In multilevel inverters (MLI), output voltage waveform consists of dominant low order harmonics, which needs to be minimized. Simultaneously, good control over the fundamental for desirable operation is needed. this paper, an atom search optimization (ASO) based selective harmonic elimination (SHE) method proposed a variable dc bus reduced component count (RCC) MLI. ASO population-based metaheu...

This paper proposes a harmonic reduction approach and output voltage regulation in pulse width modulation (PWM) based AC Chopper using artificial intelligent technique. The optimal switching angles are provided by artificial intelligent technique to minimize harmonic distortions. In addition, the simulation results are correlated to confirm the performance in terms of power factor by improving ...

In this paper, a fully-digital-controlled hybrid series active filter (HSAF) for harmonic elimination and reactive power compensation in single phase systems is presented. The HSAF is composed of two single tuned LC filters and a small-rated active filter. Discrete Fourier transformation is used as the control method. Simulation results using MATLAB program shows the effectiveness of the contro...

This paper describes the current-detection algorithm based on the time-domain approach for three-phase shunt active power filters (APFs). It aims at eliminating harmonics and/or correct power factor and/or balance asymmetrical loads are analyzed. An overview and assessment of the performance of existing current-detection algorithms for active power filters are presented. According to different ...

Many inverters play an important role in transmitting and processing energy to power system networks. To reduce the cost size of multilevel inverters, various topologies have been included literature. But these do not look at complete harmonic distortion output waveform. In this study, a modern inverter structure, mutated H-bridge is adopted that demands small amount switches, driver circuits, ...

Most of the pollution issues created in power systems are due to the non-linear characteristics and fast switching of power electronic equipment. Power quality issues are becoming stronger because sensitive equipment has been more sensitive for market competition reasons, equipment will continue polluting the system more and more due to cost increase caused by the built-in compensation and some...

In this paper, a hysteresis current control technique for a single-phase five-level inverter with cascaded H-bridge topology is proposed. The basic study to implement the logic for correct voltage-level selection, various schemes available in the literature have been described and will provide a useful framework and point of reference for the future development of hysteresis modulation for mult...

The growing use of nonlinear devices is introducing harmonics in power system networks that result distortion current and voltage signals causing damage to distribution systems. Therefore, systems, the elimination great significance.
