1)限制示波器帶寬為20MHz(大多中低端示波器檔位限制在20MHz，優(yōu)良產(chǎn)品還有200MHz帶寬限制的選擇)，目的是避免數(shù)字電路的高頻噪聲影響紋波測量，盡量保證測量的準確性。 2)設(shè)置耦合方式為交流耦合，方便測量(以更小檔位來仔細觀測紋波，不關(guān)心直流電平)。 3)保證探頭接地盡量短(測量紋波動輒上百mV的主要原因就是接地線太長)，盡量使用探頭自帶的原裝測試短針。如果沒有測試短針，可以拆除探頭的接地線和外殼，露出探頭地殼，自制接地線纏繞在探頭地殼上，保證接地線長度小于1cm。 </p><p style="text-indent:25px">電源模塊出現(xiàn)燒毀的情況其實是常見的，電源模塊在長期使用下，會出現(xiàn)故障是不可避免的。電網(wǎng)的電壓太高，或者是震動高頻，又或者是溫度太高，也有可能是元器件因為接觸不良導致的。AC/DC電源管理模塊進行輸入的交流電壓過高或過低；開關(guān)電壓器損壞；整流橋損壞；軟啟動電路失效；開關(guān)電路板反峰吸收電路故障;正反饋過強；定時進行電容控制失效漏電；穩(wěn)壓電路失耦電容；穩(wěn)壓模塊電路的負反饋系統(tǒng)開環(huán)；限位開關(guān)發(fā)射極電阻太小;開關(guān)管性能產(chǎn)生不良或功率太?。徽鞫O管被破壞;輸入輸出反接；電解電容炸裂。開關(guān)電源模塊作為一種電力電子集成器件。</p><div

(DSP)、微處理器、存儲器、現(xiàn)場可編程門陣列 (FPGA) 及其他數(shù)字或模擬負載提供供電。一般來說，這類模塊稱為負載點 (POL) 電源供應(yīng)系統(tǒng)或使用點電源供應(yīng)系統(tǒng) (PUPS)。由于模塊式結(jié)構(gòu)的優(yōu)點甚多，因此模塊電源普遍用于交換設(shè)備、接入設(shè)備、移動通訊、微波通訊以及光傳輸、路由器等通信領(lǐng)域和汽車電子、航空航天等。近幾年由于數(shù)據(jù)業(yè)務(wù)的飛速發(fā)展和分布式供電系統(tǒng)的不斷推廣,模塊電源的增幅已經(jīng)超出了一次電源。模塊電源具有隔離作用，抗干擾能力強，自帶保護功能，便于集成。隨著半導體工藝、封裝技術(shù)和高頻軟開關(guān)的大量使用,模塊電源功率密度越來越大,轉(zhuǎn)換效率越來越高,應(yīng)用也越來越簡單。人們在開關(guān)電源技術(shù)領(lǐng)域是邊開發(fā)相關(guān)的電力電子器件，邊開發(fā)開關(guān)變頻技術(shù)，兩者相互促進推動著開關(guān)電源每年以超過兩位數(shù)字的增長率向著輕、小、薄、低噪聲、高可靠、抗干擾的方向發(fā)展。一般可以通過在輸入端選擇合適的保險管進行保護。天津DCDC電源模塊咨詢</p><p

style="text-indent:25px">合理安裝減小機械應(yīng)力，模塊電源的引出方式均為金屬針，模塊電源與外接線路、金屬針與模塊電源內(nèi)路電路均采用焊接方式連接。在一些特殊場合機械振動強度較大，尢其是大功率模塊電源上還要加裝散熱器，這種情況更為嚴重。雖然模塊電源內(nèi)部一般灌封導熱絕緣橡膠可以對元件起到較好的緩沖保護作用，但焊點有可能經(jīng)受不住強烈振動應(yīng)力而斷裂，導致模塊電源工作失效，這時必須在焊接的基礎(chǔ)上再采取另外的固定和緩沖措施，比如可以用夾具或螺栓（對于有螺孔模塊）將模塊與機箱、大線路板等相對抗振性能好的部件固定，并且在它們中間墊一些彈性材料以緩沖振動產(chǎn)生的應(yīng)力。總之，模塊電源和其它元器件一樣只有精心選擇、合理應(yīng)用才能使其性能得到較大發(fā)揮，可靠性得到充分保障，模塊電源也才會被更普遍地采用。天津DCDC電源模塊咨詢</p></p><br
