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(yuan)適配(pei)(pei)(pei)器(qi)的(de)(de)(de)應用(yong)(yong)極為(wei)廣泛，日(ri)常生(sheng)活用(yong)(yong)的(de)(de)(de)電(dian)(dian)(dian)冰箱、洗衣機(ji)、空氣凈(jing)化(hua)器(qi)、家里的(de)(de)(de)LED燈具和照(zhao)明設備(bei)(bei)、數(shu)碼相機(ji)，座機(ji)電(dian)(dian)(dian)話、電(dian)(dian)(dian)腦、筆記(ji)本等。除了(le)我們日(ri)常的(de)(de)(de)所(suo)見到的(de)(de)(de)這些(xie)東西以(yi)外(wai)，電(dian)(dian)(dian)源(yuan)適配(pei)(pei)(pei)器(qi)還應用(yong)(yong)在一些(xie)比較大的(de)(de)(de)設備(bei)(bei)上(shang)面。比如說數(shu)控(kong)機(ji)床、工業自動化(hua)控(kong)制系統、電(dian)(dian)(dian)力(li)設備(bei)(bei)和醫療設備(bei)(bei)上(shang)。在高校做(zuo)科研的(de)(de)(de)時候所(suo)用(yong)(yong)的(de)(de)(de)科研設備(bei)(bei)也有涉及電(dian)(dian)(dian)源(yuan)適配(pei)(pei)(pei)器(qi)。

　　有很多人(ren)把(ba)電(dian)(dian)源適(shi)配(pei)器(qi)(qi)(qi)和電(dian)(dian)池的(de)作用(yong)搞混了(le)(le)。其實這兩(liang)者(zhe)是(shi)有著本(ben)質區別的(de)。電(dian)(dian)池是(shi)用(yong)來儲備電(dian)(dian)量的(de)，而電(dian)(dian)源適(shi)配(pei)器(qi)(qi)(qi)是(shi)電(dian)(dian)源到(dao)設備，到(dao)電(dian)(dian)池之(zhi)間的(de)一(yi)(yi)個轉換系統(tong)。如(ru)果沒(mei)有電(dian)(dian)源適(shi)配(pei)器(qi)(qi)(qi)的(de)話，一(yi)(yi)旦電(dian)(dian)壓不穩，我(wo)們的(de)電(dian)(dian)腦、筆記本(ben)、電(dian)(dian)視等(deng)(deng)就會被燒掉。所以(yi)說有了(le)(le)電(dian)(dian)源適(shi)配(pei)器(qi)(qi)(qi)對(dui)我(wo)們的(de)家用(yong)電(dian)(dian)器(qi)(qi)(qi)來說是(shi)一(yi)(yi)個很好的(de)保護，同(tong)時也提高了(le)(le)電(dian)(dian)器(qi)(qi)(qi)的(de)安全性能。對(dui)我(wo)們自身身體也起到(dao)保護，試想一(yi)(yi)下如(ru)果我(wo)們的(de)電(dian)(dian)器(qi)(qi)(qi)沒(mei)有電(dian)(dian)源適(shi)配(pei)器(qi)(qi)(qi)的(de)話，一(yi)(yi)旦電(dian)(dian)流過大(da)會突然中(zhong)斷，就有可(ke)能引(yin)起電(dian)(dian)器(qi)(qi)(qi)爆炸(zha)或(huo)者(zhe)起火(huo)花等(deng)(deng)，造成的(de)爆破(po)或(huo)者(zhe)火(huo)災(zai)，對(dui)我(wo)們的(de)生(sheng)命健康都有著很大(da)的(de)威脅(xie)。可(ke)以(yi)說有了(le)(le)電(dian)(dian)源適(shi)配(pei)器(qi)(qi)(qi)就相當于給我(wo)們的(de)家用(yong)電(dian)(dian)器(qi)(qi)(qi)上(shang)了(le)(le)保險。再也不用(yong)擔心那些意外事故了(le)(le)。
