Active Power Compensator of the Current Harmonics Based on the Instantaneous Power Theory
("Dunarea de Jos" University of Galati, 2005)The quality of the electrical current becomes a major concern. The proliferation of the power electronic converters, which are used extensively to control electrical apparatus in industrial and commercial applications (dc ... -
Active Power Filter with Indirect Control for Line-Frequency Controlled Rectifiers
("Dunarea de Jos" University of Galati, 2009)Line-frequency controlled rectifiers have two major disadvantages: variable displacement power factor and high harmonic current fed to the power supply. If the power converter is large, e.g. for rolling mills drives, it ... -
Adaptive Filter Used as a Dinamic Compensator in Automatic Gauge Control of Strip of Rolling Proceses
("Dunarea de Jos" University of Galati, 2010)The paper deals with a control structure of the strip thickness in a rolling mill of quarto type (AGC – Automatic Gauge Control). It performs two functions: the compensation of errors induced by unideal dynamics of the ...
