LED驅(qū)動電源的輸入包括高壓工頻交流(即市電)、低壓直流、高壓直流、低壓高頻交流(如電子變壓器的輸出)等。

關(guān)鍵字： 驅(qū)動電源

在工業(yè)自動化蓬勃發(fā)展的當(dāng)下，工業(yè)電機作為核心動力設(shè)備，其驅(qū)動電源的性能直接關(guān)系到整個系統(tǒng)的穩(wěn)定性和可靠性。其中，反電動勢抑制與過流保護(hù)是驅(qū)動電源設(shè)計中至關(guān)重要的兩個環(huán)節(jié)，集成化方案的設(shè)計成為提升電機驅(qū)動性能的關(guān)鍵。

關(guān)鍵字： 工業(yè)電機 驅(qū)動電源

LED 驅(qū)動電源作為 LED 照明系統(tǒng)的 “心臟”，其穩(wěn)定性直接決定了整個照明設(shè)備的使用壽命。然而，在實際應(yīng)用中，LED 驅(qū)動電源易損壞的問題卻十分常見，不僅增加了維護(hù)成本，還影響了用戶體驗。要解決這一問題，需從設(shè)計、生...

關(guān)鍵字： 驅(qū)動電源 照明系統(tǒng) 散熱

根據(jù)LED驅(qū)動電源的公式，電感內(nèi)電流波動大小和電感值成反比，輸出紋波和輸出電容值成反比。所以加大電感值和輸出電容值可以減小紋波。

電動汽車(EV)作為新能源汽車的重要代表，正逐漸成為全球汽車產(chǎn)業(yè)的重要發(fā)展方向。電動汽車的核心技術(shù)之一是電機驅(qū)動控制系統(tǒng)，而絕緣柵雙極型晶體管(IGBT)作為電機驅(qū)動系統(tǒng)中的關(guān)鍵元件，其性能直接影響到電動汽車的動力性能和...
