style="text-indent:25px">能量轉(zhuǎn)換系統(tǒng)必定存在能耗，雖然實際應(yīng)用中無法獲得100%的轉(zhuǎn)換效率，但是，一個高質(zhì)量的電源效率可以達(dá)到非常高的水平，效率接近95%。絕大多數(shù)電源IC

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(hù)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(hù)人員、負(fù)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。</p><p style="text-indent:25px">電源電壓應(yīng)力是保證電源可靠性的一個重要指標(biāo)。在電源中有許多器件都有規(guī)定較大耐壓值，比如：場效應(yīng)管的Vds和Vgs、二極管的反向耐壓、IC的較大VCC電壓以及輸入輸出電容的較大耐壓。所以我們設(shè)計充電電源模塊時必須要考慮到器件要承受的較大電壓。再根據(jù)電壓選擇適當(dāng)器件，再進(jìn)行實際測試加以驗證。但在測試時我們必須測試電源所有工作狀態(tài)的電壓應(yīng)力，以確保在惡劣的工作狀態(tài)下也能留出約10%的安全裕量。電源電流應(yīng)力往往與熱應(yīng)力密切相關(guān)，比如二極管SK54較大平均電流為5A，但是它是在滿足熱應(yīng)力降額前提下的極限參數(shù)。所以我們選擇器件時必須要同時滿足器件的電流應(yīng)力與熱應(yīng)力；在滿足器件熱應(yīng)力的前提下，選擇合適額定電流值的器件方可保證電源可靠性要求。直流開關(guān)電源主要由開關(guān)三極管和高頻變壓器組成。</p><div

style="text-indent:25px">對于充電電源模塊的應(yīng)力設(shè)計，重點關(guān)注場效應(yīng)管(MOS管)、二極管、變壓器、功率電感、電解電容、限流電阻等。保證全電壓范圍內(nèi)在穩(wěn)態(tài)、瞬態(tài)、短路等各種極限條件下都能有足夠的降額，以保障產(chǎn)品的可靠性。由于電源模塊越趨于小型化，功率密度相應(yīng)越來越高，電源模塊有關(guān)熱設(shè)計方面的問題。特別是對使用有電解電容的電源模塊，高溫會使電解電容的電解液加速消耗，減少電解電容的壽命。高溫會使元器件材料加速老化，例如使得變壓器漆包線的絕緣特性降低，導(dǎo)致絕緣耐壓不良甚至造成匝間短路。良好的熱設(shè)計不僅可延長電源模塊和其周圍元器件的使用壽命，還可使整個產(chǎn)品發(fā)熱均勻，減少故障的發(fā)生。湖北充電電源哪家便宜</p><p
