Siemens AG
Power electronics drive many of
todays and future products and
systems
Siemens is positioned at the leading edge
of technology and is with 80 billion rev-
enues and around 400.000 employees
one of the largest electric and electronic
companies worldwide. Power electronics
play an important role in all four sectors –
many products include such devices in all
voltage and power levels. Siemens has
intensive research programs in the field
of power electronic components itself
but especially in the field of their applica-
tion in products and systems. Internal
research as well as close research coop-
eration with universities is the base for
new technologies as part of new prod-
ucts and systems for demanding markets
and applications.
Improving public healthcare
Power electronics are an es-
sential part of many medical
equipment and systems of the
sector Healthcare. For example
by high speed dynamic control-
ling of the currents for gener-
ating high strength magnetic
fields inside magnetic reso-
nance imaging scanners (MRI).
More, more efficient and
more sustainable energy
For many years power electronics are
used in high power and high voltage
energy equipment – for instance thyris-
tors and IGBTs for high voltage DC trans-
mission (HVDC). The transformation of
todays grid to handle an ever increasing
amount of fluctuating renewable decen-
tral energy generation requires an effi-
cient transmission of electrical energy
locally as well as over wide distances. All
options and techniques to solve this have
as a common base the need for power
electronics to provide the necessary con-
trol of electrical energy transmission.
Modern cities and infrastructure
Reliability, safety, security and flexibil-
ity play an important role in medium and
low voltage power distribution, in urban
railway infrastructure as well as with in-
novative smart grid technologies. Urbani-
sation stands for a rapid growth of cities
to mega cities and this drives the need
for power electronic equipment to dis-
tribute and control electrical energy flows
in a highly densified urban environment.
Automation and drives technology
Automation and drive products were
the main application of power electronics
for many decades. More or less every
factory and plant use such equipment.
New applications with very dynamic
growth emerge with small and big scale
regenerative power generation such as
photo voltaic and wind turbines and the
electrical passenger car.
