Title
(EN) DEVICE FOR CONTROLLING AN INVERTER
(FR) DISPOSITIF DE COMMANDE D'UN ONDULEUR
Abstract
(EN)
In a system with an inverter (1) associated with an electrical machine (2), a control operation (9) involves a variable-frequency pulse width modulation method in order to optimize efficiency of the system. According to the invention, the values of the current chopping frequency are limited depending on other criteria, which may be chosen from among noise or torque deformations of the machine (2) or the electrical loading inflicted on a capacitor (8) of the filter stage (4).
(FR)
Dans un système à onduleur (1) associé à une machine électrique (2), une commande (9) implique un procédé de modulation de largeurs d'impulsions avec une fréquence variable pour optimiser un rendement du système. Selon l'invention, les valeurs de la fréquence de découpage du courant sont limitées en fonction d'autres critères, parmi lesquels on peut choisir le bruit ou les déformations de couple de la machine (2) ou les sollicitations électriques infligées à un condensateur (8) de l'étage de filtrage (4).
