電源模塊輸出有電壓但電壓低于標(biāo)稱輸出值是測(cè)試過(guò)程中經(jīng)常遇到的問(wèn)題，出現(xiàn)這種情況的原因無(wú)非有兩種，一是電源模塊為不良品或損壞，二是使用方法問(wèn)題。下文天磁將重點(diǎn)討論使用方法導(dǎo)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(dāng)輸出有問(wèn)題時(shí)我們應(yīng)該檢查輸入是否正常。對(duì)于輸入為定壓或?qū)拤旱碾娫茨K，當(dāng)輸入值偏低時(shí)將導(dǎo)致輸出值也偏低。當(dāng)然，這種情況是有限度的，對(duì)于一個(gè)特定的模塊來(lái)說(shuō)，當(dāng)輸入電壓過(guò)低時(shí)將導(dǎo)致其不能工作，無(wú)輸出電壓。</span><span style="font-size:12px;">輸出過(guò)載是指負(fù)載工作功率大于電源模塊的額定輸出功率，過(guò)載情況下電源模塊的輸出電壓明顯被拉低。以ZY0505FS-1W為例，當(dāng)負(fù)載電流增大到300mA時(shí)，輸出電壓只有4.5V。持續(xù)過(guò)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(dǎo)致模塊使用壽命減少。若是過(guò)載導(dǎo)致的輸出電壓過(guò)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">性能”和“成本”是一對(duì)相愛相殺的冤家，讓多少工程師面臨兩難的選擇，多少辛辛苦苦做的方案，由于成本問(wèn)題不得不放棄。是為了性能不顧成本？還是為了成本**性能？怎樣平衡性能和成本，這是在產(chǎn)品設(shè)計(jì)中亙古不變的話題。對(duì)于同樣輸入輸出電壓的DC/DC電源模塊來(lái)說(shuō)，輸出功率和工作溫度范圍是影響其成本的主要因素。電子器件工作溫度范圍一般分為：商業(yè)級(jí)（0~70℃）、工業(yè)級(jí)（-40~85℃）、車規(guī)級(jí)（-40~105℃）、**級(jí)（-55~125℃）等。由于溫度等級(jí)不同，對(duì)材料和制造工藝的要求不同，模塊成本就相差很大了。</p><p style="text-indent:25px">負(fù)載的類型也是一個(gè)影響因素。一般的模塊，其輸出是按照默認(rèn)為阻性負(fù)載而設(shè)計(jì)的，如果負(fù)載是感性或容性負(fù)載，都需要做電源模塊內(nèi)部器件或參數(shù)稍作調(diào)整。電源模塊的開關(guān)頻率也是需要關(guān)注的，他決定了外接電源濾波器濾波參數(shù)(截止頻率、階次)的選擇。紋波與拓?fù)浣Y(jié)構(gòu)、電容電感的參數(shù)、負(fù)載的情況都相關(guān)，一個(gè)5v電源，紋波做到50mv，單電源的誤差就是1%了，對(duì)精度要求高的電路，電源的誤差、放大電路的誤差、信號(hào)電纜的誤差、AD的舍入誤差，多個(gè)誤差累積合并之后，總誤差可就大了。電源模塊里有無(wú)濾波設(shè)計(jì)、電源模塊所在的設(shè)備里有無(wú)安規(guī)要求(漏電流、絕緣耐壓、濕度要求)、溫升特性、轉(zhuǎn)換效率、輸入電壓的波動(dòng)范圍、負(fù)載調(diào)整率等等，要求的地方還是不少的。電源就是把其他形式的能量轉(zhuǎn)化成電能的裝置。</p><div
