A New Cabled Stabilizer for the Nb3Sn React&Wind DEMO Conductor Prototype

Pierluigi Bruzzone, Kamil Sedlák, Boris Stepanov, Mithlesh Kumar, Vincenzo D'Auria

A Nb3Sn based, React&Wind flat cable, named RW2, was developed in the past three years at the Swiss Plasma Center in the scope of the EUROfusion conceptual studies for DEMO. The test results presented earlier proved an excellent DC performance, but large e ...

Preliminary Design of DEMO PF Coils Based on EU DEMO 2018 Baseline

Pierluigi Bruzzone, Kamil Sedlák, Mithlesh Kumar

The dimensioning of Winding Packs and allocation of materials in DEMO PF coils is proposed based on the requirements defined by the EUROfusion 2018 DEMO baseline. The coils are pancake-wound and use two types of forced flow cable-in-conduit conductors. The ...

97.4%-Efficient All-GaN Dual-Active-Bridge Converter with High Step-up High-Frequency Matrix Transformer

Elison de Nazareth Matioli, Armin Jafari, Palliyage Srilak Nirmana Perera

In this work, we demonstrate a state-of-the-art high step-up/down dual-active-bridge (DAB) converter designed with GaN transistors, to achieve a high efficiency and large power-density. A quasi-planar matrix transformer with high step-up/down ratio is demo ...

Regulating the anomalous Hall and Nernst effects in Heusler-based trilayers

Jean-Philippe Ansermet, Haiming Yu, Simon Granville, Sa Tu, Junfeng Hu, Song Liu

Anomalous Hall and anomalous Nernst properties of thin MgO/Co-2Fe0.4Mn0.6Si/Pd stacks with perpendicular magnetic anisotropy (PMA) revealed the presence of the magnetic proximity effect (MPE) in the Pd layer. The MPE is evidenced by nanometer range thickne ...

Very-High-Speed Miniaturized Permanent Magnet Motors: Modeling and Experimental Validation

Yves Perriard, Guillaume Paul-André Burnand

The purpose of this paper is to present an experimental method to separate losses components due to the rotation of the rotor in very-high-speed permanent magnet machines with ball bearings. In addition, it presents and validates an analytical model for th ...

Laboratory electromagnets: from the beginnings to Electromagnet Laboratories

Jean-François Loude

The mechanical action on iron of the first horseshoe electro-magnets (1824) was obvious. Their use to investigate more subtle magnetic, magneto-optical, atomic or nuclear properties of matter began in 1845 with Faraday. Until the first iron-less Bitter mag ...

Permeance Based Modeling of Magnetic Hysteresis with Inclusion of Eddy Current Effect

Drazen Dujic, Min Luo, Jost Allmeling

Magnetic hysteresis together with eddy current effects are typically present in metal based core materials and contribute significantly to the nonlinearity and power loss of the magnetic components operating in power electronic converters. In order to inve ...
