Optimization of SHEPWM cascaded multilevel inverter switching patterns
International Journal of Power Electronics and Drive Systems (IJPEDS), 2020 Selective harmonic elimination (SHE) is an efficient method to eliminate low-order selected harmonics. However, due to nonlinearity in the problems, many optimization techniques give unsatisfied performances in finding optimum switching angles for the SHE. This paper proposes a modified moth-flame optimization algorithm to eliminate selective harmonics
