正激電源輸出電壓瞬態(tài)控制特性較好，負載能力較強，但其缺點也同樣，多用一個大儲能濾波電感和一個續(xù)流二極管、體積大、變壓器初級線圈反電動勢電壓高，對開關(guān)管的要求較高。<span

隨著5G基站使用高頻通信、支撐大容量高速度的需求，大量的微小基站來完成更密集的網(wǎng)絡(luò)涵蓋將成為5G時代亟待解決的問題。無論從高度、間距，還是從電源配套等角度考慮，燈桿似乎都是5G小基站的推薦搭配。<span

</p><p> “這部分電路到底需不需要隔離？”這基本上是每一個嵌入式系統(tǒng)工程師都會思考的問題。<span style="font-size:12px;">從隔離的目的來說，可以將隔離分為安全隔離和噪聲隔離兩大類。由于嵌入式系統(tǒng)的應(yīng)用廣</span><span

電源模塊輸出有電壓但電壓低于標(biāo)稱輸出值是測試過程中經(jīng)常遇到的問題，出現(xiàn)這種情況的原因無非有兩種，一是電源模塊為不良品或損壞，二是使用方法問題。下文天磁將重點討論使用方法導(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)輸出有問題時我們應(yīng)該檢查輸入是否正常。對于輸入為定壓或?qū)拤旱碾娫茨K，當(dāng)輸入值偏低時將導(dǎo)致輸出值也偏低。當(dāng)然，這種情況是有限度的，對于一個特定的模塊來說，當(dāng)輸入電壓過低時將導(dǎo)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(dāng)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(dǎo)致模塊使用壽命減少。若是過載導(dǎo)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> </p> <p> <br /> 電源控制器_電源時序控制_專業(yè)智能用電設(shè)備提供商。北京智慧路燈電-源***選擇</p><p style="text-indent:25px">電源市場風(fēng)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。廣東智能路燈電-源品牌好嗎</p><p> 紋波與拓撲結(jié)構(gòu)、電容電感的參數(shù)、負載的情況都相關(guān)，一個5v電源，紋波做到50mv，單電源的誤差就是1%了，對精度要求高的電路，電源的誤差、放大電路的誤差、信號電纜的誤差、AD的舍入誤差，多個誤差累積合并之后，總誤差可就大了。電<span style="font-size:12px;">源模塊里有無濾波設(shè)計、電源模塊所在的設(shè)備里有無安規(guī)要求（漏電流、絕緣耐壓、濕度要求）、溫升特性、轉(zhuǎn)換效率、輸入電壓的波動范圍、負載調(diào)整率等等，要求的地方還是不少的。</span><span style="font-size:12px;">天磁覺得電子產(chǎn)品的電源模塊選擇，不是只有成本這個指標(biāo)值得被關(guān)注。</span> </p> <p> <br /> 廣東智能路燈電-源品牌好嗎</p></p><br /><p>文章來源地址:
