This paper deals with the modeling of multi-windings transformers. Based on a real example, a modeling methodology is presented. This methodology is the original part of the paper. Application examples of multi-windings phase shifting transformers (18 and ...
The paper deals with the main problems to solve in order to simulate precisely the behavior of complex power systems with mixed elements (power components and digital regulation devices). The main features of an efficient simulation tool are described. The ...
The present paper presents an automatic approach for the determination of the parameters of laminated salient-pole synchronous machines, based on 2D finite element method (FEM). Calculations using FEM are performed in rotation (sudden three-phase short-cir ...
A new converter topology for drives is presented in this paper: a three-phase multilevel converter with separately regulated dc power supplies. The dc voltages are provided by medium-frequency dc–dc converters. The applications for the converter are especi ...
The use of a static frequency converter which is inserted between the grid and the stator is a well known solution to achieve an adjustable speed machine. Adjustable speed drive systems have already been applied in the past to hydro power plants. Up to now ...
Three-phase multilevel converters were proposed to feed high-power induction drives or highspeed drives for flywheels. This paper describes a new vector modulation method together with the vector control for a three-phase multilevel converter. The proposed ...
NOVELTY - For control mono-phase or multiphase machines in motor or generating mode with or without pulse width modulation. USE - Control of electrical rotating machines. ADVANTAGE - Can be used for control of single phase and three phase machines. DETAILE ...
The use of a static frequency converter which is inserted between the grid and the stator is a well known solution to achieve an adjustable speed machine. Adjustable speed drive systems have already been applied in the past to hydro power plants. Up to now ...
In this paper, a high quality single-phase rectifier with reduced ripple of the input current is proposed. the chosen solution has the main advantage of reducing cither the current ripple or the operating switching frequency, by a compensation effect of tw ...
The paper describes the control technique for a matrix converter and it's microcomputer based hardware implementation for a four-quadrant induction motor drive system. Special emphasis is given to the sinusoidal output voltage and input current modulation. ...
