電源適配器行業簡介

一、電源適配器是什么

電(dian)(dian)(dian)源(yuan)適配(pei)器(qi)又稱外置(zhi)電(dian)(dian)(dian)源(yuan)，是(shi)一種小(xiao)型便(bian)攜式電(dian)(dian)(dian)子(zi)設(she)備及(ji)電(dian)(dian)(dian)子(zi)電(dian)(dian)(dian)器(qi)的(de)供電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)變(bian)換設(she)備，由外殼、變(bian)壓(ya)器(qi)、電(dian)(dian)(dian)感、電(dian)(dian)(dian)容(rong)、控制IC、PCB板等元器(qi)件組(zu)成，它的(de)作(zuo)(zuo)用主要是(shi)：將(jiang)電(dian)(dian)(dian)流由交流輸入(ru)轉換為(wei)直流輸出(chu)，把不穩(wen)定的(de)電(dian)(dian)(dian)源(yuan)通過轉化電(dian)(dian)(dian)路變(bian)成電(dian)(dian)(dian)子(zi)產品需要的(de)恒(heng)壓(ya)直流電(dian)(dian)(dian)，從(cong)而給物(wu)體供電(dian)(dian)(dian)和(he)充電(dian)(dian)(dian)。電(dian)(dian)(dian)源(yuan)適配(pei)器(qi)可以看作(zuo)(zuo)是(shi)變(bian)壓(ya)器(qi)和(he)整流器(qi)，可以起到保護電(dian)(dian)(dian)器(qi)和(he)人身安全的(de)作(zuo)(zuo)用。

二、電源適配器是充電器嗎

電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)配(pei)器(qi)(qi)(qi)并不(bu)(bu)是充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)配(pei)器(qi)(qi)(qi)是電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)開關，用于提供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)力能(neng)源(yuan)，可以給(gei)投影儀、筆記本(ben)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)腦、音響(xiang)、凈水器(qi)(qi)(qi)等家用電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)或電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子產品提供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)力；而充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)是用來給(gei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)，一般會根據電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)容(rong)量和(he)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)特性進(jin)行(xing)分(fen)階段(duan)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，二者是不(bu)(bu)同(tong)的(de)。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)配(pei)器(qi)(qi)(qi)和(he)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)的(de)區別還體現在定(ding)義(yi)、結構、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流模式、用途(tu)等方面(mian)，最大的(de)區別就是充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)只是給(gei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，而電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)配(pei)器(qi)(qi)(qi)不(bu)(bu)僅(jin)能(neng)給(gei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，還能(neng)給(gei)主機供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)。

三、電源適配器可以通用嗎

一般情況(kuang)下，電源(yuan)適(shi)(shi)配器能(neng)否通(tong)用(yong)要滿足(zu)三個條(tiao)件：輸出電壓必須相同(tong)、輸出的(de)(de)(de)額定電流比(bi)原(yuan)電器要求的(de)(de)(de)要大、接(jie)口(kou)相同(tong)，如果這(zhe)三個方(fang)面都滿足(zu)的(de)(de)(de)話，可以臨時通(tong)用(yong)一下。不(bu)過需(xu)要注意的(de)(de)(de)是，部分電源(yuan)適(shi)(shi)配器也是不(bu)可以通(tong)用(yong)的(de)(de)(de)，通(tong)用(yong)可能(neng)會導致電器燒壞、無法使用(yong)等問題，因此(ci)如果原(yuan)來的(de)(de)(de)電源(yuan)適(shi)(shi)配器損壞，建議還是聯系廠家購買一個原(yuan)裝電源(yuan)適(shi)(shi)配器比(bi)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。
