A Multilevel PV Inverter Control With Minimal Total Harmonic Distortion (THD)
In this article, we have improved the control of the multilevel inverter for a photovoltaic system connected to the grid, in order to minimize the total harmonic distortion of current. This topology being considered as a new converter topology applied to photovoltaic systems and has the advantage of very high-energy efficiency, but has the disadvantageLamreoua Abdelhak +4 more

A nonlinear system determines the quality of power under closed and open control. An issue with power is overcome by a three-phase DC/AC embedded DC/DC ZETA converter with proposed Hysteresis Current Controller (HCC). In this proposed system, personal computers are operated in order to record harmonic generation.

Integrating renewable energy resources especially photovoltaic systems with microgrids has become an unavoidable choice for most countries and in Egypt the government has this ambition to reach a percentage of 20% of the total national electricity generation from solar energy. Which in turn bring some challenge to the electrical utility operator.

A simple and cost-effective solution to reduce the passive filter terminal voltage total harmonic distortion (THD) is outlined. A modified synchronous reference frame (SRF) based controller for the series active filter allows injection of a controlled percentage of the higher harmonic load currents into the supply, in compliance with the IEEE 519 ...

The electric motor has replaced motor fuel as the main mover of the equipment. One of them is the use of a three-phase induction motor in the industrial sector. Equipment in an industry requires many speed controllers in operation. The induction motor speed can be changed by changing the number of poles, changing the stator voltage, and changing the ...

With the standard IEEE 519-1992 Refers harmonics can be identified by comparing the measurement results with those standards so it can be known whether a certain point (point of common coupling) are harmonics. Where the percentage of allowable voltage below 69 kV attached to harmonic voltage is 5% while for Total Harmonic Distortion (THD%)current is 15%

In this paper, we present an approach for Polymer Electrolyte Membrane Fuel Cell (PEMFC), drying out and flooding diagnosis. The present approach is signal-processing-based pattern recognition. The voltage signal is processed by a Fast Fourier Transform, in order to carry out a frequency analysis and to calculate the Total Harmonic Distortion (THD ...
