style="text-indent:25px">AC/DC變換是將交流變換為直流，其功率流向可以是雙向的，功率流由電源流向負(fù)載的稱為“整流”，功率流由負(fù)載返回電源的稱為“有源逆變”。AC/DC變換器輸入為50/60Hz的交流電，因必須經(jīng)整流、濾波，因此體積相對(duì)較大的濾波電容器是必不可少的，同時(shí)因遇到安全標(biāo)準(zhǔn)（如UL、CCEE等）及EMC指令的限制（如IEC、、FCC、CSA），交流輸入側(cè)必須加EMC濾波及使用符合安全標(biāo)準(zhǔn)的元件，這樣就限制AC/DC電源體積的小型化，另外，由于內(nèi)部的高頻、高壓、大電流開(kāi)關(guān)動(dòng)作，使得解決EMC電磁兼容問(wèn)題難度加大，也就對(duì)內(nèi)部高密度安裝電路設(shè)計(jì)提出了很高的要求，由于同樣的原因，高電壓、大電流開(kāi)關(guān)使得電源工作損耗增大，限制了AC/DC變換器模塊化的進(jìn)程，因此必須采用電源系統(tǒng)優(yōu)化設(shè)計(jì)方法才能使其工作效率達(dá)到一定的滿意程度。AC/DC變換按電路的接線方式可分為，半波電路、全波電路。按電源相數(shù)可分為，單相、三相、多相。按電路工作象限又可分為一象限、二象限、三象限、四象限。
