style="text-indent:25px">開(kāi)關(guān)電源的工作模式有三種：頻率、脈沖寬度固定模式，多用于DC/AC逆變電源，或者DC/DC電壓變換。頻率固定、脈沖寬度可變模式，多用于開(kāi)關(guān)穩(wěn)壓電源。頻率、脈沖寬度可變模式，多用于開(kāi)關(guān)穩(wěn)壓電源。開(kāi)關(guān)電源輸出電壓也有三種工作方式：直接輸出電壓方式，多用于DC/AC逆變電源，或DC/DC電壓變換。平均值輸出電壓方式，多用于開(kāi)關(guān)穩(wěn)壓電源。幅值輸出電壓方式，多用于開(kāi)關(guān)穩(wěn)壓電源。造成輸入電壓過(guò)高的原因有三種，分別是：輸出端懸空或無(wú)負(fù)載；輸出端負(fù)載過(guò)輕，輕于10%的額定負(fù)載；輸入電壓偏高或干擾電壓。可以通過(guò)調(diào)整輸出端的負(fù)載或調(diào)整輸入電壓范圍，確保輸出端不小于少10%的額定負(fù)載，若實(shí)際電路工作中會(huì)有空載現(xiàn)象，就在輸出端并接一個(gè)額定功率10%的假負(fù)載。更換一個(gè)合理范圍的輸入電壓，存在干擾電壓時(shí)要考慮在輸入端并上TVS管或穩(wěn)壓管。一般模塊電源有較小負(fù)荷限制。山東ACDC電源模塊公司</p><p
