style="font-size:12px;">該類電源優(yōu)點(diǎn)是穩(wěn)定性高，紋波小，可靠性高，易做成多路，輸出連續(xù)可調(diào)的成品。缺點(diǎn)是體積大、較笨重、效率相對較低。這類穩(wěn)定電源又有很多種，從輸出性質(zhì)可分為穩(wěn)壓電源和穩(wěn)流電源及集穩(wěn)壓、穩(wěn)流于一身的穩(wěn)壓穩(wěn)流（雙穩(wěn)）電源。從輸出值來看可分定點(diǎn)輸出電源、波段開關(guān)調(diào)整式和電位器連續(xù)可調(diào)式幾種。從輸出指示上可分指針指示型和數(shù)字顯示式型等等。</span>

style="font-size:12px;">負(fù)載的類型也是一個(gè)影響因素。一般的模塊，其輸出是按照默認(rèn)為阻性負(fù)載而設(shè)計(jì)的，如果負(fù)載是感性或容性負(fù)載，都需要與模塊廠家單獨(dú)說明，以便廠家出廠時(shí)的電源模塊內(nèi)部器件或參數(shù)稍作調(diào)整。</span><span
