Investigations on Different Multilevel Inverter Control Techniques by Simulation

Abstract

This paper presents simulation studies on different control techniques of 3- and 5- level diode clamped multilevel inverters i.e. sinusoidal PWM, selective harmonic elimination, and optimized harmonic PWM techniques. Paper contributes towards the detailed simulation and analysis of these techniques which has not been given in previous work. The performance of each technique has been investigated based upon reduction in total harmonic distortion. For simulation, Matlab/Power System Blockset/PowerGUI has been used.
