摘要当下整流电路的品种繁多，主要有单相桥式可控电路和三相全控桥电路。整流电路信号涉及复杂，同时包含各种电力电子元件，如果以常规的电路分析方法显得十分困难，甚至某些条件如高压条件下的分析也难以进行。通过Matlab等仿真软件的优越特性和经济效益，必将成为此后人们所着重和加大力度研究的项目。将仿真软件系统运用到人类自然生活工作的过程中，这样才能有效的避免一些决策上失误，能够通过仿真波形观察到可能潜在的风险，便能够实现避免故障和规避危害的目地。Matlab中的仿真模块Simulink可设立仿真电路模型，根据需要设置器件参数，并可以很快得到仿真波形开始分析。本文介绍了通过Simulink对单相和三相整流电路仿真，并在各种触发角以及各种负载的仿真结果下进行了研究分析。验证了整流电路的输出电压受触发角α和所带负载特性的关系。本文既帮助加深了自身对相关工作原理的理解，也为现代电子技术仿真实验教研奠定优良的基础。77285

Abstract With the progress of the times and the science , the requirements of electronic devices on the rectifier circuti is also increased today, 。So it is very important to expand the input power of the rectifier circuit, improve the stability of the output voltage, and improve the performance of the circuit。 Therefore, the rectifier circuit at home and abroad are expected to ensure that the output voltage is high and can be regulated under the premise。 For this problem, many experts and workers at home and abroad to do a lot of improvements to the rectifier circuit, and also to get a good effect。 For example, some experts use the thyristor to replace the conventional diode output voltage adjustable。 Now some of the world's developed countries in the field of power electronics technology has been very mature。 And they invented the Cuck, buck, boost and other circuits have been incorporated into a variety of national teaching books in the literature。 Current rectifier circuit has a single phase bridge controlled circuit and three-phase fully controlled bridge circuit。 Rectifier circuit signal involves complex, and contains a variety of power electronic components, if the conventional circuit analysis method is very difficult, and even some conditions such as high pressure is also difficult to carry out。 Matlab simulation module Simulink can establish the simulation circuit model, set the simulation parameters, and can quickly get the results of the analysis,。 In this paper, the modeling and Simulation of single phase and three phase rectifier circuit with Simulink are analyzed, and the different trigger angles and different load cases are analyzed。 Deepen their own understanding of the relevant knowledge, but also for the modern power electronics experimental teaching lay a good foundation for the experiment。
Key words: three phase bridge rectifier circuit, single phase bridge half controlled rectifier, single phase bridge rectifier, Simulink modeling, simulation analysis
