Abstract

In this article, a new 7-level boost Multilevel Inverter (MLI) is explained. It involves the use of self-balanced switched capacitors. Compared to other inverter topologies, it has less number of switching components. Moreover, the power switches have low stress which adds to the distinct features of the proposed MLI. The simulation analysis along with the experimental verification has been done in order to test the proposed circuit in different conditions. MATLAB software is used for doing simulation whereas the experimental results have been taken by using a laboratory prototype. Along with this, the loss analysis of the proposed MLI has been done, which comprises of the details of the losses occurring in the power electronic switches. The results of the loss analysis has been presented and explained in the paper. PLECS software is used for carrying out the power loss analysis. The high frequency level-shifted pulse width modulation (PWM) technique has been used for generating switching signals. A comparative study has been provided to understand the superiority of the MLI discussed in this paper.

基于自平衡开关电容的三倍电压增益和减少开关元件的7电平多电平逆变器

本文介绍了一种新型的7电平升压多电平逆变器(MLI)。它涉及到使用自平衡开关电容器。与其他逆变器拓扑结构相比，它具有较少的开关元件数量。此外，功率开关具有低应力，这增加了所提出的MLI的独特特征。为了测试所提出的电路在不同条件下的性能，进行了仿真分析和实验验证。采用MATLAB软件进行了仿真，并利用实验室样机取得了实验结果。与此同时，本文还对所提出的MLI进行了损耗分析，其中包括电力电子开关中损耗的细节。本文给出了损耗分析的结果并进行了说明。采用PLECS软件进行功率损耗分析。高频电平移脉宽调制(PWM)技术被用于产生开关信号。通过对比研究，了解了本文所讨论的多语交互的优越性。
