style="text-indent:25px">一般大功率電源模塊產(chǎn)品都有內(nèi)置濾波器，能滿足一般電源應(yīng)用的要求。如果需要更高要求的電源系統(tǒng)，應(yīng)增加輸入濾波網(wǎng)絡(luò)。可以采用LC或π型網(wǎng)絡(luò)，但應(yīng)注意盡量選擇較小的電感和較大的電容。為了防止輸入電源瞬態(tài)高壓損壞電源模塊，建議用戶在輸入端接瞬態(tài)吸收二極管并配合保險(xiǎn)絲使用，以確保電源模塊在安全的輸入電壓范圍之內(nèi)。為了降低共模噪聲，可以增加Y(Cy)電容，一般選擇幾nf高頻電容。R為保險(xiǎn)絲，D1為保護(hù)二極管，D2為瞬態(tài)吸收二極管(P6KE系列)。電源模塊的遙控開關(guān)操作，是通過REM端進(jìn)行的。一般控制方式有兩種：REM與VIN相連，遙控關(guān)斷，要求VREM<0.4V。REM與+VIN相連，模塊工作，要求VREM>1V。REM懸空，遙控關(guān)斷，即所謂“懸空關(guān)斷”(-R)。如果控制要與輸入端隔離，則可以使用光電耦合器作為傳遞控制信號(hào)。</p><p
