style="text-indent:25px">在電源系統(tǒng)設(shè)計中，當一個大功率電源模塊的功率無法滿足系統(tǒng)的設(shè)計要求時，我們往往會考慮多個模塊的并聯(lián)使用。如果并聯(lián)設(shè)計不合理，就會導致并聯(lián)模塊輸出均流失效，會有燒壞大功率電源模塊，黑龍江大功率電源模塊銷售、甚至損壞后級系統(tǒng)的風險?，F(xiàn)在跟大家簡單分享一些造成大功率電源模塊并聯(lián)失效的真正原因，黑龍江大功率電源模塊銷售。目前電源系統(tǒng)的發(fā)展趨勢采用新型的功率器件實現(xiàn)小型、輕量、高效率的電源模塊化，通過并聯(lián)進行擴容，黑龍江大功率電源模塊銷售。電源并聯(lián)運行是電源產(chǎn)品模塊化、大容量化的一個有效方案，是電源技術(shù)發(fā)展的趨勢之一，是實現(xiàn)組合大功率電源系統(tǒng)的重點。大功率電源模塊輸出有單路輸出，雙路輸出及多路輸出。黑龍江大功率電源模塊銷售</p><div

style="text-indent:25px">大功率電源模塊老化測試的作用：在電源模塊進行老化時，使用電腦進行監(jiān)控，可以看出電源在工作狀態(tài)下的數(shù)據(jù)，反映出了電源的使用情況。長時間的老化，可以監(jiān)控出模塊性能隨溫度變化而產(chǎn)生的改變。在老化時，可以檢查出電源在生產(chǎn)過程中出現(xiàn)的問題。在老化時，模塊能夠長期穩(wěn)定運行，提高了產(chǎn)品的可靠性。一般在老化測試過程中，電源使用的情況比我們正常情況下所使用的環(huán)境更加惡劣，標準更加嚴格。只有這樣的測試才能反映出模塊電源的可靠性，是模塊電源廠家在保證產(chǎn)品質(zhì)量，提高產(chǎn)品競爭力和產(chǎn)品價格高低的重要流程之一。浦東新區(qū)大功率電源模塊供應公司一般輸出工作頻率越低，其體積越大，發(fā)熱量越大，輸出紋波越大。</p><div

style="text-indent:25px">散熱器翅片厚度的選擇也同樣會影響大功率電源模塊的散熱性能。在正常運行的情況下，由于導熱主要是沿著電源模塊的散熱器翅片縱向方向傳遞，因而翅片的厚度對于散熱器熱性能沒有太大的影響，翅片厚度的增加并沒有使熱源結(jié)溫降低很多，反而增加了散熱器的重量。為了保證散熱器翅片的硬度且易于加工，翅片硬度不能太薄，工程上一般會將散熱器翅片的厚度規(guī)定在≥1mm左右。散熱器翅片個數(shù)也同樣會影響到模塊電源的散熱性能。在模塊正常工作的前提下，隨著翅片數(shù)目的增多，熱源結(jié)溫會有所降低。但是超過某一數(shù)值之后，隨著翅片的增多，器件結(jié)溫不但沒有明顯變化反而散熱器的重量會明顯增加。同時，翅片數(shù)目增加有時還要考慮器件安裝的問題，有的器件安裝在散熱器兩翅片之間，如果翅片數(shù)太多，器件是不容易安裝在散熱器上的，因而工程師千萬不能盲目增加翅片的數(shù)目。</p><p style="text-indent:25px">大功率電源模塊目前大致可分為商用、工業(yè)、**等三個溫度等級,在使用上需要注意應用環(huán)境,避免出現(xiàn)工作溫度超過額定值而導致系統(tǒng)癱瘓。在產(chǎn)品技術(shù)手冊中一般還有EMC特性說明,標明了過的相對性等級,同時還會有參考應用電路,用戶可以根據(jù)自身實際情況來設(shè)計電路。可以避免因為裸機滿足不了要求,或者增加多個元件而重復修改等問題。常見于在調(diào)試雙路電源模塊時,出現(xiàn)了輔路輸出不斷重啟和電壓下跌等現(xiàn)象。這是由于主路負載出現(xiàn)輕載或空載,而輔路負載過重所導致。一般輔路電壓是依靠變壓器耦合穩(wěn)定輸出,其穩(wěn)定度與負載關(guān)系很大,因此,要求主路負載不小于額定的**功率電源模塊接地環(huán)路消除：遠程信號傳輸＼分布式電源供電系統(tǒng)。</p><div

style="text-indent:25px">大功率電源模塊結(jié)合了大部分必要的組件，以提供即插即用的解決方案，取代了40多種不同的元器件。這種整合可簡化并加速系統(tǒng)的設(shè)計，它也能明顯減少電源管理部分所占的電路板面積。為了達到所需要的電壓精度，這些電源模塊一般放在電路板上需要供電的芯片電路附近。但是隨著系統(tǒng)的復雜程度的提高，更大電流、更低電壓和更高頻率的系統(tǒng)中，布局更顯重要。電源模塊隨著導體特別是半導體的工藝發(fā)展，封裝技術(shù)和高頻軟開關(guān)的大量使用，電源模塊的規(guī)律密度越來越大，轉(zhuǎn)換的效率也越來越高。應用也越來越簡單。使得電源變的更輕，更小，更薄，噪音更低，可靠性和抗干擾性更加高的方向發(fā)展。電源檢測是綜合電源模塊在最大功率各式各樣負荷的具體表現(xiàn)。大功率電源模塊公司</p><p

style="text-indent:25px">有關(guān)統(tǒng)計數(shù)據(jù)表明，大功率電源模塊在預期有效時間內(nèi)失效的主要原因是外部故障條件下?lián)p壞。而正常使用失效的機率是很低的。因此延長模塊電源壽命、提高系統(tǒng)可靠性的重要一環(huán)是選擇保護功能完善的產(chǎn)品，即在模塊電源外部電路出現(xiàn)故障時模塊電源能夠自動進入保護狀態(tài)而不至于長久失效，外部故障消失后應能自動恢復正常。大功率電源模塊的保護功能應至少包括輸入過壓、欠壓、軟啟動保護；輸出過壓、過流、短路保護，大功率產(chǎn)品還應有過溫保護等。一般建議實際使用功率是模塊電源額定功率的30～80%為宜（具體比例大小還與其他因素有關(guān)，后面將會提到。），這個功率范圍內(nèi)模塊電源各方面性能發(fā)揮都比較充分而且穩(wěn)定可靠。負載太輕造成資源浪費，太重則對溫升、可靠性等不利。所有模塊電源均有一定的過載能力，例如某產(chǎn)品可達 110～120%，但是仍不建議長時間工作在過載條件下，畢竟這是一種短時應急之計。黑龍江大功率電源模塊銷售</p></p><br /><p>文章來源地址: http://www.cdcfah.com/cp/2902712.html</p></div></div></div></div></div><div id="hwy8v2f" class="page-right twoColRt"><div
