1、滤波电路及器件选择
整流滤波电路通常有电容、电感和RC等滤波电路。电感滤波是利用电感对脉动电生反电动势，阻碍电流变化来实现的，电感越大，滤波效果越好。它一般用于负载电流大、对滤波要求不高的场台。RC滤波电路是电阻和电容连接使用的滤波电路，由于电阻会降低一部分直流电压，直流输出电压会减小，因此只适用于小电流电路。电容滤波是利用电容的充放电作用使整流输出电压变得平稳，而且电压幅值升高，滤波效果好，适于整流电路。滤波电容的选择主要是种类和容量、耐压值的确定。常用的整流滤波电容有铝电解、钽电解、涤纶、独石电容等。铝电解电容漏电流大，耐压和工作温度(高+70℃)较低，但容量大;钽电解电容漏电流小，耐压和工作温度比铝电解电容都高，一般用于要求较高的地方;涤纶电容绝缘电阻大，损耗小，工作温度(高+55℃)低，容量小，但耐压高;独石电容体积可以做得很小，耐压也可以做得很高，化学性能和热性能比较稳定，但容量小。一般当整流输出电流大时，用电解电容滤波稳压;输出电流小时，用一般电容或电解电容滤波都可以，如果对直流输出电压有纹波系数要求或者为了防止高频噪音，用电解电容和小容量无性电容并联使用效果较好：小容量电容可滤掉脉动直流中的高次谐波，　电解电容滤掉大幅值的低频成分，稳压范围宽、效果好。整流滤波电路对电容器的容量和耐压值要求不是太高，一般根据输出电流大小估算电容器的容量，输出电流大，容量就大;电流小，容量就小。但是，容量太大会降低输出电压值，太小则会导致电压脉动大、不稳定。容量确定可参考表1，耐压值一般取所接电路工作电压的1.5～2倍。
稳压电路及器件选择
稳压电路有分立元件稳压电路和集成稳压电路2种，其中集成稳压电路主要用于低电压小电流的整流电路，具有体积小，电路简单，稳压精度高，使用调试方便等特点。选择时首先要确定系列，是正电源还是负电源，是可调的还是固定的，其次是根据它的额定电压和额定电流选择具体型号;同时，稳压器在接入整流电路时要适当加一些保护元件，如在I/O端接二管可防止输入端短路，在输入端和地之间接一小电容，可限制输入电压幅值等。
直流电源的设计理论上比较简单，但在具体的工程设计中还需要进一步分析、研究、实践和总结。
