Spatial arrangement of the valves of a three-pulse converter system

摘要

A twelve pulse converter system is disclosed in which the two three-phase converter bridges forming the system are arranged one on top of the other in a single tower-like assembly and the valves of the bridges are disposed successively and separately as to phase. Additionally, the DC and AC terminals of one of the converter bridges are disposed on the one side of the tower-like assembly and the DC and AC terminals of the other of the converter bridges are disposed on the other side of the tower-like assembly, the DC terminals located on opposite sides being connected to each other by a DC lead.
