Abstract

Finding the optimal firing angles that minimize the amount of harmonics in a multilevel inverter is an optimization problem. However, since these values are available, testing them in an inverter is not something that can always be done since there is not always a physical inverter to carry out the tests. This paper proposes the development of a Simulink script that allows, from the input angles, to determine the typical ladder output waveform, as well as the harmonic content of an 11-level triphasic multilevel inverter. This will be done by designing the inverter by implementing Simulink IGBTS modules in a configuration of 5 H-bridges in series per phase. Furthermore, Fourier analysis of these waves is carried out in order to characterize the harmonic content of the generated signals.
