IPEC is focused on High Power Converter
Systems for application in
•
Energy transmission and Energy
distribution
•
(Wind power, solar power, solar-
thermic power, DC-Super grid)
•
Large electric drives
(Traction,electric ships, electric aircraft)
•
Electric vehicle drives
(LEV, electric passenger cars)
and new Converter architectures enabling
•
Modular, scalable hardware
•
Fault tolerant operation
•
Fully digital control and integrated
sensors
These systems are developed and investi-
gated thoroughly with respect to indus-
trial feasibility. The equipment at IPEC
includes laboratories for investigation of
High Power Converters up to 20kV in the
MW-Range and Electric Drives up to 1kV
in the 100kW-Range.
Advanced Multilevel-Converters for
High- and Medium-Voltage
High Voltage Direct Current Transmission
(HVDC) is becoming a key enabling tech-
nology for the integration of regenera-
tive sources into the grid. While the con-
ventional AC-Networks are getting more
and more inefficient or unstable under
the new conditons, an electronically
controlled DC-Grid will be extremely
valuable.
Advanced Multilevel-Converters are the
most promising systems for these
requirements. New concepts, suitable for
these applications, are developed at
IPEC (E.g.: Modular Multilevel Converter,
M2C). Research is concentrated on indus-
trial scalability, safety, fault tolerant op-
eration and the digital control system.
At the control side, the new systems of-
fer vastly extended degrees of freedom.
Therefore, many research projects are
focused on new digital control schemes,
for improved exploitation of these new
possibilities.
Large Drives with Medium-Voltage repre-
sent another important field for Modular
Multilevel Converters, applied e.g. for
industrial drives and electric Ships.
Ultra light converters for mobile
applications (MHF)
The successful development results of
Multilevel-Converter for the High Power
range has led to a significant extension
of research projects , focused on mobile
applications. In this area, industrial scal-
ability ,modularity of the hardware and
fault tolerant operation are very impor-
tant, too. Additionally, ultra light weight
and minimized space are essential points.
These requirements are best met by new
multilevel topologies, which allow for the
elimination of passive filters. New con-
verter topologies (MHF) enabling and
integrated contol and sensors are devel-
oped and investigated in several research
projects.
