APPLICATION OF GENETIC ALGORITHM TO MINIMIZE HARMONIC IN MULTILEVEL INVERTER
Abstract: In inverter design,
harmonic voltage is the main issue which affects the performance of the inverter.
Generally, the harmonic minimization problem complexity is influenced by the
number of harmonic orders to be minimized. This paper presents the utilization
of genetic algorithm (GA) to solve harmonic minimization problem in multilevel
inverter. The objective is to find relationship between the number of minimized
harmonic orders and the results of total harmonic distortion (THD). The
inverter to investigate is 11-level, but it is also applicable to multilevel
inverters with any number of levels. The results show that harmonic contained
in the output voltage has a small dependence on the number of harmonic orders
that are minimized. However, the best results are still satisfied even though
involving higher number of harmonics. The best-obtained THD, evaluated until
19th harmonic, is 2.76%, which is fairly low and thus acceptable.
