Summary:First of all,the program argues that the design of appropriate programs,there are two options,the program I:Series DC Power Supply,Option II:Integrated circuit voltage regulator.Taking into account the practical problems,one of our options using the steady flow mode power operational amplifier,schematic diagram shown in Figure 1.Comparison of the program,the program after the demonstration schematic qualitative analysis,quantitative estimate of the experimental adjustments to the schematic diagram of the unit parameters and calculate the rectifier filter circuit parameters,the various components in accordance with the appropriate parameter values of selected components,are listed in the list of components .
Key words:qualitative and quantitative schematic block diagram adjustment
