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 the available literature, including reference books on the topic, the spectral analysis of voltage waveforms obtained through the use of pulse-width modulation relies on the assumption of an ideally flat voltage across the DC link of a considered switch ...
Early diagnosis of Alzheimer's and epilepsy requires monitoring a subject's development of symptoms through electroencephalography (EEG) signals over long periods. Wearable devices enable convenient monitoring of biosignals, unlike complex and costly hospi ...
A telemetric device with electronics comprises at least one of a sensor, an actuator or a data transmission device; at least one super-capacitor arranged as a power storage and a supply voltage for the at least one of a sensor, an actuator or a data transm ...
The global problem of energy supply and the reduction of the carbon footprint can only be solved by a massive replacement of fossil fuels or atomic energy by renewable resources.
As the latter are mostly weather-dependent, they are uncontrollable and unpre ...
A new feed-forward control technique for a DC-DC step-up converter based on the asymmet-ric Multistage Stacked Boost Architecture (MSBA) is presented in this paper. The proposed closed loop control scheme can provide improved accuracy in the steady-state o ...
A non-isolated DC-DC converter is presented, based on the current diverter principle. The converter is foreseen for large power electronic applications where normally the converters are fed from DC supplies at a typical voltage level of around one or two k ...
With the evolution of power electronics technologies, DC networks have been considered as promising distribution systems for future grids. This new concept of power systems comes with technical challenges in protection coordination, a result of the no natu ...
DC shipboard power systems have been connsidered as a promising solution for stricter environmental regulations on ships due to their main benefits in fuel savings with variable speed engines and easy integration of energy storage systems. In order to empl ...
With the implementation of energy efficiency regulations for all ships, DC shipboard power systems (SPS) have attracted much attention from the shipbuilding industry due to their advantages in fuel savings with variable speed engines and the closed bus-tie ...
High power variable speed drives play a major role in many industrial applications. At the moment, these high power loads are supplied by the source (grid/generator) through the state-of-the-art MVAC power distribution network. The voltage levels, in these ...
