style="text-indent:25px">大家可能遇到在調(diào)試雙路大功率電源模塊時，出現(xiàn)輔路輸出不斷重啟，或則輔路電壓下跌很嚴重的現(xiàn)象。此現(xiàn)象70%是由于主路負載出現(xiàn)空載或則輕載，同時輔路負載很重導(dǎo)致。故電源主路一般會要求負載不小于額定負載的10%~20%。原理上主要是因為輔路輸出電壓是依靠變壓器耦合穩(wěn)定輸出，輔路電壓的穩(wěn)定度與負載關(guān)系較大。市面上大部分大功率電源模塊不支持熱插拔，所謂熱插拔就是在帶電帶負載的情況下對模塊進行插拔操作。一般需要熱插拔的模塊都是冗余模塊及備用模塊，此類大功率電源模塊都有加入熱插拔控制電路，防止插拔時產(chǎn)生尖峰電壓損壞電源。河南大功率電源模塊定做大功率電源模塊輸出端負載過輕，輕于10%的額定負載造成電壓偏高。</p><div

style="text-indent:25px">大功率電源模塊有以下多個優(yōu)點：每一模塊可以分別加以嚴格測試，以確保其高度可靠，其中包括通電測試，以便剔除不合規(guī)格的產(chǎn)品。相較之下，集成式的解決方案便較難測試，因為整個供電系統(tǒng)與電路上的其他功能系統(tǒng)緊密聯(lián)系一起。不同的供應(yīng)商可以按照現(xiàn)有的技術(shù)標(biāo)準設(shè)計同一大小的模塊，為設(shè)計電源供應(yīng)器的工程師提供多種不同的選擇。每一模塊的設(shè)計及測試都按照標(biāo)準性能的規(guī)定進行，有助減少采用新技術(shù)所承受的風(fēng)險。若采用集成式的解決方案，一旦電源供應(yīng)系統(tǒng)出現(xiàn)問題，便需要將整塊主機板更換;若采用模塊式的設(shè)計，只要將問題模塊更換便可，這樣有助節(jié)省成本及開發(fā)時間。</p><p style="text-indent:25px">大功率電源模塊在電壓轉(zhuǎn)換過程中有能量損耗，產(chǎn)生熱能導(dǎo)致模塊發(fā)熱，降低電源的轉(zhuǎn)換效率，影響電源模塊正常工作，但什么情況下會造成大功率電源模塊發(fā)熱較嚴重呢？負載過流，超出數(shù)據(jù)手冊應(yīng)用范圍使得內(nèi)部關(guān)鍵器件溫度飆升；環(huán)境溫度過高或散熱不良；其他大發(fā)熱源熱傳遞。使用線性電源時要加散熱片,或選擇效率高的開關(guān)電源；輸出功率更大的模塊，確保有70%~80%的負載降額；降低環(huán)境溫度，保持散熱良好。噪聲是衡量電源模塊優(yōu)劣的一大關(guān)鍵指標(biāo)，在應(yīng)用電路中，模塊周邊元器件的設(shè)計布局等也會影響輸出噪聲，哪些因素對輸出噪聲有較大影響呢？電源模塊與主電路噪聲敏感元件距離過近；主電路噪聲敏感元件的電源輸入端處未接去耦電容；多路系統(tǒng)中各單路輸出的電源模塊之間產(chǎn)生差頻干擾；地線處理不合理；電源模塊輸入端的噪聲過大，未處理，直接耦合到電源模塊輸出端；大致上大功率電源可分為線性電源和開關(guān)電源兩類。</p><div

style="text-indent:25px">當(dāng)今電源系統(tǒng)的設(shè)計，對于電子設(shè)計人員來說遇到了極大的挑戰(zhàn)。他們要利用有限的資源和空間，在短時間內(nèi)設(shè)計出靈活、高效、可靠和具有競爭力的電源系統(tǒng)。大功率電源模塊是目前設(shè)計人員的較好選擇。以模塊式電源取代分立元件設(shè)計方案，好比用微信息處理器件代替集成電路方塊，它可更靈活、更快捷地完成系統(tǒng)及開發(fā)，縮短開發(fā)或更改設(shè)計所花費的時間，節(jié)省人力及技術(shù)投資。設(shè)計簡單。只需1個大功率電源模塊，配上少量分立元件，即可獲得電源。質(zhì)優(yōu)可靠。大功率電源模塊一般均采用全自動化生產(chǎn)，并配以高科技生產(chǎn)技術(shù)，因此品質(zhì)穩(wěn)定、可靠。　　河南大功率電源模塊定做</p></p><br
