P耗越小，則效率越高，溫升就低，壽命更長。除了滿載正常損耗外，還有兩個損耗值得注意：空載損耗和短路損耗（輸出短路時模塊電源損耗），因?yàn)檫@兩個損耗越小，表明模塊效率越高，特別是短路未能及時采取措施的情況下，可能持續(xù)較長時間，短路損耗越小則因此失效的機(jī)率也減小。當(dāng)然損耗越小也更符合節(jié)能的要求?？傊?，電源模塊和其它元器件一樣只有精心選擇、合理應(yīng)用才能使其性能得到較大發(fā)揮，可靠性得到充分保障，電源模塊也才會被更地采用！</p><p style="text-indent:25px">充電電源模塊，工作頻率一般而言工作頻率越高，輸出紋波噪聲就更小，電源動態(tài)響應(yīng)也更好，但是對元器件特別是磁性材料的要求也越高，成本會有增加，所以國內(nèi)電源模塊產(chǎn)品開關(guān)頻率多為在 300kHz以下，甚至有的只有100kHz左右，這樣就難以滿足負(fù)載變條件下動態(tài)響應(yīng)的要求，因此高要求場合應(yīng)用要考慮采用高開關(guān)頻率的產(chǎn)品。另外一方面當(dāng)電源模塊開關(guān)頻率接近信號工作頻率時容易引起差拍振蕩，選用時也要考慮到這一點(diǎn)。5．隔離電壓一般場合使用對電源模塊隔離電壓要求不是很高，但是更高的隔離電壓可以保證電源模塊具有更小的漏電流，更高的安全性和可靠性，并且EMC特性也更好一些，因此目前業(yè)界普遍的隔離電壓水平為1500VDC以上。電源設(shè)計中即使是普通的直流到直流開關(guān)轉(zhuǎn)換器的設(shè)計都會出現(xiàn)一系列問題，尤其在高功率電源設(shè)計中更是如此。</p><div

的工作效率可以在特定的工作條件下測得，數(shù)據(jù)資料中給出了這些參數(shù)。一般廠商會給出實(shí)際測量的結(jié)果，但我們只能對我們自己的數(shù)據(jù)擔(dān)保。圖給出了一個SMPS 降壓轉(zhuǎn)換器的電路實(shí)例，轉(zhuǎn)換效率可以達(dá)到97%，即使在輕載時也能保持較高效率。采用什么秘訣才能達(dá)到如此高的效率？我們從了解SMPS 損耗的公共問題開始，開關(guān)電源的損耗大部分來自開關(guān)器件(MOSFET 和二極管)，另外小部分損耗來自電感和電容。但是，如果使用非常廉價的電感和電容(具有較高電阻)，將會導(dǎo)致?lián)p耗明顯增大。模塊損耗 P耗越小，則效率越高，溫升就低，壽命更長。崇明區(qū)充電電源種類</p><p
