Simulation of three-phase SPWM inverter based on Matlab/Simulink

简单介绍了三相SPWM逆变器的组成和工作原理,通过计算机对三相SPWM逆变器进行Matlab/Simulink建模和仿真,研究逆变电路的输入输出及其特性。仿真分析经逆变后得到的电压电流的特性。通过运用Matlab/Simulink和Power System Block(PSB)电力系统模块集工具箱仿真环境,对电路进行建模、计算和仿真分析。MATLAB软件中的Simulink,是为数不多的完全满足这些条件和要求的软件。并且凭借他在科学计算方面的天然优势建立了从设计构思到最终实现设计要求的可视化桥梁。被广泛应用于线性系统、非线性系统及数字信号处理的建模和仿真中。

This paper briefly described the working principle of the three-phase SPWM inverter by the simulation of three- phase SPWM inverter. Described the input and output characters. Analysised the characters of the voltage and current through the inverter. Through the use of Maflab / Simulink and Power System Block （PSB） power system blockset Toolbox simulation environment, analysis circuit modeling calculation and simulation . MATLAB Simulink software is one of the few fully meet these conditions and requirements of the software. And is the visual bridge from design concept to final design requirements established by virtue of his natural advantages in scientific computing .It is widely used in linear and nonlinear systems, in digital control and digital signal processing.
