Abstract:We make the DC stabilized power supply as the core of the system,and SCM STC12C5A60S2 as the main controller.The output voltage of direct supply through can be set at the keyboard in a step-by-step class of 0.1V and the output voltage range from 100 to 250,with the maximum current of 2A,and display the actual output through the Nixie tube.
In this system,SCM output the digital signal to D/A translator（DAC0832）,then it output analog quantity to the operational amplifier for isolating and enlarging which use to control the base of output power pipe.It outputting different voltage with the change of the voltage of the base. Actual test show this system can be use in the field of miniwatt constant-voltage source with high stability.
Keywords:DC stabilized power supply,SCM STC12C5A60S2,D/A translator（DAC0832）.
做课题啊，专业性的东西，最好自己查相关资料翻译，以后会接触很多英文的资料，现在开始积累吧。帮你翻译反而害了你。。。
