摘要

本文对多电平逆变器的开关技术进行了谐波注入与非谐波注入的对比分析。多电平逆变器被认为是一种功率变换器系统，其中通过适当地控制功率半导体源将产生可控的多阶电压波形。第一种方法是在Simulink中采用无谐波注入的sink实现多电平逆变器。第二种方法是在多电平逆变器中注入谐波。在输出电压质量提高和总谐波降低的基础上，对两者进行了比较。本文旨在扩展有关谐波分析性能的成熟知识。利用MATLAB/Simulink对谐波注入法和无谐波注入法进行了仿真。

A comparative analysis on multilevel inverter with and without harmonics injection method

In this paper, a comparative analysis of with and without injecting the harmonics in switching techniques for multilevel inverter was carried out. The multilevel inverter are said to be the power converter systems where the by controlling the power semiconductor sources properly a controlled multistep voltage waveform will generate. The first approach on multilevel inverter is carried out in Simulink by taking the sink without harmonics injection. The second approach injecting the harmonics in the multilevel inverter. These both are compared on the basis of their quality improve in output voltage and also the total harmonic reduction. This paper aims to extend the well developed knowledge about the performance of harmonic analysis. Simulation result for with and without harmonic injection method was carried out using MATLAB/Simulink.
