Harmonics can be characterized as components with periodic waveforms having multiples of a fundamental frequency. Harmonics, one of the most critical issues of power quality, have recently come into prominence despite being known in advance. Many scientists and researchers have suggested various methods for decreasing or eliminating these low-order and high-order harmonics since the early time of the ac power systems. Selective Harmonic Elimination Method (SHEM) in the proposed methods is shown superior performance on low-order harmonics in low switching frequencies. Various Meta-Heuristic Algorithms (MHA) are used to solve the equations included in this method and to reduce the computational burden. In this study, Grey Wolf Optimizer (GWO) which is a metaheuristic method added to literature in recent history, is applied to 3-phase Voltage Source Inverter (VSI) system using SHEM for harmonic elimination. GWO technique is analyzed and implemented for calculating the switching angles for Voltage Source Inverter (VSI). Total harmonic distortion (THD) values of GWO and without GWO methods of the inverter system are also compared with Cuckoo Search (CS) and Genetic Algorithm (GA). Our results show that using GWO method eliminates low-order harmonics and reduces THD value of the system according to power quality standards.

Selective Harmonic Elimination for Three-Phase Voltage Source Inverters Using Whale Optimizer Algorithm Nalcaci, Gamze; Ermiş, Muammer (2018-05-05) Selective Harmonic Elimination (SHE) shows superior harmonic performance at low switching frequencies to eliminate low-order harmonics and this property decreasing losses is a very effective way to reach higher efficiencies in power electronics applications. In this paper, Whale Optimizer Algorithm (WOA) is implemented to decide optimum switching angles for three-phase Voltage Source Inverter (VSI) of eliminating some high order harmonics while providing the required voltage. Besides, Particle Swarm Optimiz...
Effect of parallel and antiparallel configuration on magnetic damping in Co/Ag/Co/Gd Demirtas, S.; Salamon, M. B.; Koymen, A. R. (AIP Publishing, 2011-06-01) When two ferromagnetic layers have a common resonance frequency, the usual spin-pumping broadening may be reduced by dynamic exchange coupling. Utilizing the antiferromagnetic coupling between Co and Gd, we explore the change in ferromagnetic resonance accompanying a spontaneous transition from parallel to antiparallel magnetic alignment of two Co films below the compensation temperature T-comp. Above T-comp, the data are consistent with conventional models. However, a rapid doubling of magnetic damping acc...
Effects of array guided surface waves on radiation characteristics of a finite planar printed dipole array Aydın Çivi, Hatice Özlem; Pathak, PH (2004-06-26) The presence of surface waves different from the conventional grounded dielectric substrate surface wave modes, which can be excited on a finite periodic radiating array of printed dipoles, at frequencies for which the spacing between dipoles is typically less than half a wavelength is studied. The effects of such array guided surface waves on the array radiation characteristics are investigated. Techniques to suppress these surface waves are also discussed.
Output Ripple Performance Evaluation and Comparison of 2L-VSI and 3L-VSI Considering the Spectral Characteristics Özkan, Ziya; Hava, Ahmet Masum (2015-06-05) In this paper, two-level and three-level voltage source inverters (2/3L-VSIs) with popular pulse width modulation (PWM) methods are investigated in terms of their output (ac-side) voltage and current ripple spectral characteristics and waveform quality properties such as peak-to-peak ripple, rms ripple, and weighted total harmonic distortion. As the switching frequency and the filter size influence the output waveform quality, the inverter efficiency (loss) constraint on the switching frequency, and the siz...
