min之內(nèi)，均不可觸及高壓危險區(qū)。模塊電源選型原則：一般功率較大的宜選擇開關(guān)電源，功率較小的選擇線性電源。模塊電源一般極少損壞，當(dāng)高壓電源工作異常時如加不上電，關(guān)閉供電，檢查安裝在高壓電源內(nèi)的模塊電源輸出輸入端是否斷路或短路，如有這些現(xiàn)象即說明模塊電源損壞，更換模塊電源即可。模塊電源通常由廠家一次性封裝。不可強行拆卸。開關(guān)電源的基本構(gòu)成，其中DC-DC變換器用于進(jìn)行功率轉(zhuǎn)換，他是開關(guān)電源的重要部分，此外還有啟動、過流和過壓保護(hù)、噪聲濾波等電路。輸出采樣電路(R1、R2)檢測輸出電壓的變化，并與基準(zhǔn)電壓Ur比較，誤差電壓經(jīng)過放大及脈寬調(diào)制電路(PWM),在經(jīng)過驅(qū)動電路控制功率器件的占空比，從而達(dá)到調(diào)整輸出電壓大小的目的。一般功率較大的宜選擇開關(guān)電源，功率較小的選擇線性電源。</p><div

style="text-indent:25px">模組電源的輸出端采用的是接口系統(tǒng)設(shè)計，而非模組則是通過直接從內(nèi)部可以引出的供電線；在耗損方面，模組電源的連接點更多資源損耗要求更高，非模組的供電線沒有直接從PCB引出，損耗成本更低。模組電源和非模組的不同地方在外觀方面。模組電源被替換為一個模塊接口板，PCB板引出到連接至輸出接口模塊板的電源線;非模組進(jìn)行電源是從內(nèi)部問題引出一大堆供電線的，它們是直接從PCB板上引出；模塊電源的PC B板與連接主機(jī)的供電線路之間有兩個連接點。將PC B板接入模塊接口，模塊接口接入供電線路，模塊供電效率略低于非模塊供電；由于非模塊電源的 pcb 與電源線之間只有一個連接點，損耗很低。虹口區(qū)DCDC電源模塊咨詢</p><p
