Harmonic estimation is essential for mitigating or suppressing harmonic distortions in power systems. The most important idea that spectrum analysis, waveform estimation, source classification, location, the determination of contributions, data clustering, and filter-based elimination capacity are also considered. feature extraction method a fundamental component optimization improves effective...

Selective harmonic elimination–pulsewidth modulation (SHE–PWM) is a technique widely used to improve the efficiency and content in medium-voltage high-power converters. Among these converters, three-level neutral-point-clamped (3L-NPC) converter one of most utilized topologies. However, 3L-NPC requires proper balancing dc-link capacitor voltages. This article presents control technique, based o...

This research paper proposes the new multi-criteria search based enhanced firefly algorithm for solving selective harmonic elimination in a multilevel inverter. utilizes adaptive nature of social and cognitive components to find global optima. To see effectiveness proposed evaluation results, three phase nine level cascaded inverter is used. It compared with existing meta-heuristic algorithms n...
