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(cheng)外置電(dian)(dian)(dian)源，是一(yi)種小型便攜式電(dian)(dian)(dian)子設(she)備及電(dian)(dian)(dian)子電(dian)(dian)(dian)器(qi)(qi)的(de)(de)供(gong)電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)(ya)變換設(she)備，由外殼、變壓(ya)(ya)器(qi)(qi)、電(dian)(dian)(dian)感、電(dian)(dian)(dian)容、控制IC、PCB板等元器(qi)(qi)件(jian)組(zu)成，它的(de)(de)作(zuo)用(yong)主(zhu)要(yao)是：將(jiang)電(dian)(dian)(dian)流由交(jiao)流輸入轉(zhuan)換為(wei)直流輸出，把不穩定的(de)(de)電(dian)(dian)(dian)源通(tong)過(guo)轉(zhuan)化電(dian)(dian)(dian)路(lu)變成電(dian)(dian)(dian)子產品(pin)需要(yao)的(de)(de)恒壓(ya)(ya)直流電(dian)(dian)(dian)，從而給(gei)物體供(gong)電(dian)(dian)(dian)和(he)充電(dian)(dian)(dian)。電(dian)(dian)(dian)源適配(pei)器(qi)(qi)可以(yi)看作(zuo)是變壓(ya)(ya)器(qi)(qi)和(he)整流器(qi)(qi)，可以(yi)起到(dao)保護(hu)電(dian)(dian)(dian)器(qi)(qi)和(he)人身安全的(de)(de)作(zuo)用(yong)。

二、電源適配器是充電器嗎

電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)適(shi)(shi)(shi)配(pei)器(qi)(qi)并不(bu)是(shi)(shi)(shi)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)適(shi)(shi)(shi)配(pei)器(qi)(qi)是(shi)(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)開關，用于(yu)提供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力能(neng)源(yuan)(yuan)，可以給投影儀、筆記本電(dian)(dian)(dian)(dian)(dian)(dian)(dian)腦、音(yin)響、凈水(shui)器(qi)(qi)等家(jia)用電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)或電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子產品提供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力；而充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)是(shi)(shi)(shi)用來給電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的，一般(ban)會根據電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)容量和(he)(he)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)特性進行(xing)分階(jie)段(duan)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，二者是(shi)(shi)(shi)不(bu)同的。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)適(shi)(shi)(shi)配(pei)器(qi)(qi)和(he)(he)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)的區別還(huan)體現在(zai)定義(yi)、結構、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流模(mo)式、用途等方面，最大(da)的區別就(jiu)是(shi)(shi)(shi)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)只是(shi)(shi)(shi)給電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，而電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)適(shi)(shi)(shi)配(pei)器(qi)(qi)不(bu)僅(jin)能(neng)給電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，還(huan)能(neng)給主機供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。

三、電源適配器可以通用嗎

一般(ban)情況下，電(dian)源(yuan)(yuan)適(shi)配(pei)器(qi)(qi)能否通用(yong)(yong)要(yao)滿足三(san)個(ge)條件：輸出(chu)電(dian)壓必須相同、輸出(chu)的(de)(de)額定電(dian)流比原(yuan)電(dian)器(qi)(qi)要(yao)求的(de)(de)要(yao)大、接口(kou)相同，如(ru)果(guo)這(zhe)三(san)個(ge)方面都滿足的(de)(de)話(hua)，可以臨時通用(yong)(yong)一下。不過(guo)需要(yao)注意的(de)(de)是(shi)，部分電(dian)源(yuan)(yuan)適(shi)配(pei)器(qi)(qi)也是(shi)不可以通用(yong)(yong)的(de)(de)，通用(yong)(yong)可能會導致電(dian)器(qi)(qi)燒壞、無法使(shi)用(yong)(yong)等問題，因(yin)此如(ru)果(guo)原(yuan)來的(de)(de)電(dian)源(yuan)(yuan)適(shi)配(pei)器(qi)(qi)損壞，建議還是(shi)聯系廠家購買一個(ge)原(yuan)裝電(dian)源(yuan)(yuan)適(shi)配(pei)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。
