電源適配器行業簡介

一、電源適配器是什么

電(dian)源(yuan)適配器(qi)(qi)(qi)又稱外置電(dian)源(yuan)，是(shi)(shi)一種小(xiao)型(xing)便攜(xie)式電(dian)子(zi)設備(bei)及電(dian)子(zi)電(dian)器(qi)(qi)(qi)的(de)供(gong)電(dian)電(dian)壓變(bian)(bian)(bian)換設備(bei)，由(you)外殼、變(bian)(bian)(bian)壓器(qi)(qi)(qi)、電(dian)感、電(dian)容、控制(zhi)IC、PCB板等元器(qi)(qi)(qi)件組成，它的(de)作用主要(yao)是(shi)(shi)：將電(dian)流(liu)由(you)交流(liu)輸入(ru)轉(zhuan)換為直(zhi)流(liu)輸出，把不穩定(ding)的(de)電(dian)源(yuan)通過轉(zhuan)化電(dian)路變(bian)(bian)(bian)成電(dian)子(zi)產品需要(yao)的(de)恒壓直(zhi)流(liu)電(dian)，從(cong)而給物(wu)體供(gong)電(dian)和充電(dian)。電(dian)源(yuan)適配器(qi)(qi)(qi)可(ke)以看作是(shi)(shi)變(bian)(bian)(bian)壓器(qi)(qi)(qi)和整(zheng)流(liu)器(qi)(qi)(qi)，可(ke)以起到保(bao)護電(dian)器(qi)(qi)(qi)和人身安全的(de)作用。

二、電源適配器是充電器嗎

電(dian)(dian)(dian)(dian)源(yuan)(yuan)適配(pei)器(qi)并(bing)不是(shi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)，電(dian)(dian)(dian)(dian)源(yuan)(yuan)適配(pei)器(qi)是(shi)電(dian)(dian)(dian)(dian)源(yuan)(yuan)開關，用(yong)于提供(gong)電(dian)(dian)(dian)(dian)力能(neng)源(yuan)(yuan)，可以給(gei)投影儀、筆(bi)記本(ben)電(dian)(dian)(dian)(dian)腦(nao)、音響、凈水器(qi)等家用(yong)電(dian)(dian)(dian)(dian)器(qi)或電(dian)(dian)(dian)(dian)子(zi)產品(pin)提供(gong)電(dian)(dian)(dian)(dian)力；而充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)是(shi)用(yong)來給(gei)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)的，一般(ban)會根據電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)容量(liang)和充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)特性進行分階段(duan)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)，二(er)者是(shi)不同的。電(dian)(dian)(dian)(dian)源(yuan)(yuan)適配(pei)器(qi)和電(dian)(dian)(dian)(dian)源(yuan)(yuan)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)的區(qu)別還體現在定義、結構、電(dian)(dian)(dian)(dian)流(liu)模式、用(yong)途等方(fang)面(mian)，最大的區(qu)別就是(shi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)器(qi)只是(shi)給(gei)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)，而電(dian)(dian)(dian)(dian)源(yuan)(yuan)適配(pei)器(qi)不僅(jin)能(neng)給(gei)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)，還能(neng)給(gei)主機(ji)供(gong)電(dian)(dian)(dian)(dian)。

三、電源適配器可以通用嗎

一(yi)般(ban)情況下，電(dian)源適(shi)配器(qi)(qi)(qi)能否通(tong)用要滿足三(san)個(ge)條件(jian)：輸(shu)出電(dian)壓必須相(xiang)同、輸(shu)出的(de)(de)額定電(dian)流比原(yuan)(yuan)電(dian)器(qi)(qi)(qi)要求的(de)(de)要大、接口(kou)相(xiang)同，如果(guo)這三(san)個(ge)方面(mian)都滿足的(de)(de)話，可以(yi)臨(lin)時通(tong)用一(yi)下。不(bu)過需要注(zhu)意的(de)(de)是(shi)，部分電(dian)源適(shi)配器(qi)(qi)(qi)也是(shi)不(bu)可以(yi)通(tong)用的(de)(de)，通(tong)用可能會(hui)導致電(dian)器(qi)(qi)(qi)燒壞、無(wu)法使用等問題，因此如果(guo)原(yuan)(yuan)來的(de)(de)電(dian)源適(shi)配器(qi)(qi)(qi)損壞，建議還(huan)是(shi)聯系(xi)廠(chang)家購買一(yi)個(ge)原(yuan)(yuan)裝電(dian)源適(shi)配器(qi)(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。
