Abstract

Wide attention from academia and industry has been received for Multilevel Inverters (MLIs) as they offer high power capacity, lower harmonics, and lower switching losses. The usage of many switches in the conventional configuration causes a limitation, which leads to the development of a new topology with a switch count. This paper presents the development of Reduced Switch Single Source (RSSS) MLI, which can produce all voltage levels. The analysis of RSSS MLI is done using nine-level MLI, which consists of a few components compared to conventional topologies, thereby ensuring reduced size, minimum switching loss, and installation cost. The harmonic contents of the output voltage are obtained and compared using the carrier-based PWM technique. MATLAB/Simulink environment and experimental tests in the laboratory are used to validate the results.

利用基于多载波的 PWM 技术抑制新型多电平逆变器中的谐波
多电平逆变器(MLIs)具有功率容量大、谐波小、开关损耗低等优点,因此受到学术界和工业界的广泛关注。在传统配置中使用多个开关会造成限制,因此需要开发一种开关数量较少的新型拓扑结构。本文介绍了可产生所有电压水平的减少开关单源(RSSS)MLI 的开发情况。与传统拓扑结构相比,RSSS MLI 只由少数几个组件组成,因此可确保减小尺寸、降低开关损耗和安装成本。使用基于载波的 PWM 技术获得并比较了输出电压的谐波含量。MATLAB/Simulink 环境和实验室实验测试用于验证结果。
