Cabinet of Sinamics SM150
The Sinamics SM150 medium-voltage drive is
used for sophisticated single- and multi-motor
drive applications. It distinguishes itself as
a result of its high dynamic performance with
maximum control precision. Supporting a drive
output range extending from approximately 2,500
to 30,000 kVA, the Sinamics SM150 system is based
on water-cooled, three-level converters designed
around Integrated Gate Commutated Thyristors
(IGCT) with a voltage source link and Active
Front End (AFE). It is suitable for four-quadrant
operation with active regenerative feedback into
the line supply.
Compared to the cycloconverter, the SM150 can be
operated with an adjustable line power factor,
which means that this converter type is not producing
any reactive power if it is operated with a line
power factor of 1.
