基于S函数的三电平逆变器SVPWM调制的仿真实现

Simulation on the SVPWM Modulation Strategy for the Three-level Inverter Based on S-Function

在分析逆变器空间矢量SVPWM调制原理的基础上,利用Matlab/SimulinkS函数及仿真程序对这种调制方式进行仿真。从仿真波形可以得出利用S函数仿真得到的SVPWM调制结果与直接利用Simulink建模得到的响应是完全一致的,论证了仿真模型的方便性与有效性。

This paper used Matlab/Simulink S-Function and simulation to simulate SVPWM based on theory analysis of SVPWM modulation strategy. The waves of simulation demonstrated that there was no difference between the results modulated by S-Function and those by using Simulink modules directly. Also, it has been proved the simplicity and correctness of using S-Function to simulate this modulation strategy.
