Overview
SINAMICS SM150 in the IGCT version
Water-cooled, regenerative feedback SINAMICS SM150 con-
verters in the IGCT version are available as single or multi-motor
drives with the well-proven medium-voltage IGCT power semi-
conductors. With multi-motor drives, a common DC bus enables
the direct exchange of energy in generator and motor applica-
tions.
IGCT converters are available for the following voltage and
outputs:
The rated power in the specific application will depend on the
necessary load cycle.
Note:
For other technical requirements that have to be taken into con-
sideration (surge loads, operation at low frequencies, possibly
necessary derating for parallel circuit configurations, limits re-
garding the maximum permissible short-circuit current) please
contact your Siemens sales partner indicating the required
specifications.
Global use
SINAMICS SM150 converters in the IGCT version are manufac-
tured to international standards and regulations, making them
ideally suited for global use. These converters are also available
in ship-going form (meeting the requirements of all major
classification organizations).

Benefits
7
Compact design and highly flexible configuration ensures
easy plant integration
7
Simple operator control and monitoring from the user-friendly
operator panel
7
Simple and reliable operation through integrated maintenance
functions: The converter signals early on and automatically if
maintenance is required or components need to be replaced
7
High degree of ruggedness and reliability due to the use of
IGCT power semiconductors in the high power range and
fuseless design combined with an intelligent response to
external disturbances
7
Can be easily integrated into automation solutions as the
PROFIBUS interface is supplied as standard along with
various analog and digital interfaces
7
High level of service-friendliness through innovative power
unit design with compact phase modules and easy access to
all components
7
By appropriately engineering the drive system, reactive power
can be made available to other drives, therefore helping
ensure that the plant or system is cost effective.

Design
Active Line Modules and Motor Modules share an almost identi-
cal structure with both the single-motor and the multi-motor
drive. Phase modules in which IGCTs, diodes etc. are grouped
together in one compact system are used in both.
Single-motor drive
With a single-motor drive in the basic circuit, one Active Line
Module and one Motor Module are connected via a DC link.
For greater output ratings, two or three complete converter units
with isolated DC links are operated in parallel.
Multi-motor drive
With multi-motor drives, up to six power units are operated on the
common DC bus. In addition to the Active Line Module, four
Motor Modules with four motors can be operated on the common
DC bus where energy can be directly exchanged. In this case,
configurations are also possible with two Active Line Modules.
The converter consists of cabinet units for the Active Line
Module and for the Motor Module. One of three phase modules
and the control section in the Motor Module cabinet unit are
highlighted in the illustration.
