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)(shi)配器(qi)(qi)的(de)應(ying)用(yong)(yong)極為廣泛，日常生活用(yong)(yong)的(de)電(dian)冰箱、洗衣(yi)機、空氣凈化器(qi)(qi)、家(jia)里的(de)LED燈(deng)具和照明設(she)備(bei)、數碼相機，座機電(dian)話、電(dian)腦、筆記本等。除了我們日常的(de)所(suo)見到的(de)這些東西(xi)以外(wai)，電(dian)源適(shi)(shi)配器(qi)(qi)還應(ying)用(yong)(yong)在(zai)一些比較大(da)的(de)設(she)備(bei)上面(mian)。比如(ru)說數控機床、工業自(zi)動化控制系統、電(dian)力(li)設(she)備(bei)和醫療設(she)備(bei)上。在(zai)高校做科(ke)研(yan)的(de)時候所(suo)用(yong)(yong)的(de)科(ke)研(yan)設(she)備(bei)也(ye)有(you)涉(she)及電(dian)源適(shi)(shi)配器(qi)(qi)。

　　有(you)很(hen)多人把電(dian)(dian)(dian)源(yuan)適(shi)配器(qi)和電(dian)(dian)(dian)池(chi)的(de)(de)(de)作用(yong)(yong)搞混了(le)(le)。其(qi)實這兩者(zhe)(zhe)是(shi)有(you)著(zhu)本質區別的(de)(de)(de)。電(dian)(dian)(dian)池(chi)是(shi)用(yong)(yong)來儲備(bei)電(dian)(dian)(dian)量(liang)的(de)(de)(de)，而電(dian)(dian)(dian)源(yuan)適(shi)配器(qi)是(shi)電(dian)(dian)(dian)源(yuan)到設(she)備(bei)，到電(dian)(dian)(dian)池(chi)之間的(de)(de)(de)一(yi)(yi)個(ge)轉(zhuan)換系統。如果沒(mei)有(you)電(dian)(dian)(dian)源(yuan)適(shi)配器(qi)的(de)(de)(de)話，一(yi)(yi)旦電(dian)(dian)(dian)壓不(bu)穩，我(wo)(wo)(wo)們(men)(men)的(de)(de)(de)電(dian)(dian)(dian)腦、筆記本、電(dian)(dian)(dian)視等就會(hui)被燒掉。所(suo)以說(shuo)有(you)了(le)(le)電(dian)(dian)(dian)源(yuan)適(shi)配器(qi)對(dui)我(wo)(wo)(wo)們(men)(men)的(de)(de)(de)家(jia)用(yong)(yong)電(dian)(dian)(dian)器(qi)來說(shuo)是(shi)一(yi)(yi)個(ge)很(hen)好的(de)(de)(de)保(bao)護，同(tong)時也(ye)提高(gao)了(le)(le)電(dian)(dian)(dian)器(qi)的(de)(de)(de)安全性能(neng)(neng)。對(dui)我(wo)(wo)(wo)們(men)(men)自身(shen)身(shen)體(ti)也(ye)起(qi)到保(bao)護，試(shi)想一(yi)(yi)下如果我(wo)(wo)(wo)們(men)(men)的(de)(de)(de)電(dian)(dian)(dian)器(qi)沒(mei)有(you)電(dian)(dian)(dian)源(yuan)適(shi)配器(qi)的(de)(de)(de)話，一(yi)(yi)旦電(dian)(dian)(dian)流過大會(hui)突然中斷，就有(you)可能(neng)(neng)引起(qi)電(dian)(dian)(dian)器(qi)爆(bao)炸或(huo)者(zhe)(zhe)起(qi)火花(hua)等，造成(cheng)的(de)(de)(de)爆(bao)破或(huo)者(zhe)(zhe)火災，對(dui)我(wo)(wo)(wo)們(men)(men)的(de)(de)(de)生命健康都有(you)著(zhu)很(hen)大的(de)(de)(de)威脅。可以說(shuo)有(you)了(le)(le)電(dian)(dian)(dian)源(yuan)適(shi)配器(qi)就相當于(yu)給我(wo)(wo)(wo)們(men)(men)的(de)(de)(de)家(jia)用(yong)(yong)電(dian)(dian)(dian)器(qi)上了(le)(le)保(bao)險。再也(ye)不(bu)用(yong)(yong)擔心那些意外事故了(le)(le)。
