    This article presents a three-phase modified nine-level multilevel inverter using Artificial Bee Colony Algorithm (ABC) to remove the low order harmonics. Low order harmonics can be fully removed from the output voltage and current waveform by using the proper switching angles. The non-linear equations derived from the Fourier series of the output voltage and current waveform were used to compute the switching angles. The ABC was created specifically for the suggested reduced switch approach topology to solve the nonlinear equation and generate the required switching angles. Simulator tools such PSIM was used to model the circuit, and experimental results were used to evaluate it. The 5th, 7th, and 11th order harmonics will be eliminated, and two modulation indices will be compared, and their performance measured in terms of overall harmonic distortion. THD results will be shown for modulation indexes of 0.58 and 0.83.

    This paper presents the nine-level multilevel inverter with reduces switch technique using Grey Wolf Optimization (GWO) methods on eliminating the low order harmonics. Using the appropriate switching angles, the low order harmonics can be eliminated completely from the output voltage and current waveform. The switching angles were calculated using the non-linear equations derived from the Fourier series of the output voltage and current waveform. In this paper, GWO algorithm was developed to solve the nonlinear equation and generate the appropriate switching angles specifically for the proposed reduced switch technique topology. The circuit were simulated using PSIM and evaluate based on experimental assessments. The targeted low order harmonic to be eliminated are the 5th, 7th and 11th and two modulation indices will be compared and observed it performance in term of value of total harmonic distortion. The THD results for modulation indexes of 0.7 and 0.82 will be displayed. For modulation index 0.7, simulation yields 7.52% and experimental yields 6.23%. The simulation result for modulation index 0.82 is 5.82% and the experimental result is 4.69%.
