German to English translations [PRO] Tech/Engineering
German term or phrase:Wanderwellen, etc.
I would appreciate some help disentangling this sentence!
The text is about the use of frequency inverter-controlled drives in potentially explosive areas, and more specifically, voltage peaks and how to prevent them.
'Beim Einsatz von Frequenzumrichtern mit Spannungszwischenkreis treten durch die schnell schaltenden Wechselrichter-Endstufen sogenannte Wanderwellen in den langen Motorleitungen auf, die durch Multireflexionen an den Leitungsenden schwingende Impulsspannungen an den Motorklemmen hervorrufen.'
Explanation: Using frequency converters with intermediate voltage circuits, so called travelling waves are evoked in the long motor cables by the quickly switching inverters. These waves cause oscillating impulses at the terminals by multiple reflections.
pooh, what a sentence, I omitted 'Endstufe', its normally power amplifier, this doesn't seem to suit to this context, they obviously mean, that the inverters are the last components of the device before the signal is transmitted to the cables. I'm not 100% sure about the translation, because this is not my field
