摘要：A synchronisation system (28) for at least two pul-width modulated electrical traction converters (14a, 14d) compris a first controller (18a) adapted for switching a first traction converter (14a) with pul width modulation bad on a first carrier signal (32a); a cond controller (18d) adapted for switching a cond traction converter (14d) with pul width modulation bad on a cond carrier signal (32b); and an electrical line (22) for transmitting a synchronisation signal (24) as electrical signal between the first controller (18a) and the cond controller (18d); wherein the first controller (18a) is adapted for generating the synchronisation signal (24) bad on a timing of the first carrier signal (32a); wherein the cond controller (18d) is adapted for determining a carrier shift of the cond carrier signal (32b) with respect to the first carrier signal (32a) bad on the synchronisation signal (24a).
