基于MATLAB的整流电路仿真分析

摘要：随着社会生产和科学技术的发展，整流电路在自动控制系统、测量系统和发电机励磁系统等领域的应用日益广泛。常用的整流电路有三相桥式全控整流电路和单相桥式可控电路。由于整流电路涉及到交流信号、直流信号以及触发信号，同时包含晶闸管、电容、电感、电阻等多种元件，采用常规电路分析方法显得相当繁琐，高压情况下实验也难顺利进行。Ｍatlab提供的可视化仿真工具Simulink可直接建立电路仿真模型，随意改变仿真参数，并且立即可得到任意的仿真结果，直观性强，进一步省去了编程的步骤。本文利用Simulink对三相桥式全控整流电路进行建模，对不同控制角、桥故障情况下进行了仿真分析。对单相桥式可控整流电路的相关参数和不同性质负载的工作情况进行对比分析与研究，既进一步加深了三相桥式全控整流电路和单相桥式可控整流电路的理论，同时也为现代电力电子实验教学奠定良好的实验基础。

MATLAB-based simulation analysis of the rectifier circuit

Abstract:With the social production and scientific and technological development, the rectifier circuit in the automatic control system, measurement system and generator excitation system, and other fields increasingly widespread. Commonly used three-phase bridge rectifier circuit with full-controlled single-phase bridge rectifier circuit and control circuit. As the rectifier circuit involves the exchange of signals, DC signals and trigger signals, including thyristors, capacitors, inductors, resistors and other components, using conventional circuit analysis method appeared to be quite complicated, high-pressure situations is difficult to experiments carried out smoothly. Matlab provides a visual simulation tool Simtlink circuit simulation model can be directly set up, free to change simulation parameters and immediately available to any of the simulation results, intuitive, eliminating the need for further programming steps. In this paper, Simulink full control of three-phase bridge rectifier circuit model, for different control angle, the bridge under fault conditions were simulated analysis. Controlled single-phase bridge rectifier circuit parameters and the different nature of the work load of the comparative analysis and research, both to further deepen the three-phase full-controlled bridge rectifier circuit and controlled single-phase bridge rectifier circuit theory, while for modern power electronics experiment experimental teaching lay a good foundation.
