電源適配器行業簡介

一、電源適配器是什么

電(dian)源適(shi)配器(qi)(qi)又稱外置電(dian)源，是(shi)一種小型便攜式電(dian)子設備及電(dian)子電(dian)器(qi)(qi)的供電(dian)電(dian)壓(ya)變(bian)(bian)換(huan)設備，由(you)外殼、變(bian)(bian)壓(ya)器(qi)(qi)、電(dian)感(gan)、電(dian)容、控制(zhi)IC、PCB板等元(yuan)器(qi)(qi)件組成，它的作(zuo)用(yong)(yong)主要是(shi)：將電(dian)流(liu)由(you)交流(liu)輸(shu)入轉換(huan)為直流(liu)輸(shu)出，把(ba)不穩定的電(dian)源通過轉化電(dian)路(lu)變(bian)(bian)成電(dian)子產品需要的恒壓(ya)直流(liu)電(dian)，從(cong)而(er)給物體(ti)供電(dian)和充電(dian)。電(dian)源適(shi)配器(qi)(qi)可以看(kan)作(zuo)是(shi)變(bian)(bian)壓(ya)器(qi)(qi)和整(zheng)流(liu)器(qi)(qi)，可以起(qi)到保(bao)護電(dian)器(qi)(qi)和人(ren)身安全的作(zuo)用(yong)(yong)。

二、電源適配器是充電器嗎

電(dian)(dian)(dian)(dian)源(yuan)適(shi)配器(qi)(qi)并(bing)不(bu)是(shi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)，電(dian)(dian)(dian)(dian)源(yuan)適(shi)配器(qi)(qi)是(shi)電(dian)(dian)(dian)(dian)源(yuan)開關，用(yong)于提(ti)供(gong)電(dian)(dian)(dian)(dian)力能源(yuan)，可以給投(tou)影(ying)儀(yi)、筆記本電(dian)(dian)(dian)(dian)腦、音響、凈水器(qi)(qi)等家用(yong)電(dian)(dian)(dian)(dian)器(qi)(qi)或電(dian)(dian)(dian)(dian)子產(chan)品提(ti)供(gong)電(dian)(dian)(dian)(dian)力；而(er)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)是(shi)用(yong)來給電(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)的(de)，一般(ban)會根據(ju)電(dian)(dian)(dian)(dian)池容(rong)量和(he)(he)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)特性進行(xing)分階段充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)，二者(zhe)是(shi)不(bu)同(tong)的(de)。電(dian)(dian)(dian)(dian)源(yuan)適(shi)配器(qi)(qi)和(he)(he)電(dian)(dian)(dian)(dian)源(yuan)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)的(de)區別(bie)還體(ti)現在定義、結構、電(dian)(dian)(dian)(dian)流模式、用(yong)途等方面，最大的(de)區別(bie)就是(shi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)(qi)只是(shi)給電(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)，而(er)電(dian)(dian)(dian)(dian)源(yuan)適(shi)配器(qi)(qi)不(bu)僅能給電(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)，還能給主機供(gong)電(dian)(dian)(dian)(dian)。

三、電源適配器可以通用嗎

一般情況下，電(dian)(dian)源適(shi)配(pei)器(qi)能否通(tong)用要滿足三個(ge)條件：輸出(chu)電(dian)(dian)壓必須相(xiang)同(tong)、輸出(chu)的(de)額定電(dian)(dian)流(liu)比原電(dian)(dian)器(qi)要求的(de)要大(da)、接口相(xiang)同(tong)，如果這(zhe)三個(ge)方(fang)面都滿足的(de)話(hua)，可(ke)以臨時通(tong)用一下。不過(guo)需要注(zhu)意的(de)是(shi)，部分電(dian)(dian)源適(shi)配(pei)器(qi)也(ye)是(shi)不可(ke)以通(tong)用的(de)，通(tong)用可(ke)能會(hui)導(dao)致電(dian)(dian)器(qi)燒壞(huai)、無法使用等(deng)問題(ti)，因此如果原來的(de)電(dian)(dian)源適(shi)配(pei)器(qi)損壞(huai)，建議(yi)還是(shi)聯系(xi)廠家購買一個(ge)原裝電(dian)(dian)源適(shi)配(pei)器(qi)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。
