Graph Chatbot
Chattez avec Graph Search
Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
In this article the development and realization of a 8 kW battery charger with Power Factor Correction (PFC) is described. The converter consists of two parts: The first part is an AC/DC converter based on a “VIENNA” topology with a controlled output volta ...
Besides the option of HTS cables as retrofit elements in densely populated areas, the technically most attractive aspect of HTS is the possibility of high power transmission at reduced voltage. In this paper we concentrate on this second aspect. High power ...
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 ...
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 ...
This paper examines the use of thyristor controlled series capacitors (TCSCs) for the redistribution of active power flows (PFs) in a transmission network and presents a simple model of a hierarchical coordinated control system for multiple devices. The TC ...
An analytical approach allowing modelling transient phenomena in pipes, valves, surge tanks and Francis turbines based on impedance method is developed. These models are implemented in a software called “SIMSEN”, which simulates the behaviour of complex ap ...

This paper studies the problem of state regulation for uncertain state-space models. It formulates a new weighted game-type cost function with bounds on the sizes of the uncertainties in the data. The cost function is of independent interest in its own rig ...
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 ...
Fuel Cells are destined to supply electric energy beginning from primary resources. A static DC-AC converter is necessarily inserted between the fuel cells and the distribution network. This paper describes a new P.W.M. strategy for a current source invert ...
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 ...
