Electromagnetic Model of an Ironless Inductive Position Sensor

Yves Perriard, Alessandro Danisi

An ironless position sensor is a novel sensing structure which exhibits intrinsic immunity to external magnetic fields, since it is characterized by air-cored supply and sensing windings. This new solution may be of significant interest for applications wh ...

Status Report of the EDIPO Project

Pierluigi Bruzzone, Rainer Wesche

The aim of this paper is to present an up to date review of the status of the European DIPOle (EDIPO) project whose objective is to build a new facility to perform both DC and AC tests of large superconductor samples in high magnetic background field (up t ...

Tunable thin film bulk acoustic wave resonator based on BaxSr1-xTiO3 thin film

Alexander Tagantsev, Nava Setter, Paul Muralt, Andreas Nöth

A tunable membrane-type thin film bulk acoustic wave resonator (TFBAR) based on a Ba0.3Sr0.7TiO3(BST) thin film has been fabricated. The resonance and antiresonance frequencies of the device can be altered by applying a dc bias: both shift down with increa ...

Turbulence Phase Space in Simple Magnetized Toroidal Plasmas

Paolo Ricci

Plasma turbulence in a simple magnetized torus (SMT) is explored for the first time with three-dimensional global fluid simulations. Three turbulence regimes are described: an ideal interchange mode regime, a previously undiscovered resistive interchange m ...

Modeling and Control of a Magnetically Levitated Planar Motor

Alireza Karimi, Roland Longchamp, Marc Kunze

This paper deals with the modeling and control of a magnetically levitated planar motor. The actuator considered has moving coils and stationary magnets. The principal objective is to develop a model which can be implemented in simulation. Therefore, the d ...

Optimization of shielded PCB air-core toroids for high efficiency dc-dc converters

Maher Kayal

The paper describes the design of optimized PCB air-core toroids for high frequency DC-DC converters with strict requirements in terms of volume and noise. The effect of several design parameters on the overall inductor volume, on DC and AC winding resista ...

Test results of a large size, forced flow Nb3Sn conductor, based on a design alternative to the cable-in-conduit

Pierluigi Bruzzone, Rainer Wesche, Boris Stepanov

An R&D program at CRPP investigates the design of large size Nb3Sn conductors, with the aim to improve the effectiveness and hence the cost of large size, force flow conductors. A design based on a solder filled flat cable, by react wind method, is selecte ...

Large low speed hydrogenerators - UMP and additional damper losses in eccentricity conditions

Stefan Keller

The present thesis is an advanced contribution to the design process of large synchronous generators with high number of poles. It proposes two original contributions, the first one allowing a very precise prediction of the no-load voltage and of the no-lo ...
