Multilevel inverters (MLI) are popular in high-power applications. MLIs are generally configured to have switches reduced by switching techniques that eliminate low-order harmonics. The selective harmonic elimination (SHE) method, which significantly reduces the number of switching, determines the optimal switching moments to obtain the desired output voltage and eliminates the desired harmonic components. To solve the SHE problem, classical methods are primarily employed. The disadvantages of such methods are the high probability of trapping in locally optimal solutions and their dependence on initial controlling parameters. One solution to overcome this problem is the use of metaheuristic algorithms. In this study, firstly, 22 metaheuristic algorithms with different sources of inspiration were used to solve the SHE problem at different levels of MLIs, and their performances were extensively analyzed. To reveal the method that offers the best solution, these algorithms were first applied to an 11-level MLI circuit, and six methods were determined as a result of the performance analysis. As a result of the evaluation, the outstanding methods were SPBO, BMO, GA, GWO, MFO, and SPSA. As a result of the application of superior methods to 7-, 11-, 15-, and 19-level MLIs according to the IEEE 519—2014 standard, it has been shown that BMO outperforms in 7-level MLI, GA in 11-level MLI, and SPBO in 15- and 19-level MLIs in terms of THD, while in terms of output voltage quality, GA in 7-level MLI, BMO in 11-level MLI, GA and SPSA in 15-level MLI, and SPSA in 19-level MLI come forward.

“…This research paper compares three, five and thirteen level MLIs using the Selective Harmonic Elimination Pulse Width Modulation (SHE-PWM) switching technique. SHE-PWM is a modulation technique that switches at low frequency and provides tailored control of low-order harmonics and reduces switching losses [24], [25], [26], [27], [28]. In each case, MLIs will use SHE-PWM control scheme and the output voltage waveform of each has six notch angles (using quarter waveform symmetry).…”

This paper presents a detailed comparison of eliminated and non-eliminated harmonics for 3-level, 5-level and 13-level cascaded multilevel inverter. For this research, three different types of cascaded H-Bridge multilevel inverters are considered where each cascaded multilevel inverter generates a different output voltage, but the number of notch angles in all the three cases are kept identical. A unified approach is adopted to derive the mathematical model of each multilevel inverter output voltage waveform, RMS of output voltage, RMS of fundamental component, selective harmonic elimination system of equations for the low order harmonics elimination and output voltage total harmonic distortion. It is shown that since selective harmonic elimination system of equations can be expressed as a function of the notch angles, hence notch angles are determined while taking in account only those harmonics to be eliminated. The Newton-Raphson method is proposed to resolve the nonlinear transcendental equations of selective harmonic elimination for the three multilevel inverter cases. Consequently, once the notch angles are determined, all three multilevel inverters are analyzed by comparing Total Harmonic Distortion and Zero-Sequence Harmonics Factor. The elimination of triplen-harmonics by evaluating them in the non-linear transcendental system of equations is a significant contribution. The theoretical and simulated results are presented to verify the validity of the proposed work.

“…More recently, a comparative study between different optimization techniques to find precise switching angles for SHE modulation was made by Kundu et al (2018). The GA was used by Iqbal et al (2019) to solve the SHE optimization problem for a seven-level packed U-cell inverter and Kumar et al (2020) applied a Gravitational Search Algorithm and a Learning PSO to obtain optimized switching angles for seven and eleven level inverters.…”

This paper presents the application of genetic algorithm to determine optimized pulse patterns in multilevel inverters aiming to mitigate harmonics generated at the inverter output voltage while maintaining a desired modulation index. A new real representation based on a relative position approach is applied to the chromosome encoding in order to avoid the existence of infeasible solutions and a systematic diversity control of initial population is proposed based on the euclidean distance between individuals. A local search mechanism combined with an elitist selection is also considered. Fitness value frequency distribution, waveform patterns and its corresponding harmonic components are presented to illustrate the effectiveness of the proposed algorithm.
