磁珠、電容、二極管、電阻…都具有類似的潛規(guī)則，只是我們不太注意而已。電源模塊的拓?fù)浣Y(jié)構(gòu)有多種，反激、正激、推挽、半橋、全橋多種，每種因?yàn)槠湓淼牟煌?，也表現(xiàn)為在某些特性指標(biāo)方面的優(yōu)越性。反激電源在開關(guān)的一個(gè)周期中，充電的時(shí)段沒有放電，就是因?yàn)檫@個(gè)特性，其時(shí)間響應(yīng)特性、紋波特性就很難做到很好，雖然可以通過大的儲(chǔ)能電容協(xié)助解決一點(diǎn)，但原理性缺點(diǎn)終歸是硬傷。漏感也大等等問題，但其優(yōu)點(diǎn)是電路簡單，成本低，體積小，不必加磁復(fù)位繞組，而且輸入電壓范圍比較寬。也正因?yàn)榇?，才有了其占總電源市?成以上的份額。 </p> <p> <br /> </p><p> 正激電源輸出電壓瞬態(tài)控制特性較好，負(fù)載能力較強(qiáng)，但其缺點(diǎn)也同樣，多用一個(gè)大儲(chǔ)能濾波電感和一個(gè)續(xù)流二極管、體積大、變壓器初級線圈反電動(dòng)勢電壓高，對開關(guān)管的要求較高。<span style="font-size:12px;">推挽式電源電流瞬態(tài)響應(yīng)速度很高，電壓輸出特性很好，在所有拓?fù)浣Y(jié)構(gòu)中，是利用率比較高的一種開關(guān)電源，無漏磁，驅(qū)動(dòng)電路簡單。但其缺點(diǎn)是兩個(gè)開關(guān)器件需要很高的耐壓值；要有兩組初級線圈，對于小功率輸出的推挽式開關(guān)電源是個(gè)缺點(diǎn)。若兩個(gè)正激式變換器不完全對稱或平衡，經(jīng)過幾個(gè)周期累積的偏磁，會(huì)使磁芯進(jìn)入飽和，導(dǎo)致高頻變壓器勵(lì)磁電流過大，甚至損壞開關(guān)管。橋式開關(guān)電源輸出功率很大，工作效率很高，開關(guān)管的耐壓值要求比較低，變壓器初級線圈只需要一個(gè)繞組。</span>

style="font-size:12px;">該類電源優(yōu)點(diǎn)是穩(wěn)定性高，紋波小，可靠性高，易做成多路，輸出連續(xù)可調(diào)的成品。缺點(diǎn)是體積大、較笨重、效率相對較低。這類穩(wěn)定電源又有很多種，從輸出性質(zhì)可分為穩(wěn)壓電源和穩(wěn)流電源及集穩(wěn)壓、穩(wěn)流于一身的穩(wěn)壓穩(wěn)流（雙穩(wěn)）電源。從輸出值來看可分定點(diǎn)輸出電源、波段開關(guān)調(diào)整式和電位器連續(xù)可調(diào)式幾種。從輸出指示上可分指針指示型和數(shù)字顯示式型等等。</span>
