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> 上海燈桿電-源供應(yīng)商家基于OneNET協(xié)議兼容特性，實(shí)現(xiàn)不同廠家的設(shè)備協(xié)議兼容和互通。</p><div style="width:100%;text-align:
