Critical Analysis on Multilevel Inverter Designs For Renewable Energy Grid

Abstract

Multilayer Inverter technologies have recently gained popularity as a cost-effective option for a number of engineering uses utilizing renewable sources of energy. This arrangement has a few noteworthy properties, including a lower hardware complexity, reduced switching losses, a smaller number of switches, and a better output voltage/current waveform. The reduction of total harmonic distortion is the most important requirement in multilayer inverters. Focus on the benefits; MLI technologies, including industrial equipment depending on a multilayer inverter architecture, have seen great growth. A review of traditional MLI and newly developed MLI is covered in this work. These seem to be the most extensively used power electronic devices in purposes such as motor-drive applications, solar as well as wind power MLIs, and in distribution Grids. With valuable references, this study broadly compares several types of MLIs and their appropriate uses in terms of the number of layers used,the number of switches, and Total Harmonic Distortion.
