This paper presents the modeling, detailed simulation, and test of an efficient medium-voltage adjustable-speed drive. The system consists of a three-level neutral-point-clamped inverter supplied by a 12-pulse rectifier. To achieve a motor-friendly supply, ...
In the frame of the European project UNIFLEX-PM, two AC/AC converter topologies hove been studied and implemented. Both converters, rated for 25 kVA, are isolated by a medium-frequency power transformer. The first topology is based on a dual active bridge ...
The aim of this paper is to present a universal power quality conditioning system (UPQS) named after unified power quality conditioner, which is extended by adding a shunt active filter at the load side. Its main purpose is to compensate for both supply vo ...
Nowadays medium voltage conversion systems, like traction and energy distribution systems, aim to increase power density. Volume, weight and material reduction are gaining the market today. Due to the development of new high power semiconductor devices a n ...
Recently, multilevel applications have know n many improvements. Initially introduced to answer the problem of the series-connection of components in medium voltage applications, multilevel topologies have now to serve new purposes. Recent multilevel techn ...
State-of-the-art low voltage (LV) medium and high power variable speed drives are voltage source converters. Frequently, frond-end stage is a diode rectifier. To reduce the amount of input current harmonic,, multi-pulse rectifiers are used. Due to the high ...
The paper introduces an advanced multilevel-based power converter structure for flexible power management of future electricity networks. The structure is then analysed so that appropriate control approaches are proposed in order to overcome technical chal ...
The paper presents a generalised approach towards the development of the space vector pulse width modulation (SVPWM) for sinusoidal output voltage generation with two-level multiphase voltage source inverters (VSIs), where the number of phases is an odd nu ...
The stability and the dimensioning of a step-down switching voltage regulator feedback loop remain a complex task. An analytical approach allows dimensioning of all the components, strongly facilitating this task. In this article, a mathematical analysis i ...
This article presents a new technique for improving the linearity performance in biquadratic transconductor-C filters. This improvement has been achieved by applying some modifications to the filter topology which considerably relaxes the linearity require ...
