Title
(EN) MULTI-PHASE MOTOR/GENERATOR SYSTEM WITH HARMONIC INJECTION
(FR) SYSTÈME MOTEUR/GÉNÉRATEUR MULTIPHASE À INJECTION D'HARMONIQUE
Abstract
(EN)
A system includes a motor having a plurality of windings, a rotor and a stator magnetically coupled to the rotor, a plurality of power inverters connected to respective windings, wherein the plurality of power inverters is configured to control currents of the plurality of windings, and a controller configured to determine an injection ratio of a high-order harmonic component to a fundamental component based on a performance index, and wherein the injection ratio for a magnetizing component is different from the injection ratio for a torque component at a same harmonic frequency.
(FR)
L'invention concerne un système comprenant un moteur comportant une pluralité d'enroulements, un rotor et un stator couplé magnétiquement au rotor, une pluralité d'onduleurs de puissance connectés à des enroulements respectifs, les onduleurs de la pluralité d'onduleurs de puissance étant conçus pour commander des courants de la pluralité d'enroulements, et un dispositif de commande conçu pour déterminer un rapport d'injection d'une composante harmonique d'ordre élevé à une composante fondamentale sur la base d'un indice de performance, et le rapport d'injection d'une composante de magnétisation étant différent du rapport d'injection d'une composante de couple à une même fréquence harmonique.
