Leo Lorenz, ECPE, D
 | | Prof.Dr.Leo Lorenz
received the Dipl. Ing. Degree from TU-Berlin and the Dr.-Ing. Degree
from the University of Munich, Germany in 1976 and 1984 respectively.
From 1976 till 1980 he was with AEG, R&D-center for Power
Electronics- in Berlin. In 1984 he joined Siemens Semiconductor Division
which became Infineon Technologies AG in 1999. Since this time he has
been working on Power Semiconductor & Power IC’s in different
functions and responsibilities. As a senior principal he was responsible
for system engineering of industrial technologies and for the time
being located in Munich. He published over 300 technical papers and has
many patents in these fields. In 2001 he was nominated to become
Professor for System Integration at the University of Ilmenau (Germany).
He is the president of the ECPE (European Center of Power Electronics),
an IEEE Fellow, a member of German Academy of Science and received
several best paper and innovation awards. |

Description
Course Target:This
course is targeting R&D engineers from Industry and Academia
involved in development, design and optimization of power electronic
converters.
The Megatrends of our society such as Energy
Efficiency, E-Mobility, Renewable Energies and SMART Grid are asking for
Smart Power Electronic Solutions. Power Electronics is the technology
associated with the efficient power conversion, precise control and
conditioning of electric energy from the source up to the load.
Power
Semiconductor devices are an enabling technology to meet these
requirements. The major electrical and thermal improvement of the new
generation of power devices is coming from the overall silicon chip
utilization. Based on this idea the device technology development
follows a chip horizontal optimization e.g. high cell densities, new
trench gate structures and a vertical optimization to minimize drift
layer and reduce the On-State losses significantly. This power device
mainstream technology development is applied to all device types such as
the IGBT, Fast Recovery Diode, Super Junction Transistor and low
Voltage MOSFET.
The reliability and ruggedness of these new power
semiconductors is driven by an advanced chip interfacing and packaging
technology. For ultra high efficiency and ultra high power density fast
switching devices have been developed. However it has to be considered
that the application engineer is faced with new challenges of how to
manage all the parasitics, thermal management and circuit set up.
