Selective Harmonic Elimination Pulse Width Modulation (SHEPWM) is a well-known Switching Strategy which is applied in multilevel Inverters. The aim of this strategy is eliminating low order harmonics. Basically, harmonic equations are nonlinear and solving them is a major problem for researchers. Evolutionary Algorithms have shown an effective ability for this aim, because they find solution for all...
In the present work, the Selective Harmonic Elimination Pulse width Modulation SHE-PWM is used to improve the output voltage quality of the AC/AC choppers. To achieve the requirement of the SHE-PWM such as a desired fundamental magnitude and the elimination of the low order harmonics contained in the output voltage, two heuristic and evolutionary algorithms were used. The problem of the SHEPWM is...
