Optimal Control Development System for Electrical Drives
("Dunarea de Jos" University of Galati, 2008)
In this paper the optimal electrical drive development system is presented. It
consists of both electrical drive types: DC and AC. In order to implement the optimal
control for AC drive system an Altivar 71 inverter, a ...
Power Conditioning System Topology For Grid Integration of Wind and Fuel Cell Energy
("Dunarea de Jos" University of Galati, 2006)
This paper shows the topology of the hybrid grid-connected power system and the performances of the front-end three-phase power inverter. The renewable sources of the hybrid power system consist of a solid oxide fuel cell ...
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 ...
Energetic Optimal Control of Adjustable Drive Systems
("Dunareade Jos" University of Galati, 2002)
In the paper is developed a new control strategy for the adjustable speed
drives. The strategy consists in the energetic optimal control of the dynamic regimes as
starting, stopping and reversing. The main developed ...
On the harmonics reduction using wavelet based signal processing
("Dunarea de Jos" University of Galati, 2000)
This paper presents a method for calculating the reference currents needed for
the command of an active filter. By using the Discrete Wavelet Transform (DWT) the
high-frequency components of the currents are eliminated. ...
A Simple Load Power Estimator for Quasi-Direct AC-AC Converter System
("Dunarea de Jos" University of Galati, 2003)
In this paper a simple load power estimator for the three-phase quasi-direct acac
converter system is reported. Since the ac-ac converter control by means of pulsewidth
modulation (PWM) is based on the power balance ...
