1、濾波電路及器件選擇
整流濾波電路通常有電容、電感和RC等濾波電路。電感濾波是利用電感對脈動電生反電動勢，阻礙電流變化來實現(xiàn)的，電感越大，濾波效果越好。它一般用于負載電流大、對濾波要求不高的場臺。RC濾波電路是電阻和電容連接使用的濾波電路，由于電阻會降低一部分直流電壓，直流輸出電壓會減小，因此只適用于小電流電路。電容濾波是利用電容的充放電作用使整流輸出電壓變得平穩(wěn)，而且電壓幅值升高，濾波效果好，適于整流電路。濾波電容的選擇主要是種類和容量、耐壓值的確定。常用的整流濾波電容有鋁電解、鉭電解、滌綸、獨石電容等。鋁電解電容漏電流大，耐壓和工作溫度(高+70℃)較低，但容量大;鉭電解電容漏電流小，耐壓和工作溫度比鋁電解電容都高，一般用于要求較高的地方;滌綸電容絕緣電阻大，損耗小，工作溫度(高+55℃)低，容量小，但耐壓高;獨石電容體積可以做得很小，耐壓也可以做得很高，化學性能和熱性能比較穩(wěn)定，但容量小。一般當整流輸出電流大時，用電解電容濾波穩(wěn)壓;輸出電流小時，用一般電容或電解電容濾波都可以，如果對直流輸出電壓有紋波系數(shù)要求或者為了防止高頻噪音，用電解電容和小容量無性電容并聯(lián)使用效果較好：小容量電容可濾掉脈動直流中的高次諧波，　電解電容濾掉大幅值的低頻成分，穩(wěn)壓范圍寬、效果好。整流濾波電路對電容器的容量和耐壓值要求不是太高，一般根據(jù)輸出電流大小估算電容器的容量，輸出電流大，容量就大;電流小，容量就小。但是，容量太大會降低輸出電壓值，太小則會導致電壓脈動大、不穩(wěn)定。容量確定可參考表1，耐壓值一般取所接電路工作電壓的1.5～2倍。
穩(wěn)壓電路及器件選擇
穩(wěn)壓電路有分立元件穩(wěn)壓電路和集成穩(wěn)壓電路2種，其中集成穩(wěn)壓電路主要用于低電壓小電流的整流電路，具有體積小，電路簡單，穩(wěn)壓精度高，使用調(diào)試方便等特點。選擇時首先要確定系列，是正電源還是負電源，是可調(diào)的還是固定的，其次是根據(jù)它的額定電壓和額定電流選擇具體型號;同時，穩(wěn)壓器在接入整流電路時要適當加一些保護元件，如在I/O端接二管可防止輸入端短路，在輸入端和地之間接一小電容，可限制輸入電壓幅值等。
直流電源的設計理論上比較簡單，但在具體的工程設計中還需要進一步分析、研究、實踐和總結(jié)。
