[Sound] BR 146.2 //Bombardier Traxx//IGBT-inveter//RE 19531

[@robertmwamba7971]

It sounds a bit like NJ Transit ALP-46s

[@Dan-sq4xk]

Well it is literally a replica of a DB BR 146. Built by Bombardier in Germany but for use on American railroads.

[@telefondose2803]

@@Dan-sq4xk Actually it's a replica of DB BR101, not BR146 which is derived from BR101 as well. And BR101 is from AEG/ADtranz, not Bombardier luckily.

[@JaredRouse8465]

Maybe their related in some way.

[@rinkito2002]

Hört sich wie GTO an.

[@telefondose2803]

GTO cannot switch fast enough for Frequency Modulation (going from 1:02).

@@telefondose2803 the ET 423 series 1 also has that sound even though it relies on a GTO VVVF

[@telefondose2803]

@@or2kr Yes I am mistaken. Thank you for pointing out.

[@velarod3961]

@@or2kr While the 423 might have a similar sound, it doesn't switch that fast.

@@telefondose2803 eingesetzt wird die Direkte Selbstregelung, dabei ist die Pulsfrequenz in einem definierten Rahmen zufällig variabel. Für Phasenbausteine mit GTO-Thyristoren lassen sich diese Parameter, genau wie die Trägerfrequenz im Flash oder ROM des DSPs setzen.
