Comprehensive study of various configurations of three-phase Multilevel inverter for different levels

In the arena of power conversion technology, Multilevel inverter topology has emerged as a significant substitute. With increase in voltage levels at the output, total harmonics distortion reduces resulting good power quality and reduced switching losses. In this paper, a broad study of multilevel inverters (three phase) i.e. cascaded H-bridge multilevel inverter, Neural point clamped multilevel inverter, Flying capacitor multilevel inverter. It mainly focused on THD spectrum of each mentioned configuration with increase in number of voltage levels at the output, being simulated in MATLAB/SIMULINK environment.
