style="text-indent:25px">我們需要保證溫度范圍不僅要滿足工作實際需求，還要略有余量。不同的產(chǎn)品型號對于溫度范圍的要求是各不相同的，工程師在進行充電電源模塊溫度范圍選擇時，需要在較高溫度、較低溫度的上限以上進行考慮，以免出現(xiàn)溫度升高或降低之后系統(tǒng)性能不穩(wěn)定的情況。在滿足個條件的情況下，如果工程師出于對成本的控制問題，而選擇了較小溫度范圍的產(chǎn)品，那么就需要選擇功率或封裝更大一些的產(chǎn)品，這樣可以讓溫升降低一些，能夠從一定程度上緩解這一矛盾。從溫度范圍入手，進行模塊電源的綜合比較，可以幫助工程師快速決定封裝模式并進行成本預(yù)算，是一種比較方便快捷的挑選方法。</p><p style="text-indent:25px">充電電源“性能”和“成本”是一對相愛相殺的冤家，讓多少工程師面臨兩難的選擇，多少辛辛苦苦做的方案，由于成本問題不得不放棄。是為了性能不顧成本？還是為了成本**性能？怎樣平衡性能和成本，這是在產(chǎn)品設(shè)計中亙古不變的話題。對于同樣輸入輸出電壓的DC/DC電源模塊來說，輸出功率和工作溫度范圍是影響其成本的主要因素。電子器件工作溫度范圍一般分為：商業(yè)級（0~70℃）、工業(yè)級（-40~85℃）、車規(guī)級（-40~105℃）、**級（-55~125℃）等。由于溫度等級不同，對材料和制造工藝的要求不同，模塊成本就相差很大了。如果在體積（封裝形式）一定的條件下實際使用功率已經(jīng)接近模塊額定功率，那么模塊標(biāo)稱的溫度范圍就必須嚴(yán)格滿足實際使用需求甚至略有余量。如果由于成本考慮選擇了較小溫度范圍的產(chǎn)品，實際使用溫度已經(jīng)逼近模塊極限溫度的情況，怎么辦呢？這時可以采用降額使用的辦法，即選擇功率或封裝更大一些的產(chǎn)品，這樣“大馬拉小車”，溫升低，能夠從一定程度上緩解這一矛盾。高要求場合應(yīng)用要考慮采用高開關(guān)頻率的充電電源模塊。</p><div

style="text-indent:25px">電源在電子系統(tǒng)中，猶如人的心臟一樣，十分重要。選用合適的電源模塊，可省去電源設(shè)計、調(diào)試、生產(chǎn)、測試、老化、物料管理等諸多方面的麻煩，縮短產(chǎn)品開發(fā)周期，提高產(chǎn)品的整體可靠性和可維護性。那么該如何選擇呢？電源模塊按照輸入主要分為兩大類，AC和DC，當(dāng)輸入為交流電是選擇AC-DC電源模塊，交流輸入一般常見的有110VAC和220VAC兩種；當(dāng)輸入為直流時，選擇DC-DC電源模塊。隔離，可切斷浪涌等干擾信號的傳播路徑，其優(yōu)勢如：保護人員、負載設(shè)備免遭輸入端的瞬態(tài)高壓損害；去除隔離電路之間的接地環(huán)路以及改善抗干擾能力；在系統(tǒng)中輕松完成輸出接線，而不與主接地發(fā)生問題。開關(guān)電源的發(fā)展方向是高頻、高可靠、低耗、低噪聲、抗干擾和模塊化。靜安區(qū)充電電源咨詢</p><p style="text-indent:25px">充電電源常采用單相半控整流電路或不控整流電路（由無控制動能的整流二極管組成）。充電電源哪家好</p><p style="text-indent:25px">開關(guān)電源是利用現(xiàn)代電力電子技術(shù)，控制開關(guān)管開通和關(guān)斷的時間比率，維持穩(wěn)定輸出電壓的一種電源，開關(guān)電源一般由脈沖寬度調(diào)制（PWM）控制IC和MOSFET構(gòu)成。開關(guān)電源和線性電源相比，二者的成本都隨著輸出的功率的增加而增加，但二者增長速率各異。線性電源成本在某一輸出功率點上，反而高于開關(guān)電源，這一點稱為成本反轉(zhuǎn)點。隨著電力電子技術(shù)的發(fā)展和創(chuàng)新，使得開關(guān)電源技術(shù)也在不斷的創(chuàng)新，這一成本反轉(zhuǎn)點日益向低輸出電力端移動，這為開關(guān)電源提供了廣闊的發(fā)展空間。高壓直流電源帶來的具體好處：設(shè)備負載率高，加上節(jié)能休眠管理，提高系統(tǒng)整體效率；拓撲簡單，電池直接掛母排上，且電源模塊N+1冗余，可靠性高；電源模塊達到插拔式的便利程度，可在機柜內(nèi)按需在線擴容；并機擴容無交流電源幅度、相位和頻率的同步要求，機柜擴容簡單；標(biāo)準(zhǔn)機柜設(shè)備，可以集中能源池布置，也分散到網(wǎng)絡(luò)設(shè)備群中布置；現(xiàn)場更換故障電源模塊簡易，運維人員即可操作。充電電源哪家好</p></p><br
