Abstract

Nowadays, multilevel inverters (MLIs) are receiving profound attention to cater the power requirements of industry 4.0. In this context, newer MLI topologies are being explored as well as proposed with reduced component counts to attain higher levels of output voltage. In this context, this article illustrates the comparative analysis of sinusoidal pulse width modulation (SPWM) with two different carrier wave and low frequency modulation (LFM) for a 3-phase symmetrical modular multilevel inverter (M-MLI) with reduced component counts. Since, this topography is uncomplicated and modular, it could be extended to several levels by rising the number of cells. The M-MLI topology having 3-levels in each pole with a single fundamental cell in each phase is simulated in MATLAB/Simulink. The %THD of M-MLI using LFM scheme is found less compared to other two techniques which are demonstrated through FFT analysis.

减少开关数的三相对称多电平逆变器不同开关方案的比较评价与分析

如今，多电平逆变器(mli)正在受到广泛关注，以满足工业4.0的功率要求。在这种情况下，新的MLI拓扑结构正在被探索，并提出了减少元件数量以获得更高水平输出电压的方案。在这种情况下，本文说明了具有两种不同载波的正弦脉宽调制(SPWM)和具有减少分量计数的3相对称模块化多电平逆变器(M-MLI)的低频调制(LFM)的比较分析。由于这种地形不复杂且模块化，因此可以通过增加细胞数量来扩展到几个层次。在MATLAB/Simulink中模拟了每极具有3电平、每相具有单个基元的M-MLI拓扑结构。通过FFT分析发现，与其他两种技术相比，使用LFM方案的M-MLI的%THD较小。
