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，電源適配器的種類(lei)也(ye)愈來(lai)愈多(duo)。電源適配器常有什么分(fen)類(lei)?

　　1、按調配方法分類

　　①脈沖寬度(du)調制型開關(guan)穩(wen)壓電源適配器(qi)。震蕩頻(pin)率保持一致，根(gen)據更改單脈沖總寬來(lai)更改和調整輸(shu)出工(gong)作電壓的尺寸，有時候(hou)根(gen)據抽樣電路、藕合電路等組(zu)成意見(jian)反饋閉(bi)環控(kong)(kong)制控(kong)(kong)制回路來(lai)平穩(wen)輸(shu)出工(gong)作電壓的力(li)度(du)。

　　②頻率(lv)調配(pei)型開關穩(wen)壓(ya)電(dian)源適配(pei)器。占空比保持(chi)一致，根據更改震(zhen)(zhen)蕩器的震(zhen)(zhen)蕩頻率(lv)來調整和平(ping)穩(wen)輸出(chu)工作電(dian)壓(ya)的力(li)度。

　　③混和調(diao)配型開(kai)關穩壓電源適配器。根據調(diao)整(zheng)通斷時(shi)間的(de)震蕩頻率來進行調(diao)整(zheng)和平(ping)穩輸出工作電壓的(de)力度。

　　2、按電路構造分類

　　①單件(jian)式開(kai)關穩(wen)壓電(dian)(dian)(dian)源適配器。全(quan)(quan)部(bu)開(kai)關穩(wen)壓電(dian)(dian)(dian)源適配器電(dian)(dian)(dian)路全(quan)(quan)是選(xuan)用吸收(shou)合并電(dian)(dian)(dian)子器件(jian)構成(cheng)的，它的構造比較繁雜，可信性較弱(ruo)。

　　②集(ji)(ji)(ji)成(cheng)電(dian)(dian)(dian)(dian)路(lu)式開(kai)(kai)(kai)關(guan)(guan)穩壓(ya)(ya)電(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)配器。全部開(kai)(kai)(kai)關(guan)(guan)穩壓(ya)(ya)電(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)配器電(dian)(dian)(dian)(dian)路(lu)或電(dian)(dian)(dian)(dian)路(lu)的(de)(de)(de)一部分是由集(ji)(ji)(ji)成(cheng)電(dian)(dian)(dian)(dian)路(lu)構成(cheng)的(de)(de)(de)，這(zhe)類(lei)集(ji)(ji)(ji)成(cheng)電(dian)(dian)(dian)(dian)路(lu)一般為(wei)厚膜(mo)電(dian)(dian)(dian)(dian)路(lu)。有(you)的(de)(de)(de)厚膜(mo)集(ji)(ji)(ji)成(cheng)電(dian)(dian)(dian)(dian)路(lu)中(zhong)包含電(dian)(dian)(dian)(dian)源(yuan)開(kai)(kai)(kai)關(guan)(guan)管，有(you)的(de)(de)(de)則(ze)不包含電(dian)(dian)(dian)(dian)源(yuan)開(kai)(kai)(kai)關(guan)(guan)管。這(zhe)類(lei)電(dian)(dian)(dian)(dian)源(yuan)開(kai)(kai)(kai)關(guan)(guan)電(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)配器的(de)(de)(de)特性(xing)是電(dian)(dian)(dian)(dian)路(lu)構造(zao)簡易，調(diao)節便捷(jie)，可信性(xing)高。

　　電源適配器的分類也(ye)有其(qi)他的一(yi)些分類方式 ，這兒也(ye)不一(yi)一(yi)詳細(xi)介紹了(le)!
