Title: HIGH VOLTAGE POWER CONVERTER SYSTEM
Abstract:
The invention relates to a high voltage power converter system which is usable, for example, in a drive system (1) for rail vehicles. The current rectifier system (2) comprises a plurality of partial rectifier systems (2,1 to 2.n) for the supply of several motors of a user system (3). A high a.c. voltage (5.1) is supplied in a series circuit of the partial rectifier systems (2.1 to 2.n), thus avoiding the use of an otherwise necessary mains-side transformer. The rectifier system (2) can be relatively simply designed as a multiple system and even to supply a d.c. voltage (5.2).
