Title (EN) PULSE WIDTH MODULATION INTERLEAVING
(FR) ENTRELACEMENT À MODULATION D'IMPULSIONS EN DURÉE
Abstract:
(EN) A pulse width modulation (PWM) interleaving system is provided. The PWM interleaving system includes active harmonic filters (AHFs). The AHFs are disposed in parallel with each other and with a load. The AHFs are electrically coupled to a common coupling point that is electrically interposed between a grid and the load. The AHFs are configured to affect, by PWM, a characteristic of current flowing between the grid and the load. The PWM interleaving system further includes a controller operably coupled to the AHFs and configured to synchronize the PWMs of the AHFs to thereby cancel ripple currents propagating towards the grid.
(FR) L'invention concerne un système d'entrelacement à modulation d'impulsions en durée (PWM). Le système d'entrelacement à PWM comprend des filtres harmoniques actifs (AHF). Les AHF sont disposés en parallèle les uns par rapport aux autres et en présence d'une charge. Les AHF sont couplés électriquement à un point de couplage commun, qui est interposé électriquement entre une grille et la charge. Les AHF sont conçus pour affecter, par PWM, une caractéristique de courant circulant entre la grille et la charge. Le système d'entrelacement PWM comprend en outre un dispositif de commande, couplé fonctionnellement aux AHF et configuré pour synchroniser les PWM des AHF, afin d'annuler ainsi des courants d'ondulation se propageant vers la grille.
