摘　　要：整流滤波稳压电路是电工学模拟电子学中的重要组成部分,该教学内容概率与参数多、波形复杂、各个知识点分散,不便于掌握。为此,文中设计一种基于Multisim 14的单相整流滤波稳压电路。该电路无需添加或删除元器件,通过控制开关的闭合即可分别实现单相半波全波整流、整流滤波、整流滤波稳压电路及各种接线故障的模拟分析。通过对各种仿真电路进行仿真,给出详细的仿真波形和参数;并将仿真结果与理论及经验计算公式、二极管选择依据进行比较,对相关电路中的重点难点进行阐述。该仿真电路将各个知识点串成一条线,可以极大地帮助学生加深对相关概念参数与波形的理解,并克服现场实验时示波器不能同时观看输入和输出波形与无法实现接线故障实验的缺点。The rectifier-filtering voltage stabilizing circuit is an important part of the analog electronics in electrical engineering.The teaching content contains many probabilities,parameters,complex waveforms and scattered knowledge points,which is not easy to master.A single-phase rectifier-filtering voltage stabilizing circuit based on Multisim 14 is designed.Without adding or deleting components,the circuit can realize the simulation analysis of single-phase half-wave and full wave rectification,rectifier filtering,rectifier filtering voltage stabilizing circuit and various wiring faults respectively by controlling the on/off of the switch.Various simulation circuits are simulated,detailed simulation waveforms and parameters are given,the simulation results are compared with theoretical and empirical calculation formulas and diode selection basis,and the key and difficult points in the related circuits are explained.The simulation circuit can string various knowledge points into a line,which can greatly help students deepen their understanding of related conceptual parameters and waveforms,and improve the disadvantages that the input and output waveforms cannot be observed on the oscilloscope at the same time and the wiring fault cannot be realized in experiment.
