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)(dian)源適(shi)(shi)配(pei)(pei)器(qi)的(de)(de)應用極為廣泛，日(ri)(ri)常生活用的(de)(de)電(dian)(dian)(dian)冰箱、洗衣機(ji)、空氣凈化器(qi)、家里(li)的(de)(de)LED燈具和照明設(she)(she)備(bei)、數碼(ma)相(xiang)機(ji)，座機(ji)電(dian)(dian)(dian)話(hua)、電(dian)(dian)(dian)腦、筆記本等。除了我們日(ri)(ri)常的(de)(de)所(suo)見(jian)到的(de)(de)這些(xie)東西以外(wai)，電(dian)(dian)(dian)源適(shi)(shi)配(pei)(pei)器(qi)還應用在(zai)(zai)一(yi)些(xie)比較大的(de)(de)設(she)(she)備(bei)上面。比如(ru)說數控(kong)機(ji)床(chuang)、工(gong)業自動化控(kong)制系(xi)統、電(dian)(dian)(dian)力(li)設(she)(she)備(bei)和醫療(liao)設(she)(she)備(bei)上。在(zai)(zai)高校(xiao)做(zuo)科研(yan)的(de)(de)時候所(suo)用的(de)(de)科研(yan)設(she)(she)備(bei)也有涉及電(dian)(dian)(dian)源適(shi)(shi)配(pei)(pei)器(qi)。

　　有(you)很多人把(ba)電(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)配(pei)器(qi)和電(dian)(dian)(dian)(dian)(dian)池的(de)(de)作用搞混了(le)(le)(le)。其(qi)實這兩者是(shi)(shi)有(you)著(zhu)本質區別的(de)(de)。電(dian)(dian)(dian)(dian)(dian)池是(shi)(shi)用來(lai)儲備(bei)電(dian)(dian)(dian)(dian)(dian)量的(de)(de)，而電(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)配(pei)器(qi)是(shi)(shi)電(dian)(dian)(dian)(dian)(dian)源(yuan)到設(she)備(bei)，到電(dian)(dian)(dian)(dian)(dian)池之間的(de)(de)一(yi)(yi)(yi)(yi)(yi)個轉換系(xi)統。如果沒(mei)有(you)電(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)配(pei)器(qi)的(de)(de)話，一(yi)(yi)(yi)(yi)(yi)旦(dan)電(dian)(dian)(dian)(dian)(dian)壓不穩，我們(men)的(de)(de)電(dian)(dian)(dian)(dian)(dian)腦、筆記本、電(dian)(dian)(dian)(dian)(dian)視等(deng)就會(hui)被燒掉(diao)。所(suo)以說有(you)了(le)(le)(le)電(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)配(pei)器(qi)對(dui)我們(men)的(de)(de)家用電(dian)(dian)(dian)(dian)(dian)器(qi)來(lai)說是(shi)(shi)一(yi)(yi)(yi)(yi)(yi)個很好的(de)(de)保(bao)護，同時(shi)也提高了(le)(le)(le)電(dian)(dian)(dian)(dian)(dian)器(qi)的(de)(de)安(an)全性能。對(dui)我們(men)自(zi)身身體也起到保(bao)護，試想(xiang)一(yi)(yi)(yi)(yi)(yi)下如果我們(men)的(de)(de)電(dian)(dian)(dian)(dian)(dian)器(qi)沒(mei)有(you)電(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)配(pei)器(qi)的(de)(de)話，一(yi)(yi)(yi)(yi)(yi)旦(dan)電(dian)(dian)(dian)(dian)(dian)流過大會(hui)突(tu)然(ran)中(zhong)斷，就有(you)可能引起電(dian)(dian)(dian)(dian)(dian)器(qi)爆炸或(huo)者起火花等(deng)，造成(cheng)的(de)(de)爆破或(huo)者火災，對(dui)我們(men)的(de)(de)生命健康都有(you)著(zhu)很大的(de)(de)威(wei)脅。可以說有(you)了(le)(le)(le)電(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)配(pei)器(qi)就相(xiang)當于給我們(men)的(de)(de)家用電(dian)(dian)(dian)(dian)(dian)器(qi)上了(le)(le)(le)保(bao)險。再也不用擔心(xin)那些(xie)意(yi)外(wai)事(shi)故了(le)(le)(le)。
