走線阻抗大。電源模塊輸出與負(fù)載連接必然要有一段PCB走線，走線越長(zhǎng)、走線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，除了走線問題還有很多情況起到類似的作用，路燈電-源廠家供應(yīng)，比如焊點(diǎn)接觸不良導(dǎo)致等效電阻增加，線路氧化或腐蝕導(dǎo)致等效電阻增加。<span

推挽式電源電流瞬態(tài)響應(yīng)速度很高，電壓輸出特性很好，在所有拓?fù)浣Y(jié)構(gòu)中，是利用率比較高的一種開關(guān)電源，無漏磁，驅(qū)動(dòng)電路簡(jiǎn)單。但其缺點(diǎn)是兩個(gè)開關(guān)器件需要很高的耐壓值；要有兩組初級(jí)線圈，對(duì)于小功率輸出的推挽式開關(guān)電源是個(gè)缺點(diǎn)。若兩個(gè)正激式變換器不完全對(duì)稱或平衡，經(jīng)過幾個(gè)周期累積的偏磁，會(huì)使磁芯進(jìn)入飽和，導(dǎo)致高頻變壓器勵(lì)磁電流過大，甚至損壞開關(guān)管。橋式開關(guān)電源輸出功率很大，工作效率很高，開關(guān)管的耐壓值要求比較低，變壓器初級(jí)線圈只需要一個(gè)繞組。缺點(diǎn)是效率低，會(huì)出現(xiàn)半導(dǎo)通區(qū)，損耗大。以上各種問題都是因?yàn)槠渫負(fù)浣Y(jié)構(gòu)的先天優(yōu)勢(shì)和先天缺點(diǎn)造成的，雖然我們可以將電源模塊當(dāng)成黑匣子，但這也是我們?cè)谶x擇電源時(shí)要關(guān)注的一個(gè)點(diǎn)。因?yàn)槟芡瓿赏瑯庸δ艿脑O(shè)計(jì)方案，一個(gè)很輕松地完成，一個(gè)要費(fèi)很大的勁才能完成。智慧電源具備電源轉(zhuǎn)換、數(shù)據(jù)采集、計(jì)量檢測(cè)等功能。北京智能燈桿電-源廠家供應(yīng)</p><p
