SINAMICS G150
Engineering Information

Brief overview of SINAMICS G150 parallel converters with production date up to autumn 2007

The following is a short overview of the permissible transformer-converter-motor combinations with SINAMICS G150
parallel converters.
6-pulse configuration
Line reactors required
Symmetrical power cabling
DC links of the two parallel-
connected power units are not
coupled.
The outputs of the two parallel-
connected power units are
connected to a motor with separate
winding systems.
Symmetrical power cabling
Asynchronous motor with two
separate winding systems
Control by SVM + PEM
Maximum motor voltage related to
the line voltage: 97 %
