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)也愈來愈多(duo)。電(dian)源適配器常(chang)有什么分類(lei)?

　　1、按調配方法分類

　　①脈沖(chong)寬(kuan)(kuan)度調制(zhi)(zhi)型(xing)開關穩壓(ya)(ya)電(dian)(dian)源適配器。震蕩頻(pin)率保持(chi)一(yi)致，根(gen)據(ju)更(geng)改單脈沖(chong)總寬(kuan)(kuan)來更(geng)改和調整輸出工作(zuo)電(dian)(dian)壓(ya)(ya)的(de)尺寸(cun)，有時候(hou)根(gen)據(ju)抽樣電(dian)(dian)路(lu)(lu)、藕合電(dian)(dian)路(lu)(lu)等組成意見反(fan)饋閉環控(kong)制(zhi)(zhi)控(kong)制(zhi)(zhi)回(hui)路(lu)(lu)來平穩輸出工作(zuo)電(dian)(dian)壓(ya)(ya)的(de)力度。

　　②頻率調(diao)配型開關穩(wen)壓(ya)電源(yuan)適配器(qi)(qi)。占空比(bi)保持一(yi)致，根(gen)據更改震(zhen)蕩器(qi)(qi)的震(zhen)蕩頻率來調(diao)整(zheng)和平穩(wen)輸出工(gong)作電壓(ya)的力(li)度。

　　③混(hun)和調(diao)配型開關(guan)穩(wen)壓電源適配器。根據調(diao)整(zheng)通斷時間的震蕩頻率來進行調(diao)整(zheng)和平穩(wen)輸(shu)出工作(zuo)電壓的力度(du)。

　　2、按電路構造分類

　　①單件式開(kai)(kai)關穩壓電(dian)源(yuan)適(shi)配器。全部開(kai)(kai)關穩壓電(dian)源(yuan)適(shi)配器電(dian)路全是選用吸收(shou)合(he)并(bing)電(dian)子器件構成的，它的構造比(bi)較(jiao)繁雜，可信性(xing)較(jiao)弱。

　　②集成(cheng)電(dian)(dian)(dian)(dian)路(lu)(lu)式(shi)開關(guan)(guan)(guan)穩壓電(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)配(pei)器(qi)。全部(bu)(bu)開關(guan)(guan)(guan)穩壓電(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)配(pei)器(qi)電(dian)(dian)(dian)(dian)路(lu)(lu)或電(dian)(dian)(dian)(dian)路(lu)(lu)的一部(bu)(bu)分是(shi)由集成(cheng)電(dian)(dian)(dian)(dian)路(lu)(lu)構成(cheng)的，這類集成(cheng)電(dian)(dian)(dian)(dian)路(lu)(lu)一般為(wei)厚膜(mo)電(dian)(dian)(dian)(dian)路(lu)(lu)。有的厚膜(mo)集成(cheng)電(dian)(dian)(dian)(dian)路(lu)(lu)中(zhong)包(bao)含(han)電(dian)(dian)(dian)(dian)源(yuan)開關(guan)(guan)(guan)管，有的則(ze)不包(bao)含(han)電(dian)(dian)(dian)(dian)源(yuan)開關(guan)(guan)(guan)管。這類電(dian)(dian)(dian)(dian)源(yuan)開關(guan)(guan)(guan)電(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)配(pei)器(qi)的特性是(shi)電(dian)(dian)(dian)(dian)路(lu)(lu)構造(zao)簡易(yi)，調節便捷(jie)，可(ke)信性高。

　　電源(yuan)適配器的分(fen)類(lei)也(ye)有(you)其(qi)他的一些分(fen)類(lei)方式(shi) ，這兒也(ye)不一一詳細介紹了!
