電源適配器行業簡介

一、電源適配器是什么

電(dian)(dian)(dian)源(yuan)(yuan)適(shi)配器(qi)又稱外(wai)置電(dian)(dian)(dian)源(yuan)(yuan)，是(shi)一種小(xiao)型(xing)便攜式(shi)電(dian)(dian)(dian)子設(she)備及(ji)電(dian)(dian)(dian)子電(dian)(dian)(dian)器(qi)的(de)供(gong)(gong)電(dian)(dian)(dian)電(dian)(dian)(dian)壓變(bian)換設(she)備，由外(wai)殼(ke)、變(bian)壓器(qi)、電(dian)(dian)(dian)感、電(dian)(dian)(dian)容(rong)、控(kong)制IC、PCB板等(deng)元(yuan)器(qi)件(jian)組成，它的(de)作(zuo)用主要是(shi)：將電(dian)(dian)(dian)流(liu)由交流(liu)輸(shu)入轉(zhuan)換為(wei)直(zhi)流(liu)輸(shu)出，把不穩(wen)定(ding)的(de)電(dian)(dian)(dian)源(yuan)(yuan)通過轉(zhuan)化電(dian)(dian)(dian)路變(bian)成電(dian)(dian)(dian)子產品(pin)需要的(de)恒壓直(zhi)流(liu)電(dian)(dian)(dian)，從(cong)而給物(wu)體供(gong)(gong)電(dian)(dian)(dian)和充電(dian)(dian)(dian)。電(dian)(dian)(dian)源(yuan)(yuan)適(shi)配器(qi)可以看作(zuo)是(shi)變(bian)壓器(qi)和整(zheng)流(liu)器(qi)，可以起(qi)到保護電(dian)(dian)(dian)器(qi)和人身安全的(de)作(zuo)用。

二、電源適配器是充電器嗎

電(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)適配(pei)(pei)器(qi)(qi)(qi)并不是充電(dian)(dian)(dian)器(qi)(qi)(qi)，電(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)適配(pei)(pei)器(qi)(qi)(qi)是電(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)開關，用(yong)于提供(gong)(gong)電(dian)(dian)(dian)力能(neng)源(yuan)(yuan)(yuan)(yuan)，可以給投(tou)影儀、筆記本(ben)電(dian)(dian)(dian)腦、音響、凈水(shui)器(qi)(qi)(qi)等家用(yong)電(dian)(dian)(dian)器(qi)(qi)(qi)或電(dian)(dian)(dian)子產品(pin)提供(gong)(gong)電(dian)(dian)(dian)力；而充電(dian)(dian)(dian)器(qi)(qi)(qi)是用(yong)來給電(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)的，一般會根據電(dian)(dian)(dian)池(chi)容量和(he)充電(dian)(dian)(dian)特(te)性(xing)進(jin)行(xing)分階段充電(dian)(dian)(dian)，二者是不同的。電(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)適配(pei)(pei)器(qi)(qi)(qi)和(he)電(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)充電(dian)(dian)(dian)器(qi)(qi)(qi)的區別(bie)還(huan)體現在定義、結構、電(dian)(dian)(dian)流模式、用(yong)途(tu)等方面，最大的區別(bie)就是充電(dian)(dian)(dian)器(qi)(qi)(qi)只是給電(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)，而電(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)適配(pei)(pei)器(qi)(qi)(qi)不僅能(neng)給電(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)，還(huan)能(neng)給主機供(gong)(gong)電(dian)(dian)(dian)。

三、電源適配器可以通用嗎

一(yi)(yi)般情況(kuang)下，電(dian)源適(shi)配器(qi)(qi)能(neng)否通(tong)用(yong)要滿足三個條件：輸出(chu)電(dian)壓必須相(xiang)同(tong)、輸出(chu)的(de)(de)額定(ding)電(dian)流比原電(dian)器(qi)(qi)要求的(de)(de)要大、接口(kou)相(xiang)同(tong)，如果這(zhe)三個方(fang)面都滿足的(de)(de)話(hua)，可(ke)以臨時通(tong)用(yong)一(yi)(yi)下。不過(guo)需要注意的(de)(de)是，部分電(dian)源適(shi)配器(qi)(qi)也是不可(ke)以通(tong)用(yong)的(de)(de)，通(tong)用(yong)可(ke)能(neng)會導致電(dian)器(qi)(qi)燒壞(huai)、無法使用(yong)等問題，因此如果原來的(de)(de)電(dian)源適(shi)配器(qi)(qi)損壞(huai)，建議還是聯(lian)系廠家購買一(yi)(yi)個原裝電(dian)源適(shi)配器(qi)(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。
