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 ...
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 ...
In this work, a model of a multi-layer high-Tc superconducting (HTS) cable that computes the current distribution across layers as well as the AC loss is presented. Analyzed is the case of a four-layer cable, but the developed method can be applied to a ca ...
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 ...
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 ...
This paper presents results from numerical modelling of non-twisted multifilamentary Bi-2223/Ag conductors with various geometry and filament arrangement. New anisotropic models of Jc(B) and n(B) have been employed in finite element method simulations unde ...
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 giant magnetoimpedance (GMI) and giant magnetoresistance (GMR) of amorphous ribbon/Cu/amorphous ribbon trilayer microstructures, based on Metglas(TM) 2714a ribbons and Cu foils, is measured and analyzed. We obtain GMI and GMR ratios of 830% and 2630%, ...
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 ...
