The design plans to complete a can provide a stable output of DC regulated power supply. In this paper, the current status of the DC regulated power supply is discussed, and then the difference between different DC regulated power supply is analyzed, and the scheme of the design of DC regulated power supply is demonstrated. Followed by chapter three parts of a DC regulated power supply to achieve design and analysis, discuss each part parameters setting, parameters such as the transistor, rectifier diode parameters, parameters of transformer, filter capacitor parameter and with some were welding and debugging of the whole circuit. The fourth chapter details the process of the production of the circuit and components of the problems encountered, as well as the various problems encountered during the commissioning analysis. In the last fifth chapters, the measurement of the circuit and the output result is carried out, the voltage 12V output is measured, and the output of the 2A current is measured, and the load regulation rate and conversion efficiency are calculated. And summarized in the sixth chapter.. [资料来源：http://doc163.com]
