Design of LCL Resonant Converter for Electrolyser
("Dunarea de Jos" University of Galati, 2010)
An Electrolyser linked with a DC bus are analyzed and discussed in this paper.
An electrolyser is a part of renewable energy system which generates hydrogen from
water electrolysis. An LCL series parallel resonant converter ...
Integrated Solid Oxide Fuel Cell Power System Characteristics Prediction
("Dunarea de Jos" University of Galati, 2009)
The main objective of this paper is to deduce the specific characteristics of the
CHP 100kWe Solid Oxide Fuel Cell (SOFC) Power System from the steady state
experimental data. From the experimental data, the authors have ...
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 ...
A Distortion Input Parameter in Image Denoising Algorithms with Wavelets
("Dunarea de Jos" University of Galati, 2009)
The problem of image denoising based on wavelets is considered. The paper
proposes an image denoising method by imposing a distortion input parameter instead
of threshold. The method has two algorithms. The first one is ...
Analysis and Design of Embedded Controlled Parallel Resonant Converter
("Dunarea de Jos" University of Galati, 2009)
Microcontroller based constant frequency controlled full bridge LC
parallel resonant converter is presented in this paper for electrolyser application.
An electrolyser is a part of renewable energy system which generates ...
Power Estimation of Pipeline FFT Processors
("Dunarea de Jos" University of Galati, 2009)
Pipeline FFT processors are used in mobile communication systems and in
particular in OFDM-based systems. This paper presents a method for power analysis of
pipeline FFT processors. This method applies to various ...
Channel Allocation Management Using Agents Technology
("Dunarea de Jos" University of Galati, 2009)
Channel allocation schemes are management techniques meant to solve the
radio access problem in the telecommunications area. There are several known schemes
namely: static, dynamic, hybrid and flexible channel allocation ...
Omline industrial Proces Broacast and Control Based on IP and Serial Networks
("Dunarea de Jos" University of Galati, 2007)
The Internet network in conjunction with a strong security policy can be an
ideal online broadcast system for the industrial processes monitoring and control. Because
the distributed controllers are connected through ...
Control of a Multivariable Web Winding System
("Dunarea de Jos" University of Galati, 2007)
To guarantee a good productivity and a better quality of the industrial systems, it is necessary to know the evolution of its various parameters but also its operation mode. The main goal of this work is to carry out a ...
Thermal Processes Identification Using Virtual Instrumentation
("Dunarea de Jos" University of Galati, 2007)
In this paper the experimental identification problem of thermal processes is presented, in order to establish their mathematical models which permit the adoption of the automation solutions, respectively the specification ...
