摘 要

本次课程设计题目要求为三相PWM逆变器的设计。设计过程从原理分析、元器件的选取,到方案的确定以及Matlab仿真等,巩固了理论知识,基本达到设计要求。

本文将按照设计思路对过程进行剖析,并进行相应的原理讲解,包括逆变电路的理论基础以及Matlab仿真软件的简介、运用等,此外,还会清晰的介绍各个环节的设计,比如触发电路、控制电路、主电路等,其中部分电路的绘制采用Proteus软件,最后结合Matlab Simulink仿真,建立了三相全控桥式电压源型逆变电路的仿真模型,进而通过软件得到较为理想的实验结果。

Abstract

The curriculum design subject requirements for the design of the three-phase PWM inverter. Design process from the principle of analysis, selection of components, to scheme and the Mat-lab simulation, etc., to consolidate the theoretical knowledge, basic meet the design requirements.

This article will be carried out in accordance with the design of process analysis, and the corresponding principles, including the theoretical foundation of the inverter circuit and introduction, using Matlab simulation software, etc., in addition, will also clearly introduces the design of every link, such as trigger circuit, control circuit, main circuit, etc., some of the drawing of the circuit using Proteus software, finally combined with Matlab Simulink, established a three-phase fully-controlled bridge voltage source type inverter circuit simulation model, and then through the software to get the ideal results.

Keywords: Matlab simulation, three-phase ,PWM, inverter circuit
