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(yu)來愈(yu)多(duo)。電源適配(pei)器(qi)常(chang)有什么分類(lei)?

　　1、按調配方法分類

　　①脈(mo)沖寬度(du)調(diao)制(zhi)型開關穩(wen)(wen)壓(ya)電(dian)(dian)源適配(pei)器(qi)。震蕩頻率保持一致，根(gen)據更(geng)改單(dan)脈(mo)沖總寬來更(geng)改和調(diao)整輸出工作電(dian)(dian)壓(ya)的尺寸，有時候根(gen)據抽(chou)樣電(dian)(dian)路、藕合電(dian)(dian)路等組成(cheng)意見反饋閉環控(kong)制(zhi)控(kong)制(zhi)回路來平穩(wen)(wen)輸出工作電(dian)(dian)壓(ya)的力度(du)。

　　②頻(pin)率(lv)調配(pei)型開(kai)關穩壓電(dian)源適配(pei)器(qi)。占空比保持(chi)一致，根據更改震(zhen)蕩(dang)器(qi)的震(zhen)蕩(dang)頻(pin)率(lv)來調整和(he)平穩輸出工(gong)作電(dian)壓的力(li)度。

　　③混和(he)調(diao)配(pei)型開(kai)關穩(wen)壓電源適配(pei)器。根據調(diao)整通斷時間(jian)的震蕩頻率來進行調(diao)整和(he)平穩(wen)輸(shu)出(chu)工作電壓的力度。

　　2、按電路構造分類

　　①單件(jian)式開關穩壓(ya)電(dian)源(yuan)適配器(qi)。全(quan)部開關穩壓(ya)電(dian)源(yuan)適配器(qi)電(dian)路全(quan)是選用吸收合(he)并電(dian)子器(qi)件(jian)構(gou)成的，它的構(gou)造比較繁雜，可信性較弱。

　　②集(ji)成(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)式開(kai)(kai)關穩(wen)壓(ya)電(dian)(dian)(dian)(dian)(dian)(dian)源適配器。全部(bu)開(kai)(kai)關穩(wen)壓(ya)電(dian)(dian)(dian)(dian)(dian)(dian)源適配器電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)或電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)的(de)一部(bu)分是由集(ji)成(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)構成(cheng)的(de)，這類集(ji)成(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)一般為厚膜(mo)電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)。有(you)的(de)厚膜(mo)集(ji)成(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)中包含電(dian)(dian)(dian)(dian)(dian)(dian)源開(kai)(kai)關管(guan)，有(you)的(de)則(ze)不包含電(dian)(dian)(dian)(dian)(dian)(dian)源開(kai)(kai)關管(guan)。這類電(dian)(dian)(dian)(dian)(dian)(dian)源開(kai)(kai)關電(dian)(dian)(dian)(dian)(dian)(dian)源適配器的(de)特(te)性是電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)構造簡易，調節便(bian)捷，可信性高。

　　電源(yuan)適配器的分類也有(you)其他的一些分類方(fang)式 ，這兒也不一一詳(xiang)細介紹(shao)了!
