Abstrakt: The main purpose of this article is to show the importance of a comparative analysis of a three-level neutral point clamped (3L-NPC) output voltage with selective harmonic elimination PWM (SHEPWM). As compared to other PWM technique, the SHEPWM method has a lower dynamic power loss and a better THD at the same switching frequency. The objective of this analysis is to provide a modelling results of THD and a voltage/current spectrum of the output voltage with a various SHEPWM implementation for the 3L-NPC converter. A mathematical model for this research was developed in Matlab/Simulink. A practical use of the comparative analysis results can be applied to power electronic systems of high power wind generators.
