Convertisseur de fréquence indirect à rapport de tension fixe

Aziza Benaboud

Many electric power generators use gas turbines as power sources. Typically they are connected to the turbines through a mechanical gearbox in order to adapt their synchronous speed to the optimal rotation speed of the turbine, which is very often much hig ...

Multilevel Inverter for Power System Applications : Highlighting Asymmetric Design Effects form a Supply Network Point of View

Alfred Rufer

This paper highlights some effects of an asymmetrical design on three phase multilevel inverters from a supply network point of view. The investigated topology is based on a series connection of single phase inverters (partial cell) in each phase. Each par ...

A modular software package for the analysis of power networks and electrical drives

Jean-Jacques Simond, Alain Sapin

This paper deals with a software package for the numerical analysis in transient and steady-state modes of power electrical networks or variable speed drives with arbitrary topologies. The package is composed of a series of units, each representing a speci ...
