Abstract
Abstract 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.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
154 words
An arrangement comprising: first and second three phase converter bridges adapted to be connected to respective converter transformers the first bridge including valves which are arranged successively and separately as to phase and all of which are further arranged so as to lie one on top of the other to form a first tower-like structure; the second bridge including valves arranged successively and separately as to phase and all of which are further arranged so as to lie one on top of the other to form a second tower-like structure; the first tower-like structure being arranged on top of the second tower-like structure to form a single tower-like assembly; the first bridge having DC and AC terminals arranged on one side of said assembly; the second bridge having DC and AC terminals arranged on the other side of said assembly; and a DC line connecting the DC terminals of said first and second bridges.
