電源適配器行業簡介

一、電源適配器是什么

電(dian)(dian)(dian)(dian)(dian)源適(shi)配器又(you)稱外置電(dian)(dian)(dian)(dian)(dian)源，是一(yi)種(zhong)小型便攜式(shi)電(dian)(dian)(dian)(dian)(dian)子(zi)設備(bei)及電(dian)(dian)(dian)(dian)(dian)子(zi)電(dian)(dian)(dian)(dian)(dian)器的(de)(de)供電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓(ya)變(bian)(bian)換(huan)設備(bei)，由外殼(ke)、變(bian)(bian)壓(ya)器、電(dian)(dian)(dian)(dian)(dian)感、電(dian)(dian)(dian)(dian)(dian)容(rong)、控(kong)制IC、PCB板等元器件(jian)組成，它的(de)(de)作用主(zhu)要(yao)(yao)是：將電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)由交流(liu)(liu)輸(shu)入轉換(huan)為直(zhi)(zhi)流(liu)(liu)輸(shu)出，把不穩定的(de)(de)電(dian)(dian)(dian)(dian)(dian)源通過轉化電(dian)(dian)(dian)(dian)(dian)路變(bian)(bian)成電(dian)(dian)(dian)(dian)(dian)子(zi)產(chan)品需要(yao)(yao)的(de)(de)恒壓(ya)直(zhi)(zhi)流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)，從(cong)而給物(wu)體供電(dian)(dian)(dian)(dian)(dian)和(he)(he)充電(dian)(dian)(dian)(dian)(dian)。電(dian)(dian)(dian)(dian)(dian)源適(shi)配器可以看作是變(bian)(bian)壓(ya)器和(he)(he)整(zheng)流(liu)(liu)器，可以起到保護電(dian)(dian)(dian)(dian)(dian)器和(he)(he)人身安(an)全的(de)(de)作用。

二、電源適配器是充電器嗎

電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)適配(pei)器(qi)(qi)(qi)并不是(shi)(shi)(shi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)，電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)適配(pei)器(qi)(qi)(qi)是(shi)(shi)(shi)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)開關(guan)，用于提供電(dian)(dian)(dian)(dian)(dian)力能(neng)源(yuan)(yuan)(yuan)，可以給投(tou)影儀、筆記本(ben)電(dian)(dian)(dian)(dian)(dian)腦、音(yin)響、凈(jing)水器(qi)(qi)(qi)等(deng)家用電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)或電(dian)(dian)(dian)(dian)(dian)子(zi)產品提供電(dian)(dian)(dian)(dian)(dian)力；而(er)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)是(shi)(shi)(shi)用來給電(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)的，一(yi)般會(hui)根據電(dian)(dian)(dian)(dian)(dian)池容量和(he)(he)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)特(te)性進(jin)行分(fen)階(jie)段(duan)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，二(er)者是(shi)(shi)(shi)不同的。電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)適配(pei)器(qi)(qi)(qi)和(he)(he)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)的區別(bie)還體現在定(ding)義、結構、電(dian)(dian)(dian)(dian)(dian)流模式、用途等(deng)方面，最大的區別(bie)就(jiu)是(shi)(shi)(shi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)只是(shi)(shi)(shi)給電(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，而(er)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)適配(pei)器(qi)(qi)(qi)不僅(jin)能(neng)給電(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，還能(neng)給主機供電(dian)(dian)(dian)(dian)(dian)。

三、電源適配器可以通用嗎

一般情況下，電源(yuan)適配器能否通用(yong)要滿(man)足三個條件：輸出電壓必須(xu)相同、輸出的(de)額定(ding)電流比原(yuan)電器要求的(de)要大、接口相同，如果(guo)這三個方面都(dou)滿(man)足的(de)話，可(ke)(ke)以臨時(shi)通用(yong)一下。不(bu)過(guo)需要注意的(de)是，部分電源(yuan)適配器也是不(bu)可(ke)(ke)以通用(yong)的(de)，通用(yong)可(ke)(ke)能會導(dao)致電器燒壞、無法使用(yong)等問題(ti)，因此(ci)如果(guo)原(yuan)來(lai)的(de)電源(yuan)適配器損壞，建議還是聯系(xi)廠(chang)家購買一個原(yuan)裝(zhuang)電源(yuan)適配器比較好。

四、電源適配器多少錢一個

電源適配器的價格并不高，根據輸入電壓大小、輸入電流類型、供電方式、電源安數等有所不同，價格大概在二十多元到四五十元左右，也有部分電源適配器產品可能會更貴一些。需要注意的是，電源適配器市場比較混亂，有一些比較便宜的電源適配器甚至只要幾塊錢，這種可能是以次充好、以舊充新的產品，不建議購買，要選擇正規優質的電源適配器品牌廠家購買產品。
