走線阻抗大。電源模塊輸出與負載連接必然要有一段PCB走線，走線越長、走線越窄則它的等效電阻越大。等效電阻可以認為是串聯(lián)在負載的工作回路中，將起到分壓作用，因此導致負載兩端的電壓小于模塊的輸出電壓。此外，除了走線問題還有很多情況起到類似的作用，比如焊點接觸不良導致等效電阻增加，線路氧化或腐蝕導致等效電阻增加。<span style="font-size:12px;">防反接二極管。很多產(chǎn)品的AC和DC部分是不在一塊板上的，在生產(chǎn)或終端客戶使用中不可避免涉及到插拔電源連接器的情況。為防止此過程中的反接導致的硬件損壞，常串入一只二極管解決。以壓降0.7V的二極管為例，b1 b2間的電壓將比a1 a2間電壓小0.7V，這也就是上面所討論的輸入電壓偏低的情況，可以通過選擇壓降低的管子或者直接提高a1 a1間電壓的方法解決。</span> </p> <p> 江蘇智慧電-源電源是以電力電子學為重點的技術產(chǎn)品。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

電源模塊輸出有電壓但電壓低于標稱輸出值是測試過程中經(jīng)常遇到的問題，出現(xiàn)這種情況的原因無非有兩種，一是電源模塊為不良品或損壞，二是使用方法問題。下文天磁將重點討論使用方法導致的電源模塊輸出電壓低的情況。<span style="font-size:12px;">輸入電壓偏低是容易被忽略的情況，當輸出有問題時我們應該檢查輸入是否正常。對于輸入為定壓或寬壓的電源模塊，當輸入值偏低時將導致輸出值也偏低。當然，這種情況是有限度的，對于一個特定的模塊來說，當輸入電壓過低時將導致其不能工作，無輸出電壓。</span><span style="font-size:12px;">輸出過載是指負載工作功率大于電源模塊的額定輸出功率，過載情況下電源模塊的輸出電壓明顯被拉低。以ZY0505FS-1W為例，當負載電流增大到300mA時，輸出電壓只有4.5V。持續(xù)過載將影響到電源模塊的工作效率、穩(wěn)定性以及散熱情況，導致模塊使用壽命減少。若是過載導致的輸出電壓過低，則需要提升電源模塊的輸出功率，可以選擇2W或3W的模塊。</span>

style="text-indent:25px">整機采用開關電源技術、智能充電技術，可靠性高，對電網(wǎng)波動適應性強。穩(wěn)定性高：開關電源控制芯片采用進口級集成電路，穩(wěn)定可靠，延長電池的壽命；強制風冷式散熱，負荷自動均分，故障率低，可靠性高。采用脈寬調(diào)制技術，有效率，高功率因數(shù)；紋波系數(shù)低，對其它設備干擾小。充電特性：采用智能充電技術，充電過程無須人工干預。嚴格按照蓄電池充電特性曲線進行充電，采用“恒流→恒壓限流→涓流浮充”智能三階段充電模式，使每節(jié)電池都能夠較快地充分地充滿電，避免過充電，完全做到全自動工作狀態(tài)，無需人工值守。適用電池范圍廣：充電電流可在10%-額定值內(nèi)任意設定，且不受輸入交流電壓變化的影響，在恒流充電期間電流維持不變，無需人為再調(diào)整。還可以直接安裝在導軌上。</p><div

就和其它傳統(tǒng)行業(yè)一樣，UPS行業(yè)也遇到了競爭加劇和產(chǎn)業(yè)升級的壓力：產(chǎn)品功能同質(zhì)化嚴重，各種山寨劣質(zhì)產(chǎn)品層出不窮，為了追求市場，不斷壓低產(chǎn)品銷售價格，而為了尋求利潤空間，就不得不控制成本，偷工減料，降低產(chǎn)品質(zhì)量。這種惡性競爭的后果就是忽視了客戶的需求，**終的結果還是傷害整個行業(yè)。<span

智慧電源可分別對每路進行電壓、電流、及電路采集。上海智慧燈桿電-源方案</p><p style="text-indent:25px">電源就是把其他形式的能量轉化成電能的裝置。上海智慧燈桿電-源方案</p><p> 電源模塊的拓撲結構有多種，反激、正激、推挽、半橋、全橋多種，每種因為其原理的不同，也表現(xiàn)為在某些特性指標方面的優(yōu)越性。反激電源在開關的一個周期中，充電的時段沒有放電，就是因為這個特性，其時間響應特性、紋波特性就很難做到很好，雖然可以通過大的儲能電容協(xié)助解決一點，但原理性缺點終歸是硬傷，智力不足是可以通過勤勞來彌補，但補來補去遇到臨界難題的時候終歸跨不過某個坎兒。漏感也大等等問題，但其優(yōu)點是電路簡單，成本低，體積小，不必加磁復位繞組，而且輸入電壓范圍比較寬。也正因為此，才有了其占總電源市場7成以上的份額。正激電源輸出電壓瞬態(tài)控制特性較好，負載能力較強，但其缺點也同樣，多用一個大儲能濾波電感和一個續(xù)流二極管、體積大、變壓器初級線圈反電動勢電壓高，對開關管的要求較高（容易擊穿損壞）。上海智慧燈桿電-源方案</p><p
