走線(xiàn)阻抗大。電源模塊輸出與負(fù)載連接必然要有一段PCB走線(xiàn)，走線(xiàn)越長(zhǎng)、走線(xiàn)越窄則它的等效電阻越大。等效電阻可以認(rèn)為是串聯(lián)在負(fù)載的工作回路中，將起到分壓作用，因此導(dǎo)致負(fù)載兩端的電壓小于模塊的輸出電壓。此外，除了走線(xiàn)問(wèn)題還有很多情況起到類(lèi)似的作用，比如焊點(diǎn)接觸不良導(dǎo)致等效電阻增加，線(xiàn)路氧化或腐蝕導(dǎo)致等效電阻增加。<span style="font-size:12px;">防反接二極管。很多產(chǎn)品的AC和DC部分是不在一塊板上的，在生產(chǎn)或終端客戶(hù)使用中不可避免涉及到插拔電源連接器的情況。為防止此過(guò)程中的反接導(dǎo)致的硬件損壞，常串入一只二極管解決。以壓降0.7V的二極管為例，b1 b2間的電壓將比a1 a2間電壓小0.7V，這也就是上面所討論的輸入電壓偏低的情況，可以通過(guò)選擇壓降低的管子或者直接提高a1 a1間電壓的方法解決。</span> </p> <p> 路燈電-源哪家好智能電源是基于SPM云端智能管理系統(tǒng)，進(jìn)而開(kāi)發(fā)的軟件平臺(tái)，是硬件和軟件的結(jié)合體</p><div style="width:100%;text-align:

電源模塊輸出有電壓但電壓低于標(biāo)稱(chēng)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>
