電源適配器就是將AC輸入轉為DC輸出的設備，它工作的原理主要就是靠IC控制電源開關閉合，維持穩(wěn)定電壓輸出的。 </p> <p> 電源適配器中的濾波電容通常使用點解電容，點解電容在工作過程中溫度會很高，它的使用壽命是和溫度成反比的，陜西電源批發(fā)，溫度越高，使用壽命越短。電容的好壞***影響其壽命，一般的公司采用的是壽命幾千個小時的電容，與此相對電源適配器的壽命也就**收到限制，我們采用的是行業(yè)排行**的廠家電源，電容壽命一般都是在50000個小時以上，大約在50000個小時候濾波電容會鼓包，電源適配器也就不再工作。 </p> <p> 那就需要把控好電源生命周期中的兩個重要環(huán)節(jié)：電源的研發(fā)、電源的生產。電源研發(fā)需要保證電源的性能滿足我們的規(guī)格書要求，保證在電源正常生命周期中的電源性能指標。 </p> <p> 如何延長電源適配器的壽命，這里對于適配器的使用有一下幾點建議: </p> <p> 1. 盡量避免在潮濕的或者容易接觸到水的環(huán)境中使用，當然防水電源除外。 </p> <p> 2. 不要使用和電源適配器不匹配的輸入電壓，以免引起輸入過流過壓現象而損壞，陜西電源批發(fā)。 </p> <p> 3. 在使用電源適配器時，保護好電線不要過彎或者折死，以及摩擦，陜西電源批發(fā)。 </p> <p> 4. 電源適配器的放置，應該避免陽光直射的環(huán)境中使用。 </p> <p> 5. 在不使用電源適配器時，應盡量切斷電源，減少電源內部損耗。 </p> <p> <br /> </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="陜西電源批發(fā)"

電源質量不好，不但會影響設備穩(wěn)定工作，減少器件使用壽命，嚴重時可能燒毀芯片，造成不可估量的損失，所以說電源是**重要的配件也不為過。 </p> <p> 除了我們平時經常關注的過流保護、短路保護、環(huán)境適應要求、使用壽命等標準，還有一些是我們容易忽略的電源輸出/輸入特性。下面我們就來給大家簡單的介紹一下這些技術規(guī)格。 </p> <p> 一、輸出特性： </p> <p> 維持時間：<span style="font-size:12px;">交流電源斷電到輸出電壓下降至下限值的時間段</span> </p> <p> 過沖幅度：<span style="font-size:12px;">由某一影響量瞬變而引起輸出直流電壓超過穩(wěn)壓值的現象為過沖。過沖幅度為輸出電壓偏離正常值的比較大瞬變幅度</span> </p> <p> 暫態(tài)恢復時間：<span style="font-size:12px;">由某一影響量瞬變，輸出電壓從***次離開穩(wěn)壓區(qū)到***進入穩(wěn)壓區(qū)的時間間隔。</span> </p> <p> 負載穩(wěn)定度：<span style="font-size:12px;">在所有其他影響量保持不變時，由于負載的變化所引起輸出電壓的相對變化量。</span> </p> <p> 電壓穩(wěn)定度：<span style="font-size:12px;">在所有其他影響量保持不變時，由于輸入電壓的變化，所引起的電壓的相對變化量。</span> </p> <p> 輸出波紋及噪聲：<span style="font-size:12px;">輸出直流電壓中所包括的交流分量峰-峰值。</span> </p> <p> 輸入沖擊電流：<span style="font-size:12px;">當接通電源時，交流輸入回路比較大瞬時電流值。</span> </p> <p> <br /> </p> <p> <br /> </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="陜西電源批發(fā)"

對外部的抗干擾能力，對雷擊可采用氧化鋅壓敏電阻與氣體放電管等的組合方法來解決。對于靜電放電，采用TVS管及相應的接地保護，加大小信號電路與機殼等的距離，或選用具有抗靜電干擾的器件來解決。減小電源適配器的內部干擾，應從以下幾個方面入手：注意數字電路與模擬電路單點接地，大電流電路與小電流特別是電流、電壓取樣電路的單點接地，以減小共阻干擾、減小地環(huán)的影響;布線時注意相鄰線間的間距及信號性質，避免產生串擾;減小地線阻抗;減小高壓大電流線路特別是變壓器原邊與開關管、電源濾波電容電路所包圍的面積;減小輸出整流電路及續(xù)流二極管電路與直流濾波電路所包圍的面積;減小變壓器的漏電感、濾波電容的分布電容;采用諧振頻率高的濾波電容器等。 </p> <p> 在傳播途徑方面，適當的增加高抗干擾能力的TUS及高頻電容、鐵氧體磁珠等元器件，以提高小信號電路的抗干擾能力;與機殼距離較近的小信號電路，應加適當的絕緣耐壓處理等;功率器件的散熱器、主變壓器的電磁屏蔽層要適當接地;各控制單元間的大面積接地用接地板屏蔽;在整流器的機架上，要考慮各整流器間電磁耦合、整機地線布置等，以改善電源適配器內部工作的穩(wěn)定性。 </p><div
