高頻開關(guān)直流電源模塊中所使用的大功率開關(guān)器件價格較貴，其控制電路亦比較復雜，另外，開關(guān)電源的負載一般都是用大量的集成化程度很高的器件安裝的電子系統(tǒng)。晶體管和集成器件耐受電、熱沖擊的能力較差。因而開關(guān)電源模塊的保護應該兼顧其本身和負載的安全。保護電路的種類很多，這里介紹極性保護、程序保護、過電流保護、過電壓保護、欠電壓保護以及過熱保護等電路。通常選用幾種保護方式加以組合，構(gòu)成完善的保護系統(tǒng)。 </p> <p> 2 極性保護 </p> <p> 直流電源模塊開關(guān)穩(wěn)壓器的輸入一般都是未穩(wěn)壓直流電源，由于操作失誤或者意外情況會將其極性接錯，此時將會損壞開關(guān)穩(wěn)壓電源。極性保護的目的就是使開關(guān)穩(wěn)壓器*當以正確的極性接上未穩(wěn)壓直流電源時才能工作。利用單向?qū)ㄆ骷梢詫崿F(xiàn)電源的極性保護。**簡單的極性保護電路如圖1所示。由于二極管D流過開關(guān)穩(wěn)壓器的輸入總電流，因此這種電路應用在小功率的開關(guān)穩(wěn)壓器上比較合適。在較大功率的場合，則把極性保護電路作為程序保護中的一個環(huán)節(jié)，可以省去極性保護所需的大功率二極管，功耗也將減小。為了操作方便，便于識別極性開關(guān)正確與否，在圖1中的二極管之后接指示燈。 </p> <p> <br /> </p><p> 高壓直流電源已越來越***的應用于工業(yè)、醫(yī)學、核物理、檢測等領(lǐng)域。對于X 光機，粒子加速器，電子束焊機，電子束曝光機等一些應用場合，對電壓的水平要求比較高，它們均要求低紋波電壓。文章對幾種用于高壓直流電源的電路拓撲結(jié)構(gòu)分別進行了介紹，并對它們進行了比較，指出了各自的優(yōu)缺點。 </p> <p> 近年來，隨著新的電力電子器件的應用使得高壓直流電源出現(xiàn)了頻率高，效率高，功率密度高，可靠性高等新特性。高頻化可以提高電源性能，減少變壓器的體積和紋波系數(shù)，但也帶來了新的技術(shù)問題。過高的頻率會導致開關(guān)管開斷頻繁，開關(guān)損耗增大，影響開關(guān)管壽命并使整機效率下降。 </p> <p> 鑒于以上問題，本文采用雙路電源并聯(lián)輸出的方法得到低紋波直流。在開關(guān)管頻率受限的***，本方法可以在頻率較低的情況下得到低紋波直流。開關(guān)可調(diào)直流電源價格？</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="湖北可調(diào)直流電源廠商,直流電源" src="https://tyunfile.71360.com/UploadFile/szmdjd/637393089690316908/4897128.png"></div><p> 3、會產(chǎn)生反向電流的負載應用當連接在可編程直流電源供應器輸出端的電機突然剎車時，會產(chǎn)生很大的反向電流，由于可編程直流電源供應器不能吸收從負載端產(chǎn)生的反向電流，因而輸出電壓會上升。解決方法是在可編程直流電源供應器的輸出端與負載之間串聯(lián)一只二極管，并在負載端并接一瀉放電阻來吸收反向電流。當反向電流為一尖峰突波時，請在負載兩端并接一個大容量電解電容。 </p> <p> 4、電容性負載應用因為電容性負載往往會導致輸出電壓升高，尤其在輸出電壓由高向低調(diào)節(jié)時會導致輸出電壓下降緩慢，因此，使用時在可編程直流電源供應器的輸出端并聯(lián)一只功率電阻，并在輸出與負載之間串聯(lián)一只二極管，可獲得較好的使用效果。 </p> <p> 5、脈沖類負載應用脈沖類負載的電流峰值即使在可編程直流電源供應器輸出額定電流值范圍內(nèi)，或者脈沖類電路或電動機驅(qū)動電路負載電流波形，在計量設備所指示的標稱值(平均值)內(nèi)。電流也會達到可編程直流電源供應器額定電流區(qū)域，從而使輸出電壓下降或者顯得不穩(wěn)定。解決方法是在電源供應器與負載之間串接電感器，或者選擇輸出電流更大的可編程直流電源供應器。常用可控直流電源有哪幾種。福建隔離直流電源</p><p
