Title (EN) SYNCHRONISING TRACTION CONVERTERS
(FR) SYNCHRONISATION DE CONVERTISSEURS DE TRACTION
Abstract:
(EN) A synchronisation system (28) for at least two pulse-width modulated electrical traction converters (14a, 14d) comprises a first controller (18a) adapted for switching a first traction converter (14a) with pulse width modulation based on a first carrier signal (32a); a second controller (18d) adapted for switching a second traction converter (14d) with pulse width modulation based on a second carrier signal (32b); and an electrical line (22) for transmitting a synchronisation signal (24) as electrical signal between the first controller (18a) and the second controller (18d); wherein the first controller (18a) is adapted for generating the synchronisation signal (24) based on a timing of the first carrier signal (32a); wherein the second controller (18d) is adapted for determining a carrier shift of the second carrier signal (32b) with respect to the first carrier signal (32a) based on the synchronisation signal (24a).
(FR) La présente invention porte sur un système de synchronisation (28) pour au moins deux convertisseurs de traction électriques à modulation de largeur d'impulsion (14a, 14d) qui comprend un premier dispositif de commande (18a) conçu pour commuter un premier convertisseur de traction (14a) avec modulation de largeur d'impulsion sur la base d'un premier signal de porteuse (32a) ; un second dispositif de commande (18d) conçu pour commuter un second convertisseur de traction (14d) avec modulation de largeur d'impulsion sur la base d'un second signal de porteuse (32b) ; et une ligne électrique (22) destinée à émettre un signal de synchronisation (24) en tant que signal électrique entre le premier dispositif de commande (18a) et le second dispositif de commande (18d) ; le premier dispositif de commande (18a) étant conçu pour générer le signal de synchronisation (24) sur la base d'une synchronisation du premier signal de porteuse (32a) ; le second dispositif de commande (18d) étant conçu pour déterminer un décalage de porteuse du second signal de porteuse (32b) par rapport au premier signal de porteuse (32a) sur la base du signal de synchronisation (24a).
