在如今，儀表儀器機器設備在特性上更為可以信賴，作用上不斷提高，應用上自動化技術水平也愈來愈高。而這種電子信息技術以及運用飛速發展都不可或缺電源適配器，電源適配器在電子計算機、通訊、航空航天、家用電器等層面都獲得了愈來愈普遍的運用，電源適配器的種(zhong)類也愈來愈多(duo)。電源適配器常(chang)有什么分類?

　　1、按調配方法分類

　　①脈(mo)(mo)沖寬度調制(zhi)(zhi)型開關(guan)穩壓(ya)電(dian)(dian)源適配器。震(zhen)蕩頻率保持一致，根(gen)(gen)據(ju)(ju)更改(gai)單脈(mo)(mo)沖總寬來更改(gai)和調整輸(shu)出(chu)工作(zuo)電(dian)(dian)壓(ya)的(de)尺寸，有時(shi)候根(gen)(gen)據(ju)(ju)抽樣(yang)電(dian)(dian)路(lu)、藕合電(dian)(dian)路(lu)等(deng)組成意見反饋閉環控(kong)(kong)制(zhi)(zhi)控(kong)(kong)制(zhi)(zhi)回路(lu)來平穩輸(shu)出(chu)工作(zuo)電(dian)(dian)壓(ya)的(de)力度。

　　②頻(pin)率調配型開關穩壓電源(yuan)適配器。占空比(bi)保持一致(zhi)，根(gen)據更(geng)改震蕩(dang)器的(de)震蕩(dang)頻(pin)率來調整和平穩輸出工(gong)作電壓的(de)力度。

　　③混和調配型開關穩壓電(dian)源適配器。根據調整(zheng)(zheng)通斷(duan)時間的(de)震蕩(dang)頻率來進行調整(zheng)(zheng)和平穩輸出工作電(dian)壓的(de)力(li)度。

　　2、按電路構造分類

　　①單件式開(kai)關穩壓電源適配器。全部開(kai)關穩壓電源適配器電路(lu)全是(shi)選用吸(xi)收合(he)并電子(zi)器件構成的，它的構造比較繁雜，可信性(xing)較弱。

　　②集(ji)(ji)成(cheng)(cheng)(cheng)電(dian)(dian)(dian)(dian)路式開(kai)關(guan)穩壓電(dian)(dian)(dian)(dian)源適(shi)配器(qi)。全部開(kai)關(guan)穩壓電(dian)(dian)(dian)(dian)源適(shi)配器(qi)電(dian)(dian)(dian)(dian)路或電(dian)(dian)(dian)(dian)路的(de)一部分是(shi)由集(ji)(ji)成(cheng)(cheng)(cheng)電(dian)(dian)(dian)(dian)路構成(cheng)(cheng)(cheng)的(de)，這(zhe)類集(ji)(ji)成(cheng)(cheng)(cheng)電(dian)(dian)(dian)(dian)路一般為厚膜電(dian)(dian)(dian)(dian)路。有(you)的(de)厚膜集(ji)(ji)成(cheng)(cheng)(cheng)電(dian)(dian)(dian)(dian)路中包含(han)電(dian)(dian)(dian)(dian)源開(kai)關(guan)管，有(you)的(de)則不包含(han)電(dian)(dian)(dian)(dian)源開(kai)關(guan)管。這(zhe)類電(dian)(dian)(dian)(dian)源開(kai)關(guan)電(dian)(dian)(dian)(dian)源適(shi)配器(qi)的(de)特(te)性(xing)是(shi)電(dian)(dian)(dian)(dian)路構造簡易，調節便捷，可信性(xing)高。

　　電(dian)源適配(pei)器(qi)的分類也有其他的一(yi)些分類方式 ，這兒也不(bu)一(yi)一(yi)詳細介紹了!
