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(yuan)適配(pei)(pei)器的(de)(de)(de)應用極為廣泛，日常(chang)生活(huo)用的(de)(de)(de)電(dian)冰箱、洗(xi)衣機(ji)(ji)、空氣凈化器、家里的(de)(de)(de)LED燈具和(he)(he)照明設(she)(she)備(bei)(bei)、數碼相機(ji)(ji)，座機(ji)(ji)電(dian)話、電(dian)腦、筆記本(ben)等。除了我們日常(chang)的(de)(de)(de)所見到的(de)(de)(de)這些東西以外，電(dian)源(yuan)適配(pei)(pei)器還應用在一些比較大的(de)(de)(de)設(she)(she)備(bei)(bei)上面。比如說(shuo)數控(kong)機(ji)(ji)床、工業自動化控(kong)制系統、電(dian)力設(she)(she)備(bei)(bei)和(he)(he)醫療設(she)(she)備(bei)(bei)上。在高校做科研的(de)(de)(de)時候所用的(de)(de)(de)科研設(she)(she)備(bei)(bei)也有涉及(ji)電(dian)源(yuan)適配(pei)(pei)器。

　　有(you)(you)(you)(you)很(hen)多人把電(dian)(dian)(dian)(dian)源(yuan)適配器(qi)(qi)和電(dian)(dian)(dian)(dian)池的(de)(de)(de)(de)(de)(de)作用(yong)(yong)搞(gao)混了。其實這兩者(zhe)是有(you)(you)(you)(you)著本質區別的(de)(de)(de)(de)(de)(de)。電(dian)(dian)(dian)(dian)池是用(yong)(yong)來儲備電(dian)(dian)(dian)(dian)量(liang)的(de)(de)(de)(de)(de)(de)，而電(dian)(dian)(dian)(dian)源(yuan)適配器(qi)(qi)是電(dian)(dian)(dian)(dian)源(yuan)到設(she)備，到電(dian)(dian)(dian)(dian)池之間的(de)(de)(de)(de)(de)(de)一(yi)個(ge)轉換系統。如果(guo)沒有(you)(you)(you)(you)電(dian)(dian)(dian)(dian)源(yuan)適配器(qi)(qi)的(de)(de)(de)(de)(de)(de)話，一(yi)旦電(dian)(dian)(dian)(dian)壓不(bu)穩，我(wo)們(men)(men)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)腦、筆記本、電(dian)(dian)(dian)(dian)視等(deng)就(jiu)會被燒掉(diao)。所以說(shuo)有(you)(you)(you)(you)了電(dian)(dian)(dian)(dian)源(yuan)適配器(qi)(qi)對我(wo)們(men)(men)的(de)(de)(de)(de)(de)(de)家(jia)用(yong)(yong)電(dian)(dian)(dian)(dian)器(qi)(qi)來說(shuo)是一(yi)個(ge)很(hen)好(hao)的(de)(de)(de)(de)(de)(de)保(bao)護，同時(shi)也(ye)提(ti)高了電(dian)(dian)(dian)(dian)器(qi)(qi)的(de)(de)(de)(de)(de)(de)安(an)全性能。對我(wo)們(men)(men)自身身體也(ye)起到保(bao)護，試想一(yi)下如果(guo)我(wo)們(men)(men)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)器(qi)(qi)沒有(you)(you)(you)(you)電(dian)(dian)(dian)(dian)源(yuan)適配器(qi)(qi)的(de)(de)(de)(de)(de)(de)話，一(yi)旦電(dian)(dian)(dian)(dian)流過大會突然中斷，就(jiu)有(you)(you)(you)(you)可能引起電(dian)(dian)(dian)(dian)器(qi)(qi)爆炸或(huo)者(zhe)起火花(hua)等(deng)，造成的(de)(de)(de)(de)(de)(de)爆破或(huo)者(zhe)火災，對我(wo)們(men)(men)的(de)(de)(de)(de)(de)(de)生命健(jian)康都有(you)(you)(you)(you)著很(hen)大的(de)(de)(de)(de)(de)(de)威(wei)脅。可以說(shuo)有(you)(you)(you)(you)了電(dian)(dian)(dian)(dian)源(yuan)適配器(qi)(qi)就(jiu)相當于給我(wo)們(men)(men)的(de)(de)(de)(de)(de)(de)家(jia)用(yong)(yong)電(dian)(dian)(dian)(dian)器(qi)(qi)上(shang)了保(bao)險。再(zai)也(ye)不(bu)用(yong)(yong)擔心那(nei)些意外事故了。
