AC-DC開關(guān)電源又被稱為一次電源，是開關(guān)電源的其中一類，AC-DC開關(guān)電源是開關(guān)電源的其中一類，其原理是取得能量后經(jīng)過高壓整流濾波得到一個直流高壓，以供DC-DC變換器在輸出端獲得一個或幾個穩(wěn)定的直流電壓。AC-DC開關(guān)電源的掉電保持時間是其重要的技術(shù)參數(shù)之一，ACDC開關(guān)電源原理，AC輸入經(jīng)過整流濾波后，變成一個直流電壓(有一定的紋波電壓)，再通過DCDC變換器轉(zhuǎn)換成我們所需要的電壓輸出。控制電路可根據(jù)輸入電壓和輸出負載來調(diào)整占空比(PWM模式)以實現(xiàn)穩(wěn)定的電壓輸出。在AC輸入掉電后，由輸入濾波電容存儲的能量給輸出供電，在這個過程中，濾波電容電壓逐漸下降，控制電路通過調(diào)整占空比依然可以實現(xiàn)額定的輸出電壓，直到電容電壓下降到控制電路能調(diào)整的范圍之外時，輸出電壓開始下降。虹口區(qū)ACDC電源模塊價格</p></p><br
