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)配器(qi)的(de)(de)應用極為廣(guang)泛，日常生活用的(de)(de)電(dian)(dian)(dian)冰(bing)箱(xiang)、洗衣機(ji)、空氣凈(jing)化(hua)器(qi)、家(jia)里的(de)(de)LED燈具和(he)(he)照明設備(bei)(bei)(bei)、數(shu)碼相機(ji)，座機(ji)電(dian)(dian)(dian)話、電(dian)(dian)(dian)腦、筆記本等。除(chu)了(le)我們(men)日常的(de)(de)所(suo)見到的(de)(de)這些(xie)東西以外(wai)，電(dian)(dian)(dian)源適(shi)配器(qi)還應用在(zai)一些(xie)比較大的(de)(de)設備(bei)(bei)(bei)上面。比如說數(shu)控(kong)機(ji)床、工業自(zi)動(dong)化(hua)控(kong)制系統、電(dian)(dian)(dian)力設備(bei)(bei)(bei)和(he)(he)醫療設備(bei)(bei)(bei)上。在(zai)高校做(zuo)科研的(de)(de)時(shi)候所(suo)用的(de)(de)科研設備(bei)(bei)(bei)也有涉及(ji)電(dian)(dian)(dian)源適(shi)配器(qi)。

　　有(you)(you)(you)很多人(ren)把電(dian)(dian)(dian)源(yuan)適(shi)(shi)配(pei)器和(he)電(dian)(dian)(dian)池(chi)的(de)(de)(de)作用(yong)(yong)搞混了(le)(le)(le)。其(qi)實這兩者是(shi)(shi)(shi)有(you)(you)(you)著本(ben)質區別的(de)(de)(de)。電(dian)(dian)(dian)池(chi)是(shi)(shi)(shi)用(yong)(yong)來儲備電(dian)(dian)(dian)量的(de)(de)(de)，而電(dian)(dian)(dian)源(yuan)適(shi)(shi)配(pei)器是(shi)(shi)(shi)電(dian)(dian)(dian)源(yuan)到設備，到電(dian)(dian)(dian)池(chi)之(zhi)間(jian)的(de)(de)(de)一個轉換系統。如果(guo)沒有(you)(you)(you)電(dian)(dian)(dian)源(yuan)適(shi)(shi)配(pei)器的(de)(de)(de)話(hua)，一旦電(dian)(dian)(dian)壓(ya)不(bu)穩，我(wo)們的(de)(de)(de)電(dian)(dian)(dian)腦、筆記本(ben)、電(dian)(dian)(dian)視等就(jiu)會被燒掉。所以(yi)說有(you)(you)(you)了(le)(le)(le)電(dian)(dian)(dian)源(yuan)適(shi)(shi)配(pei)器對(dui)(dui)我(wo)們的(de)(de)(de)家(jia)用(yong)(yong)電(dian)(dian)(dian)器來說是(shi)(shi)(shi)一個很好的(de)(de)(de)保護(hu)，同時(shi)也提高了(le)(le)(le)電(dian)(dian)(dian)器的(de)(de)(de)安全性能。對(dui)(dui)我(wo)們自身(shen)身(shen)體也起到保護(hu)，試(shi)想(xiang)一下如果(guo)我(wo)們的(de)(de)(de)電(dian)(dian)(dian)器沒有(you)(you)(you)電(dian)(dian)(dian)源(yuan)適(shi)(shi)配(pei)器的(de)(de)(de)話(hua)，一旦電(dian)(dian)(dian)流過大(da)(da)會突(tu)然中斷(duan)，就(jiu)有(you)(you)(you)可能引(yin)起電(dian)(dian)(dian)器爆炸或者起火(huo)花等，造(zao)成的(de)(de)(de)爆破或者火(huo)災，對(dui)(dui)我(wo)們的(de)(de)(de)生命健康都有(you)(you)(you)著很大(da)(da)的(de)(de)(de)威脅(xie)。可以(yi)說有(you)(you)(you)了(le)(le)(le)電(dian)(dian)(dian)源(yuan)適(shi)(shi)配(pei)器就(jiu)相當(dang)于給我(wo)們的(de)(de)(de)家(jia)用(yong)(yong)電(dian)(dian)(dian)器上了(le)(le)(le)保險。再也不(bu)用(yong)(yong)擔(dan)心那些意外事(shi)故了(le)(le)(le)。
