電源適配器行業簡介

一、電源適配器是什么

電(dian)(dian)(dian)源(yuan)適配器(qi)又稱外(wai)置(zhi)電(dian)(dian)(dian)源(yuan)，是一種小型便攜式電(dian)(dian)(dian)子(zi)(zi)設備及電(dian)(dian)(dian)子(zi)(zi)電(dian)(dian)(dian)器(qi)的供(gong)電(dian)(dian)(dian)電(dian)(dian)(dian)壓變(bian)換設備，由(you)外(wai)殼、變(bian)壓器(qi)、電(dian)(dian)(dian)感(gan)、電(dian)(dian)(dian)容、控(kong)制IC、PCB板(ban)等元器(qi)件組成，它的作(zuo)(zuo)用(yong)主要是：將(jiang)電(dian)(dian)(dian)流由(you)交流輸(shu)入轉換為直流輸(shu)出，把不穩定(ding)的電(dian)(dian)(dian)源(yuan)通過轉化電(dian)(dian)(dian)路(lu)變(bian)成電(dian)(dian)(dian)子(zi)(zi)產品需(xu)要的恒(heng)壓直流電(dian)(dian)(dian)，從而給物體供(gong)電(dian)(dian)(dian)和充電(dian)(dian)(dian)。電(dian)(dian)(dian)源(yuan)適配器(qi)可以(yi)看作(zuo)(zuo)是變(bian)壓器(qi)和整流器(qi)，可以(yi)起到(dao)保護電(dian)(dian)(dian)器(qi)和人身安全的作(zuo)(zuo)用(yong)。

二、電源適配器是充電器嗎

電(dian)(dian)(dian)(dian)源(yuan)(yuan)適(shi)(shi)配器并不是充(chong)電(dian)(dian)(dian)(dian)器，電(dian)(dian)(dian)(dian)源(yuan)(yuan)適(shi)(shi)配器是電(dian)(dian)(dian)(dian)源(yuan)(yuan)開關，用(yong)于提(ti)(ti)供(gong)電(dian)(dian)(dian)(dian)力能源(yuan)(yuan)，可以給(gei)(gei)投影儀、筆記本電(dian)(dian)(dian)(dian)腦、音響、凈水(shui)器等家用(yong)電(dian)(dian)(dian)(dian)器或電(dian)(dian)(dian)(dian)子(zi)產品提(ti)(ti)供(gong)電(dian)(dian)(dian)(dian)力；而充(chong)電(dian)(dian)(dian)(dian)器是用(yong)來給(gei)(gei)電(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)的，一(yi)般會根據電(dian)(dian)(dian)(dian)池容量和充(chong)電(dian)(dian)(dian)(dian)特性進行分階(jie)段充(chong)電(dian)(dian)(dian)(dian)，二者是不同(tong)的。電(dian)(dian)(dian)(dian)源(yuan)(yuan)適(shi)(shi)配器和電(dian)(dian)(dian)(dian)源(yuan)(yuan)充(chong)電(dian)(dian)(dian)(dian)器的區別還體現在定(ding)義、結構、電(dian)(dian)(dian)(dian)流(liu)模式、用(yong)途等方面(mian)，最大的區別就是充(chong)電(dian)(dian)(dian)(dian)器只(zhi)是給(gei)(gei)電(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)，而電(dian)(dian)(dian)(dian)源(yuan)(yuan)適(shi)(shi)配器不僅能給(gei)(gei)電(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)，還能給(gei)(gei)主機供(gong)電(dian)(dian)(dian)(dian)。

三、電源適配器可以通用嗎

一般情況下，電(dian)(dian)(dian)源適(shi)配(pei)器能否通(tong)用(yong)(yong)要(yao)滿足三(san)個(ge)條(tiao)件：輸出電(dian)(dian)(dian)壓(ya)必須(xu)相(xiang)同(tong)、輸出的額定電(dian)(dian)(dian)流比原電(dian)(dian)(dian)器要(yao)求的要(yao)大、接口相(xiang)同(tong)，如果這(zhe)三(san)個(ge)方(fang)面都滿足的話(hua)，可以(yi)臨時(shi)通(tong)用(yong)(yong)一下。不過(guo)需要(yao)注(zhu)意的是(shi)，部分電(dian)(dian)(dian)源適(shi)配(pei)器也是(shi)不可以(yi)通(tong)用(yong)(yong)的，通(tong)用(yong)(yong)可能會導(dao)致電(dian)(dian)(dian)器燒壞(huai)、無法使用(yong)(yong)等問題，因此(ci)如果原來(lai)的電(dian)(dian)(dian)源適(shi)配(pei)器損壞(huai)，建議還是(shi)聯系廠家購買一個(ge)原裝電(dian)(dian)(dian)源適(shi)配(pei)器比較好。

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。
