Magnetic Loss Versus Frequency in Non-Oriented Steel Sheets and Its Prediction: Minor Loops, PWM, and the Limits of the Analytical Approach

The Pulse Width Modulation (PWM) technique is commonly used to supply modern high-speed electrical machines. The fundamental frequency is typically in the kilohertz range, with switching frequencies of several tens of kilohertz, as determined by the…

The dynamic multifractality in PEMFC stack voltage signal as a tool for the aging monitoring

Fuel Cell aging monitoring and diagnosis are key-issues for scientists and industrials who intend to spread this technology. In the present work, we propose an efficient method that enables the extraction of valuable information which contains…

Robust-COMET for Covariance Estimation in Convex Structures: Algorithm and Statistical Properties

This paper deals with structured covariance matrix estimation in a robust statistical framework. Covariance matrices often exhibit a particular structure related to the application of interest and taking this structure into account increases…

Supporting the laminated ferromagnetic pole pieces in a magnetic gear: a structure behaviour analysis from a multibody model

This paper deals with the structure behaviour of a multi-bar system which maintains pole pieces in a magnetic gear. A simplified model of the system is proposed in order to be integrated in a multi-criteria global optimization for the sizing of a…

Borne Bayésienne pour les systèmes large-échelle : cas d'un bruit à queue lourde

Nous nous intéressons dans ce travail à l'étude de bornes de Cramér-Rao Bayésiennes dans le cadre de l'estimation robuste de paramètres pour un bruit non-Gaussien. En effet, les mesures observées peuvent être perturbées par des réalisations de bruit…

Unshielded Cable modeling for Conducted Emissions Issues in Electrical Power Drive Systems

In power electronics applications, high frequency models for cables are necessary to understand EMI issues in pulsewidth modulation drives. This paper shows the approach developed at the French Institute of Technology (IRT) Saint-Exupery, in order…
