Properties of Twelve-Pulse Rectifier with Short-Circuit Diodes
Abstract
This paper deals with simulation andexperimental efforts verifying influence of short-circuits of
semiconductor diodes on subsequent action of twelve-pulse
traction rectifier in traction power stations (3kV DC) of the
Czech railway. A computer model of a traction power
station, results and conclusion of research are described. To
verify relevance of results obtained from simulations
a measurement on a small laboratory model of twelve-pulse
rectifier was performed. These results are part of this paper
as well. Short-circuits are always examined using simple and
multiple commutation of diodes.
