V。REM懸空或與+UIN相連，模塊工作，要求UREM>1 V。 REM與UIN相連，關(guān)斷，要求UREM<0．4 V。REM與+UIN相連，模塊工作，要求UREM>l V。REM懸空，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。模塊電源的組合：并聯(lián)擴(kuò)容將相同模塊輸出端并聯(lián)，可使輸出能力增強(qiáng)。但并聯(lián)模塊的輸出電壓要調(diào)整得比較一致，以保證相對均流，同時避免不必要的振蕩。對有較大電流輸出的模塊．還可以仔細(xì)設(shè)計引線電阻，以達(dá)到均流效果。用這種方法并聯(lián)的模塊，不宜超過2個。同時，如果其中一塊模塊輸出有故障，整個系統(tǒng)都將不能正常工作。</p><p style="text-indent:25px">AC/DC變換按電路的接線方式可分為，半波電路、全波電路。按電源相數(shù)可分為，單相、三相、多相。按電路工作象限又可分為一象限、二象限、三象限、四象限。開關(guān)電源的選用開關(guān)電源在輸入抗干擾性能上，由于其自身電路結(jié)構(gòu)的特點(多級串聯(lián))，一般的輸入干擾如浪涌電壓很難通過，在輸出電壓穩(wěn)定度這一技術(shù)指標(biāo)上與線性電源相比具有較大的優(yōu)勢，其輸出電壓穩(wěn)定度可達(dá)(0.5~1)%。開關(guān)電源模塊作為一種電力電子集成器件，在選用中應(yīng)注意以下幾點:因開關(guān)電源工作效率高，一般可達(dá)到80%以上，故在其輸出電流的選擇上，應(yīng)準(zhǔn)確測量或計算用電設(shè)備的較大吸收電流，以使被選用的開關(guān)電源具有高的性能價格比。變頻器電源主電路均采用交流-直流-交流方案。</p><div
