摘　　要：本文首先叙述了模拟电压阶跃仪应用的背景及创新点，提出了基于555定时器的电压阶跃电路，介绍了电路的工作原理，同时结合实际介绍了具体的设计过程。最后通过实验证明，本电压阶跃电路电压跃变时间短，电压过冲和跌落小，具有替代模拟干扰仪的作用。同时体积小、重量轻，使用方便。This paper firstly introduces the application background of analogue voltage step instrument, then a voltage step circuit based on 555 timer is proposed. At the same time, the specific design process is introduced in combination with the actual situation. Finally, it is proved by experiments that the voltage step circuit has short voltage transition time, small voltage overshoot and small drop, and has the function of replacing the analog interferometer. The circuit is small in size, light in weight and easy to use.
