A Survey on Conventional Multilevel Inverter Topologies

Multilevel inverters have gained significant attention in recent years due to their ability to minimize switching losses, improve the quality of output voltage waveforms, and attenuate voltage harmonics. They have several advantages over the traditional two-level inverter. This research paper provides a thorough comparative analysis of various multilevel inverter topologies, highlighting their distinctive characteristics, advantages, and limitations. This study, uses simulations to systematically compare multilevel inverter topologies, including the Diode Clamped, Flying Capacitor, and Cascaded H-Bridge inverters based on various parameters. A quantitative comparison between these three standard topologies provides a basis for research being carried out in terms of modern topology propositions.
