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.
Electromagnetic transformers have become obstacles to progress power supply miniaturization. Thus, piezoelectric transformers, which are more compact, immune to magnetic field and that present a high galvanic insulation, become more and more an alternative ...
In the frame of this thesis, we have developed a novel batch-type technology for the realization of three-dimensional millimeter-size transformers for ultra-small low-power (0.1-1 Watt) applications. The technology is based on the three-dimensional micropa ...
This paper deals with the determination of large synchronous machine characteristic quantities using an extended 2D-finite element method and based on the knowledge of the geometry and of the physical properties of the electrical and magnetic circuits of t ...
Excitation circuit is formed by a single planar coil of an essentially square shape (9) with the magnetic core (10) in the f of a diagonal cross with the legs (101, 102) extending towards the corners of the square defined by the outer circumference (90) th ...
It is possible to determine the types and values of stator and rotor errors in magnetic circuits in a synchronous machine by measuring the induced voltage (ui) for the terminals of measurement loops (2) which can capture an image of the induction in the me ...
The present paper deals with a new approach for the study of the steady-state and transient behaviour of phase transformers. This approach based on magnetic equivalent circuit diagrams, takes into account the nonlinear B-H curves as well as zero-sequence f ...
The manufacturing method for components of the inductive type, in particular inductance coils, transformers or antennae, consists in making by micro-machining simultaneously on a first substrate made of magnetic material a plurality of first parts (1) conn ...
The present paper deals with a new approach for the study of the steady - state and transient behaviour of three- phase transformers. This approach based on magnetic equivalent circuit diagrams, takes into account the nonlinear B-H curve as well as zero-se ...
