Title (EN) SYSTEMS AND METHODS FOR REDUCING THE MAGNITUDE OF HARMONICS PRODUCED BY A POWER INVERTER
(FR) SYSTEMES ET PROCEDES POUR LA REDUCTION DE L'AMPLITUDE DES HARMONIQUES PRODUITES PAR UN CONVERTISSEUR CONTINU-ALTERNATIF
Abstract: front page image
(EN)Systems and methods for operating a pulse width modulation (PWM) circuit in a direct current (DC) to alternating current (AC) power inverter to reduce the magnitude of harmonics. The PWM circuit operates using a reference signal having an irregular period. This irregular periodicity may comprise a sequence of periods uniformly distributed about a target period.
(FR)La présente invention a trait à des systèmes et des procédés pour le fonctionnement d'un circuit de modulation d'impulsions en durée dans un convertisseur de courant continu en courant alternatif en vue de réduire l'amplitude des harmoniques. Le circuit de modulation d'impulsions en durée fonctionne au moyen d'un signal de référence ayant une période irrégulière. La périodicité irrégulière peut comprendre une séquence de périodes uniformément réparties autour d'une période cible.
