Réfrigération magnétique : des principes fondamentaux aux applications

The paper introduces the working principle of magnetic cooling, it hinges from a paper oriented towards magnetocaloric materials [k733] and one oriented towards cooling system [BE 9 830]. Based on thermodynamic analysis, it makes a strong link…

Anthracene and β-cyclodextrin-based semi-conducting rotaxanes: Effect of the benzylation on the physico-chemical and electrical properties

In this work, we report the benzylation of an anthracene and β-Cyclodextrin-based rotaxane. Then, a comparative study between the physicochemical and electrical properties of the modified rotaxane (R-Bn) and those of the pristine supramolecule (R)…

Optimisation topologique d’un rotor de MRV pour maximiser le couple moyen : un problème mal posé

Ce travail présente un problème d’optimisation topologique visant à maximiser le couple moyen d’une machine à réluctance variable. Les équations de la formulation duale magnétostatique s’identifient à un problème de maximisation de différence de…

Economic performance of an overplanted offshore wind farm under several commitment strategies and dynamic thermal ratings of submarine export cable

The overplanting of an offshore wind farm (OWF) with dynamic thermal ratings (DTR) is a promising solution for enhancing OWF performance. As the overplanted OWF generates an additional energy and DTR ensures its better transfer, the research…

A comparative study of Energy Management Systems for non-cooperative and cooperative Multi-Microgrids

Nowadays, Multi-Microgrids (MMGs) systems are emerging as one of the alternatives to enhance resiliency and sustainability of electrical energy systems. In spite of the obvious advantages of MMGs, it is necessary to focus on Energy Management System…

Skin effect and losses in soft magnetic sheets: from low inductions to magnetic saturation

High frequencies are ubiquitous in present-day power applications: most electrical equipment, like rotating machines, are supplied by Pulse Width Modulation (PWM) switching inverters, often working at tens or hundreds of kilohertz. PWM is…
