Total Harmonic Distortion Minimization of Multilevel Converters Using Genetic Algorithms
2013
This paper presents a genetic algorithm (GA)
optimization technique to find the optimum switching angles of 11-level
inverter with minimum number of dc sources and switches in comparison with the
cascade multilevel inverter in order to minimize the total harmonic distortion
(THD) of their output voltage waveform. Theoretical and simulation results for
an 11-level converter show the efficiency of the proposed algorithm to
determine the optimum angles in order to decrease the undesired harmonics and
produce very high quality output voltage waveform.
