摘要

由于可再生能源的影响，多电平逆变器的作用日益增强。但一般来说，所有的可再生资源都是直流形式，但利用是交流形式。本文旨在降低逆变器输出中的谐波含量。本文考虑的是H桥7级。采用多载波脉宽调制方法减小总谐波畸变。仿真结果表明，这些方法可以有效地降低THD水平。

Reduction of Odd Harmonics using Multilevel Inverter with Multi Carrier PWM Techniques

The role of multi level inverter's are increasing day by day due to the impact of renewable energy resources. But in general all the renewable resources are in form of DC, but the utilization is in AC form. This paper aims to reduce the harmonic content in the inverter output. The H Bridge seven level is considered in this paper. The multi carrier PWM routineare used to reduce the total harmonic distortions. The simulation result shows the THD level reduction by these methods.
