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 ...
Flexible AC Transmission Systems (FACTS) are systems based on power electronics using GTO or IGCT semiconductors [1] that allow a better use of the transfer capacities of the transmission lines and permit to satisfy the requirements due to the liberalizati ...
Nowadays, multilevel VSIs (Voltage Source Inverter) begin to be widely used in middle and high power installations such as variable speed drives, FACTS (Flexible AC Transmission System) and windformers for example. In these systems, 2 VSIs are put back to ...
An ac loss experiment on two Nb3Sn cable-in-conduit conductors (CICCs) is carried out in the SULTAN test facility using both magnetization and calorimetric methods to cover a broad range of frequency, from 0.03 Hz to 6 Hz. Loss curves are measured before a ...
The Laboratory of Electrical Machines of the Swiss Federal Institute of Technology (Lausanne) has developed a software (TLSim) for the simulation of electrical urban transportation systems. This program can simulate the behaviour of the power supply networ ...
The use of electrical equipment in rail and ship transportation is bound to consideration on mass and size, particularly because of conventional low frequency transformers. On this paper, an optimized multilevel converter with medium frequency transformer ...
Hybrid asymmetric multi-level inverters promise significant improvements for medium-voltage industrial drives. Floating sub inverters without feeding can only supply reactive power. An on-line non-linear model-predictive controller stabilizes their interme ...
The Commission E Open Meetings papers are a choice between a status report for the Working Group activity or a short presentation of a subject in the area of the respective WG, which seems more relevant for the period between two such Open Meetings. The di ...
The transmission of energy or signals to a rotating device is generally carried out by systems with sliding contacts. This technology, apparently simple, generates serious nuisance such as abrasion of the elements in contact, electric noises and requires a ...
In the technology sector of power electronics and control, the multilevel converter technology is still a rather new research area, but the application possibilities in the field of power drives and energy will demand more solutions with this promising tec ...
