style="text-indent:25px">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。總之要么選擇寬溫度范圍的產(chǎn)品，功率利用更充分，封裝也更小一些，但價格較高；要么選擇一般溫度范圍產(chǎn)品，價格低一些，功率余量和封裝形式就得大一些。到底怎樣選擇，就需要根據(jù)實際的情況，綜合考慮了。</p><p> 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)動電路簡單。但其缺點是兩個開關(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)電源是個缺點。若兩個正激式變換器不完全對稱或平衡，經(jīng)過幾個周期累積的偏磁，會使磁芯進(jìn)入飽和，導(dǎo)致高頻變壓器勵磁電流過大，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繞組。缺點是效率低，會出現(xiàn)半導(dǎo)通區(qū)，損耗大。以上各種問題都是因為其拓?fù)浣Y(jié)構(gòu)的先天優(yōu)勢和先天缺點造成的，雖然我們可以將電源模塊當(dāng)成黑匣子，但這也是我們在選擇電源時要關(guān)注的一個點。因為能完成同樣功能的設(shè)計方案，一個很輕松地完成，一個要費很大的勁才能完成。我們平時用的充電器或電池等供電裝置到底是不是電源呢？</p><div

智能充電機一般是采用測壓裝置的，什么是測壓裝置呢?這是一種可以讓電流自己中端停止充電的裝置。我們平時使用的充電器是沒有女裝這種裝置的，所以我們的充電器發(fā)熱會比較嚴(yán)重，嚴(yán)重的時候會讓電器設(shè)備和損壞。智能充電機的價格會比較貴，因為采用的設(shè)備和控制系統(tǒng)比較高級，是一種安全可靠的高性價比充電機。智能充電機的原理也是非常的簡單的，因為里面安裝了測壓的裝置，采用了金屬隔板，我們在進(jìn)行充電的時候，測壓裝置就會自動的進(jìn)行測壓。當(dāng)我們的設(shè)備充電完成的時候，充電器就會自動的轉(zhuǎn)化里面的電流，電流會被轉(zhuǎn)化成涓流。涓流充電是非常慢的，幾乎可以說是停止充電的狀態(tài)。智能充電機采用的控制設(shè)備也是有區(qū)別的，但是主要是利用某些轉(zhuǎn)變電流的裝置進(jìn)行控制電流的流通，從而達(dá)到一個充滿電就會自動斷電的效果。智能的充電機的安全性能是比較高的，它可以完美的解決過度充電的問題，可以讓設(shè)備在充電的時候更加的安全，而且不會浪費電，是一種安全環(huán)保的設(shè)備。兩路12V輸出，總功率150W。天津智慧路燈電-源生產(chǎn)基地</p><p

style="text-indent:25px">電源是電力電子學(xué)的技術(shù)產(chǎn)品?！半娫础笔墙K端產(chǎn)品，“電源”產(chǎn)品是“電力電子”應(yīng)用技術(shù)的具體產(chǎn)品體現(xiàn)。電力電子電源通常指采用電力電子技術(shù)的電源產(chǎn)品，是電力電子設(shè)備中重要組成成員。以電力電子學(xué)為**技術(shù)的電源產(chǎn)業(yè)，電源行業(yè)是各類高科技產(chǎn)業(yè)發(fā)展的基礎(chǔ)，所有的高精尖科技設(shè)備都需要電力電子電源的技術(shù)支持。隨著I T產(chǎn)業(yè)、C I產(chǎn)業(yè)、P C機飛速發(fā)展。帶動電源行業(yè)的騰飛。電源行業(yè)運用于各行各業(yè)，以國民經(jīng)濟密不可分。中國電源企業(yè)成立時間普遍較短，成立時間超過10年的企業(yè)*占11.3個百分點，同時隨著我國開放的逐漸加深，外資企業(yè)與合資企業(yè)逐漸增多，促使競爭加劇，同時也是對本土企業(yè)的機會與挑戰(zhàn)。對于電源企業(yè)的經(jīng)營狀況，由于整體需求旺盛，雖然競爭加劇，但是行業(yè)平均收入與利潤均有所增加。同時為了企業(yè)在未來有進(jìn)一步競爭的潛力，中國電源企業(yè)都加大研發(fā)的力度，增加研發(fā)人員。從上個世紀(jì)90 年代，電源行業(yè)呈式發(fā)展，企業(yè)數(shù)量從90 年代初期的幾百家增加到至今的幾萬家，產(chǎn)量從90 年代的十幾億元增加到至今的幾百億元。并還在進(jìn)一步飛速發(fā)展。天津智慧電-源方案</p><p
