摘　　要：直流稳压电源可以将交流电压变换为直流电压,并使之稳定,在我们现实生活中应用很广泛,在实验中我们利用的电学知识,设计制造了一种直流稳压电源。本文简要介绍了这种直流稳压电源波形演示器的设计目的和电路原理,重点阐述了它的制作流程、滤波和稳压原理以及性能测试输出波形。The direct current voltage- stabilized source, which changes alternating current into direct current and makes it steady, applies widely in our actual life. We use the electricity knowledge to design and make a direct current voltage - stabilized source in our experiment. In this paper we introduce the purpose and the electric circuit of this design, the process of its making, the way of filtering, the way of making voltage steady, and the way of testing the output wave.
