dian)源(yuan)(yuan)適配(pei)器(qi)(qi)對(dui)我(wo)們的(de)家用(yong)(yong)電(dian)(dian)(dian)(dian)器(qi)(qi)來說是一個很(hen)好的(de)保(bao)護(hu)，同(tong)時也(ye)(ye)提高(gao)了(le)電(dian)(dian)(dian)(dian)器(qi)(qi)的(de)安(an)全(quan)性能(neng)。對(dui)我(wo)們自身(shen)身(shen)體(ti)也(ye)(ye)起(qi)到(dao)保(bao)護(hu)，試(shi)想(xiang)一下如(ru)果我(wo)們的(de)電(dian)(dian)(dian)(dian)器(qi)(qi)沒有(you)電(dian)(dian)(dian)(dian)源(yuan)(yuan)適配(pei)器(qi)(qi)的(de)話(hua)，一旦電(dian)(dian)(dian)(dian)流過(guo)大會突然(ran)中斷，就(jiu)有(you)可能(neng)引起(qi)電(dian)(dian)(dian)(dian)器(qi)(qi)爆炸或(huo)者(zhe)起(qi)火(huo)花等，造成的(de)爆破或(huo)者(zhe)火(huo)災，對(dui)我(wo)們的(de)生命健康都有(you)著(zhu)很(hen)大的(de)威脅(xie)。可以(yi)說有(you)了(le)電(dian)(dian)(dian)(dian)源(yuan)(yuan)適配(pei)器(qi)(qi)就(jiu)相當于給我(wo)們的(de)家用(yong)(yong)電(dian)(dian)(dian)(dian)器(qi)(qi)上了(le)保(bao)險。再也(ye)(ye)不用(yong)(yong)擔(dan)心那些(xie)意外事故了(le)。
