Overview of SINAMICS G150 parallel converters

The following is a brief overview of the permissible transformer-converter-motor combinations for SINAMICS G150
parallel converters.
6-pulse configuration
Line reactors essential;
Symmetrical power cabling
DC links of the parallel-
connected power units are
coupled
Three-phase motor with
separate windings
No decoupling measures
required at the converter
output if the number of
winding systems exactly
matches the number of
inverters.
Otherwise:
Note specifications for
minimum cable length or
use motor reactors or filters.
Note specifications for
symmetrical power cabling
Control by SVM + PEM
Maximum motor voltage
related to the line voltage
97 %
