電源適配器行業簡介

一、電源適配器是什么

電(dian)(dian)(dian)源適配(pei)器(qi)(qi)又稱外置電(dian)(dian)(dian)源，是(shi)一種(zhong)小型便攜式(shi)電(dian)(dian)(dian)子(zi)設(she)備及電(dian)(dian)(dian)子(zi)電(dian)(dian)(dian)器(qi)(qi)的(de)供電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)(ya)變(bian)換(huan)設(she)備，由(you)外殼、變(bian)壓(ya)(ya)器(qi)(qi)、電(dian)(dian)(dian)感、電(dian)(dian)(dian)容(rong)、控制IC、PCB板等(deng)元器(qi)(qi)件組成，它的(de)作(zuo)(zuo)用(yong)(yong)主要(yao)是(shi)：將電(dian)(dian)(dian)流(liu)由(you)交流(liu)輸(shu)入轉換(huan)為直流(liu)輸(shu)出，把不穩定的(de)電(dian)(dian)(dian)源通(tong)過轉化電(dian)(dian)(dian)路(lu)變(bian)成電(dian)(dian)(dian)子(zi)產品需要(yao)的(de)恒壓(ya)(ya)直流(liu)電(dian)(dian)(dian)，從而(er)給(gei)物體(ti)供電(dian)(dian)(dian)和充電(dian)(dian)(dian)。電(dian)(dian)(dian)源適配(pei)器(qi)(qi)可以看作(zuo)(zuo)是(shi)變(bian)壓(ya)(ya)器(qi)(qi)和整流(liu)器(qi)(qi)，可以起到保護(hu)電(dian)(dian)(dian)器(qi)(qi)和人身安全的(de)作(zuo)(zuo)用(yong)(yong)。

二、電源適配器是充電器嗎

電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適配器(qi)(qi)并不(bu)是(shi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)，電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適配器(qi)(qi)是(shi)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)開關，用(yong)于提(ti)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)力能(neng)源(yuan)，可以(yi)給投影(ying)儀(yi)、筆記本電(dian)(dian)(dian)(dian)(dian)(dian)腦、音響、凈水器(qi)(qi)等家用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)或電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)產品提(ti)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)力；而(er)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)是(shi)用(yong)來給電(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)的，一(yi)般會(hui)根據電(dian)(dian)(dian)(dian)(dian)(dian)池容(rong)量(liang)和充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)特性進行分階(jie)段充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，二(er)者是(shi)不(bu)同的。電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適配器(qi)(qi)和電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)的區別還(huan)體現在定義(yi)、結(jie)構(gou)、電(dian)(dian)(dian)(dian)(dian)(dian)流模式(shi)、用(yong)途等方(fang)面，最大的區別就是(shi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)只是(shi)給電(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，而(er)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適配器(qi)(qi)不(bu)僅(jin)能(neng)給電(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，還(huan)能(neng)給主機供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)。

三、電源適配器可以通用嗎

一(yi)(yi)般情況下，電(dian)(dian)源(yuan)適配(pei)(pei)器能(neng)否通用(yong)要(yao)滿(man)足(zu)三個條件：輸(shu)出電(dian)(dian)壓必須(xu)相(xiang)同、輸(shu)出的(de)(de)(de)額定電(dian)(dian)流比原(yuan)電(dian)(dian)器要(yao)求(qiu)的(de)(de)(de)要(yao)大、接(jie)口相(xiang)同，如果這三個方(fang)面都滿(man)足(zu)的(de)(de)(de)話(hua)，可(ke)以臨時通用(yong)一(yi)(yi)下。不過需(xu)要(yao)注意的(de)(de)(de)是(shi)，部分電(dian)(dian)源(yuan)適配(pei)(pei)器也是(shi)不可(ke)以通用(yong)的(de)(de)(de)，通用(yong)可(ke)能(neng)會(hui)導致電(dian)(dian)器燒(shao)壞、無(wu)法使用(yong)等問題，因此(ci)如果原(yuan)來(lai)的(de)(de)(de)電(dian)(dian)源(yuan)適配(pei)(pei)器損壞，建議(yi)還是(shi)聯系廠家(jia)購買(mai)一(yi)(yi)個原(yuan)裝電(dian)(dian)源(yuan)適配(pei)(pei)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。
