This paper proposes a novel online solution, i.e. Modified-Equilibrium Optimizer-Levenberg-Marquardt (M-EO-LM) algorithm, for the symmetric and asymmetric harmonic elimination pulse width modulation (HEPWM) methods of modular multilevel cascaded converters. A detailed comparison proposed M-EO-LM algorithm with nine state-of-the-art algorithms is also presented twenty-nine unimodal, multimodal c...

This paper describes ab initio electronic structure calculations on the planar transition states of 2-chloropropene leading to HCl elimination in the ground electronic state to form either propyne or allene as the cofragment. The calculations provide optimized geometries of the transition states for these two reaction channels, together with vibrational frequencies, barrier heights, and reactio...

An appropriate pulse-coding algorithm is the key to achieving an efficient switched-mode power amplification in all-digital transmitters. A five-level RF-PWM method with third and fifth harmonic elimination proposed relax requirements of filter reduce control complexity SMPA for By controlling pulse width center position three-level sub-pulses, achieved. Meanwhile, reduced by decrease output-si...

The multilevel inverters (MLIs) are capable of handling large quantities power and generating high-quality output voltages. Consequently, the size filters is reduced, circuitry simplified. As a result, they have diverse range uses in industrial sector, especially smart grids. input voltage boosting feature required to utilize MLI with renewable energy. In addition, number components attain high...

In this paper, a genetic algorithm (GA) optimization technique is applied to cascaded multilevel inverter to remove pre specified order of harmonics and to reduce THD. Genetic Algorithm is developed as the preferred solution algorithm of specific harmonic elimination (PWM-SHE) switching pattern.
