Title: Control strategy allowing losses to be minimised in an asynchronous machine
Inventor: EL FADILI ABDERRAHIM
IPC: H02P23/02
Filed: 2021-01-17
Abstract: Asynchronous machines occupy a very important place in industry and transportation. They are appreciated for their robustness, low purchase cost and low maintenance cost (because they do not comprise any mechanical collector). Energy efficiency is maximal provided that the machine always operates in the vicinity of its nominal point. In practice, this is not the case because the load of the machine is generally variable or the machine is oversized. In the presence of low loads, the operating point drops below the nominal value causing energy to be needlessly stored in the inductors of the stator, which decreases the efficiency of the machine. To overcome the aforementioned drawbacks, the invention proposes a strategy for controlling the inverters (4) feeding the asynchronous machine (1) in order to decrease their consumed losses. The control strategy for this speed variator for the asynchronous machine allows losses to be minimised in the asynchronous machine regardless of its speed and/or its mechanical load. This control strategy computes the stator feed voltage (V), in real time, of the asynchronous machine as a function of the feed frequency (f) and the current (I) absorbed by the asynchronous machine (1), according to the law illustrated by (7) and detailed in equations (1) to (3).

Title: Haut-parleur multimedia a dipole

IPC: H04R1/32
Filed: 2006-01-26
Abstract: L'invention concerne un haut-parleur multimédia à dipôle qui est un haut-parleur à dipôle dans la gamme film destiné à être utilisé en tant que haut-parleur d'ordinateur ou haut-parleur multimédia. Le haut-parleur à dipôle (4) est constitué d'un panneau plat (5) dans lequel est monté un haut-parleur dans la gamme film (6), mais le haut-parleur à dipôle (4) peut être également un haut-parleur de type plat et plan. Le haut-parleur à dipôle (4) est placé à un angle saillant (aigu) b par rapport à la surface de travail (7). Cet angle b est égal à l'angle saillant (aigu) que fait le plan imaginaire dans lequel réside l'oreille de l'auditeur ou le microphone (8) vers le plan de la surface de travail (ou du bureau), l'intersection de ces trois plans étant une droite commune (9). Du fait que le haut-parleur à dipôle ne rayonne pas dans le plan imaginaire dans lequel réside son panneau, aucun signal sonore réfléchi provenant du bureau n'atteint l'auditeur (8). Ceci signifie que la réponse en fréquence de l'invention, mesurée au niveau du point de l'auditeur, sera plate et ne dépendra pas du fait que le haut-parleur est placé sur un bureau ou non. Les sons en dessous de la fréquence limite inférieure du haut-parleur à dipôle devront être reproduits par un haut-parleur de basse séparé (un caisson de basse) par l'intermédiaire d'un répartiteur adéquat.
