University of rostock
The Institute of Electrical Power Engineer-
ing at the University of Rostock is engaged
in extensive research in the area of medi-
um and high power semiconductors and
their application in inverters for electrical
drives and energy transmission. An excel-
lent equipped laboratory with newest test
benches, measuring techniques and state-
of-the-art simulation tools offers research
on emerging topics like Silicon Carbide,
Reverse-Conducting IGBTs, multilevel in-
verters, HVDC grids and inverters, grid
stability and control and hybrid vehicles.
Currently fifteen scientific employees are
exploring exciting topics in the area of pow-
er electronics. Some research topics are:
•
Power Semiconductors: electrical and
thermal characterization of Reverse-
Conducting IGBTs, detailed analysis of
the switching behavior of IGBTs like
self-turn on/off, short-circuit behavior
of IGBTs and diodes especially in inverter
operation, switching behavior of Silicon
Carbide MOSFETs/JFETs and their appli-
cation in modules, lifetime estimation
in wind power applications, device
simulation
•
HV gate drive units: design of special
high-voltage (up to 6,5 kV) gate drive
units, advanced gate drives with FPGAs
for Reverse-Conducting IGBTs, gate drives
for improved short-circuit behavior
•
Multilevel/HVDC: hardware-based
inverter control with scaled low-voltage
test benches of multilevel inverters
(3L-(A/AA)NPC, 3L-T-Type, C5LC,
Hybrid 7L), modulation of modular
multilevel converters
•
Influence of inverters on the grid:
improved inverter control for offshore
grids, Fault Ride Through behavior
of wind generators with 50 kW test
bench, grid oscillations with electronic
loads, scaled low-voltage grid with
several wind generators and HVDCs
•
Automotive drive test bench: 400 V
hybrid test bench with dSpace engine/
inverter control and load machine,
48 V/15 kW test bench for mild hybrid
engines
•
Education and training of succeeding
electrical engineers (B.Sc., M.Sc., PhD)
