Broadband excitation and indirect detection of nitrogen-14 in rotating solids using Delays Alternating with Nutation (DANTE)

Geoffrey Bodenhausen, Simone Ulzega, Marc Anthony Caporini

A train of short rotor-synchronized pulses in the manner of Delays Alternating with Nutations for Tailored Excitation (DANTE) applied to nitrogen-14 nuclei (I = 1) in samples spinning at the magic angle at high frequencies (typically nu(rot) = 62.5 kHz so ...

Electroacoustic absorbers I: bridging a gap between active acoustic feedback control and shunt loudspeakers

Romain Christophe Rémy Fleury, Hervé Lissek, Romain Boulandet

Variable acoustic properties can be obtained at the diaphragm of an electroacoustic transducer, with the help of very basic control strategies, among which is the simple electrical shunting of the transducer. These shunt techniques are compared to active a ...

Finite Element Model of Electrical Machines Coupled to the Grid Simulation Software

Jean-Jacques Simond, Mai Tu Xuan, Gilles Rosselet

Using a finite element (FE) model of the electrical machine in a grid solver enables us to take the machine nonlinearities into account with great precision in the simulation of a complete system. Three methods are usually used for linking the grid and FE ...

STUDY AND IMPLEMENTATION OF “DROOP CONTROL” METHODS FOR INTERFACING VOLTAGE SOURCE INVERTERS TO MINIGRID

Philippe Barrade

This contribution presents control methods for the regulation of the voltage and the frequency on AC minigrids, fed by voltage source inverters (VSI). In order to avoid a complex communication network for the synchronization of the various VSI on a minigri ...
