隨著電(dian)源(yuan)技術的(de)開發，現在，電(dian)子(zi)儀器(qi)(qi)設備在性能(neng)上(shang)更加(jia)安全可靠，功(gong)能(neng)上(shang)不斷地(di)增強，使(shi)用(yong)上(shang)自動化程度(du)也越(yue)來越(yue)高。而這些(xie)電(dian)子(zi)技術及其應用(yong)不斷發展都(dou)(dou)離不開電(dian)源(yuan)適配(pei)器(qi)(qi)，電(dian)源(yuan)適配(pei)器(qi)(qi)在計算機、通信、航(hang)天(tian)(tian)、家電(dian)等方面都(dou)(dou)得到了越(yue)來越(yue)廣泛(fan)的(de)應用(yong)，電(dian)源(yuan)適配(pei)器(qi)(qi)的(de)類型也越(yue)來越(yue)多。今天(tian)(tian)飛天(tian)(tian)鷹就簡單的(de)為(wei)大家下(xia)盤(pan)點(dian)一(yi)下(xia)，適配(pei)器(qi)(qi)都(dou)(dou)有哪些(xie)分類？

1、按調制方式分類

①脈(mo)寬調制型(xing)開關穩壓(ya)(ya)電(dian)(dian)(dian)(dian)源適配器(qi)。振蕩(dang)頻率保持不變(bian)，通(tong)過(guo)改變(bian)脈(mo)沖寬度來改變(bian)和調節(jie)輸出(chu)電(dian)(dian)(dian)(dian)壓(ya)(ya)的大小，有時通(tong)過(guo)取樣電(dian)(dian)(dian)(dian)路、耦合電(dian)(dian)(dian)(dian)路等構成反饋閉環回路來穩定輸出(chu)電(dian)(dian)(dian)(dian)壓(ya)(ya)的幅度。

②頻率調制型開關穩壓電源適配器。占(zhan)空(kong)比保持不變(bian)，通過改變(bian)振(zhen)蕩器的振(zhen)蕩頻率來調節和穩定輸出(chu)電壓的幅度(du)。

③混合調(diao)制型開關穩壓電源適配(pei)器。通(tong)過調(diao)節導通(tong)時間的振蕩頻率來完(wan)成(cheng)調(diao)節和穩定輸出電壓的幅度(du)。

2、按激勵方式分類(lei)

①他(ta)激式開關穩(wen)壓電源適配器(qi)。電路中設有激勵信號的振(zhen)蕩器(qi)。

②自激式開關穩壓電源適(shi)配器。開關管兼作振蕩(dang)器中的振蕩(dang)管。

3、按電(dian)路結構分類

①散件式開關(guan)穩(wen)(wen)壓電源適(shi)配器。整個開關(guan)穩(wen)(wen)壓電源適(shi)配器電路都是采用分立元器件組(zu)成的，它(ta)的結(jie)構較為復雜，可(ke)靠性較差(cha)。

②集成(cheng)電(dian)(dian)(dian)路式開(kai)(kai)關(guan)穩(wen)壓(ya)(ya)電(dian)(dian)(dian)源(yuan)適配器(qi)(qi)。整個開(kai)(kai)關(guan)穩(wen)壓(ya)(ya)電(dian)(dian)(dian)源(yuan)適配器(qi)(qi)電(dian)(dian)(dian)路或(huo)電(dian)(dian)(dian)路的一部分是由集成(cheng)電(dian)(dian)(dian)路組(zu)成(cheng)的，這(zhe)種集成(cheng)電(dian)(dian)(dian)路通常為厚膜電(dian)(dian)(dian)路。有的厚膜集成(cheng)電(dian)(dian)(dian)路中(zhong)包(bao)(bao)括開(kai)(kai)關(guan)管，有的則不包(bao)(bao)括開(kai)(kai)關(guan)管。這(zhe)種開(kai)(kai)關(guan)電(dian)(dian)(dian)源(yuan)適配器(qi)(qi)的特點是電(dian)(dian)(dian)路結構簡(jian)單，調(diao)試方(fang)便(bian)，可(ke)靠性高。
