Brief Overview Of Sinamics G150 Parallel Converters With Production Date From Autumn 2007 - Siemens SINAMICS G130 Engineering Manual

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

The following is a short overview of the permissible transformer-converter-motor combinations for SINAMICS G150
parallel converters.
6-pulse configuration
Line reactors required;
Symmetrical power
cabling
DC links of the parallel-
connected power units
are 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 %
