Design
SINAMICS GM150 converters in the IGBT version are available
with a 12-pulse or 24-pulse Basic Line Module.
The 12-pulse version is standard for smaller output ratings with
voltages of 2.3 kV, 3.3 kV and 4.16 kV.
For higher output power ratings, two Basic Line Modules with
a common DC link or two Line Modules (24-pulse Basic Line
Modules) are connected in parallel.
The 24-pulse Basic Line Module is optionally available for
smaller output ratings with voltages of 2.3 kV, 3.3 kV and 4.16 kV.
HV-IGBT power semiconductors are used in the Motor Modules
– they are mounted on plug-in Power cards that are simple to
replace.
Both line and motor connections can be optionally realized from
underneath or above.
The converter cabinet unit consists of a section for the Basic
Line Module, a section for the Motor Module and the control
section.
