center;"> </p> <p>隨著SWITCH的開(kāi)關(guān)，電感L中的電流也是在輸出電流的有效值上下波動(dòng)的。所以在輸出端也會(huì)出現(xiàn)一個(gè)與SWITCH同頻率的紋波，一般所說(shuō)的紋波就是指這個(gè)。它與輸出電容的容量和ESR有關(guān)系。這個(gè)紋波的頻率與開(kāi)關(guān)電源相同，為幾十到幾百KHz??/p> <p> </p> <p>另外，SWITCH雙極晶體管或MOSFET的一般選擇，不管是哪一種，在其帶領(lǐng)的截止時(shí)間，會(huì)有一個(gè)上升時(shí)間和下降時(shí)間。此時(shí)在電路中會(huì)出現(xiàn)與開(kāi)關(guān)上升時(shí)間相同或頻率為奇數(shù)的頻率的噪音，通常為幾十兆赫。在反向恢復(fù)的瞬間，等效電路的電阻電容和電感串聯(lián)，將導(dǎo)致共振，噪聲頻率也為幾十兆赫。這2種噪聲通常被稱(chēng)為高頻噪聲，而振幅通常遠(yuǎn)大于紋波??/p> <p> </p> <p>如果是AC／DC變換器，除了上述兩種紋波(噪聲)以外，還有AC噪聲，頻率是輸入AC電源的頻率，??0??0Hz左右。還有一種共模噪聲，是由于很多開(kāi)關(guān)電源的功率器件使用外殼作為散熱器，產(chǎn)生的等效電容導(dǎo)致的??/p> <p> </p> <p>開(kāi)關(guān)電源的波紋有什么要求呢？主要是看產(chǎn)品的設(shè)計(jì)以及對(duì)負(fù)載的需?? 現(xiàn)在做一個(gè)好點(diǎn)的電源，輸出紋波電壓控制在以下200mV，小??0mV
