電源適配器行業簡介

一、電源適配器是什么

電(dian)(dian)(dian)(dian)源適配器(qi)又稱外置電(dian)(dian)(dian)(dian)源，是一種(zhong)小型便(bian)攜式(shi)電(dian)(dian)(dian)(dian)子(zi)設備及(ji)電(dian)(dian)(dian)(dian)子(zi)電(dian)(dian)(dian)(dian)器(qi)的(de)(de)供(gong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓(ya)(ya)變(bian)(bian)換設備，由(you)外殼、變(bian)(bian)壓(ya)(ya)器(qi)、電(dian)(dian)(dian)(dian)感、電(dian)(dian)(dian)(dian)容、控制IC、PCB板等元器(qi)件組(zu)成(cheng)，它的(de)(de)作用主(zhu)要是：將(jiang)電(dian)(dian)(dian)(dian)流(liu)由(you)交流(liu)輸入轉(zhuan)換為直流(liu)輸出，把不穩定的(de)(de)電(dian)(dian)(dian)(dian)源通過轉(zhuan)化(hua)電(dian)(dian)(dian)(dian)路變(bian)(bian)成(cheng)電(dian)(dian)(dian)(dian)子(zi)產品需要的(de)(de)恒壓(ya)(ya)直流(liu)電(dian)(dian)(dian)(dian)，從而(er)給物體(ti)供(gong)電(dian)(dian)(dian)(dian)和充電(dian)(dian)(dian)(dian)。電(dian)(dian)(dian)(dian)源適配器(qi)可(ke)以(yi)看作是變(bian)(bian)壓(ya)(ya)器(qi)和整流(liu)器(qi)，可(ke)以(yi)起到保護電(dian)(dian)(dian)(dian)器(qi)和人身安全的(de)(de)作用。

二、電源適配器是充電器嗎

電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)適(shi)(shi)配器(qi)并不(bu)是充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)適(shi)(shi)配器(qi)是電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)開關，用(yong)于提供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)力能源(yuan)(yuan)(yuan)，可以(yi)給(gei)投影儀、筆(bi)記本電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)腦、音響、凈水器(qi)等(deng)家用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)或(huo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子產品提供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)力；而(er)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)是用(yong)來(lai)給(gei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)，一般會根據電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)容(rong)量和充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)特(te)性進行分(fen)階段充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，二者(zhe)是不(bu)同的(de)。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)適(shi)(shi)配器(qi)和電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)的(de)區(qu)別還體現(xian)在定義、結構、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流模式、用(yong)途等(deng)方面，最大的(de)區(qu)別就是充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)只(zhi)是給(gei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，而(er)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)適(shi)(shi)配器(qi)不(bu)僅能給(gei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，還能給(gei)主機供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)。

三、電源適配器可以通用嗎

一般情況下，電(dian)(dian)源適配(pei)器(qi)能否通(tong)用(yong)要滿足三個(ge)條(tiao)件：輸出電(dian)(dian)壓(ya)必須相(xiang)(xiang)同、輸出的額定電(dian)(dian)流比原(yuan)電(dian)(dian)器(qi)要求的要大、接(jie)口相(xiang)(xiang)同，如果這三個(ge)方面都(dou)滿足的話，可(ke)(ke)(ke)以臨時通(tong)用(yong)一下。不(bu)過需要注意的是(shi)，部分電(dian)(dian)源適配(pei)器(qi)也是(shi)不(bu)可(ke)(ke)(ke)以通(tong)用(yong)的，通(tong)用(yong)可(ke)(ke)(ke)能會導致電(dian)(dian)器(qi)燒壞、無法使(shi)用(yong)等問題(ti)，因此如果原(yuan)來的電(dian)(dian)源適配(pei)器(qi)損壞，建議還是(shi)聯系廠家購買一個(ge)原(yuan)裝電(dian)(dian)源適配(pei)器(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。
