style="text-indent:25px">大功率電源模塊是系統(tǒng)與外部接觸、接口的，外部傳來的浪涌都經(jīng)過大功率電源模塊，所以需要浪涌防護電路。由于大功率電源模塊體積小，集成度高，長寧區(qū)大功率電源模塊公司，內(nèi)部的控制芯片和晶體管等器件較大耐壓和較大電流都比較極限，長寧區(qū)大功率電源模塊公司，長寧區(qū)大功率電源模塊公司，一個浪涌電壓過來可能就使模塊損壞失效，導(dǎo)致整個系統(tǒng)的癱瘓，即使沒有立馬損壞，器件受到應(yīng)力沖擊，也會影響壽命和可靠性，所以為了保證電源模塊持續(xù)可靠的應(yīng)用，一般都需要加上浪涌防護電路。大功率電源模塊受限于體積小，很多模塊內(nèi)部不能加上防浪涌電路，所以需要在模塊的外部加上防浪涌電路。大功率電源模塊輸出有單路輸出，雙路輸出及多路輸出。長寧區(qū)大功率電源模塊公司</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(dǎo)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。崇明區(qū)大功率電源模塊公司大功率電源模塊里要有無濾波設(shè)計、電源模塊所在的設(shè)備里有無安規(guī)要求（漏電流、絕緣耐壓、濕度要求）。</p><div
