年代，電源行業(yè)呈式發(fā)展，企業(yè)數量從90 年代初期的幾百家增加到至今的幾萬家，產量從90 年代的十幾億元增加到至今的幾百億元。并還在進一步飛速發(fā)展。電源市場風起云涌，競爭日趨激烈，對于電子工程師，電源似乎已成一個隨處抓一模塊都可以滿足要求的時代。廣東深圳天磁科技有限公司電-源方案</p><div style="width:100%;text-align:

style="font-size:12px;">線性穩(wěn)定電源有一個共同的特點就是它的功率器件調整管工作在線性區(qū)，靠調整管之間的電壓降來穩(wěn)定輸出。由于調整管靜態(tài)損耗大，需要安裝一個很大的散熱器給它散熱。而且由于變壓器工作在工頻（50Hz)上,所以重量較大。</span><span style="font-size:12px;">該類電源優(yōu)點是穩(wěn)定性高，紋波小，可靠性高，易做成多路，輸出連續(xù)可調的成品。缺點是體積大、較笨重、效率相對較低。這類穩(wěn)定電源又有很多種，從輸出性質可分為穩(wěn)壓電源和穩(wěn)流電源及集穩(wěn)壓、穩(wěn)流于一身的穩(wěn)壓穩(wěn)流（雙穩(wěn)）電源。從輸出值來看可分定點輸出電源、波段開關調整式和電位器連續(xù)可調式幾種。從輸出指示上可分指針指示型和數字顯示式型等等。</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>

推挽式電源電流瞬態(tài)響應速度很高，電壓輸出特性很好，在所有拓撲結構中，是利用率比較高的一種開關電源，無漏磁，驅動電路簡單。但其缺點是兩個開關器件需要很高的耐壓值；要有兩組初級線圈，對于小功率輸出的推挽式開關電源是個缺點。若兩個正激式變換器不完全對稱或平衡，經過幾個周期累積的偏磁，會使磁芯進入飽和，導致高頻變壓器勵磁電流過大，甚至損壞開關管。橋式開關電源輸出功率很大，工作效率很高，開關管的耐壓值要求比較低，變壓器初級線圈只需要一個繞組。缺點是效率低，會出現半導通區(qū)，損耗大。以上各種問題都是因為其拓撲結構的先天優(yōu)勢和先天缺點造成的，雖然我們可以將電源模塊當成黑匣子，但這也是我們在選擇電源時要關注的一個點。因為能完成同樣功能的設計方案，一個很輕松地完成，一個要費很大的勁才能完成。廣東深圳天磁科技有限公司電-源方案</p></p><br
