12-pulse parallel connection of Basic Line Modules

With the 12-pulse variant of parallel connection, up to four Basic Line Modules on the line

side are supplied by one three-winding transformer. An even number of Basic Line Modules,

i.e two or four, must be divided equally between the two secondary windings. The Basic Line

Modules of both subsystems are controlled by a common Control Unit - even though the

input voltages are 30° out of phase.

There is also the redundant variant with which two BLMs in each case are controlled by one

Control Unit.
