PEL Research Interests
The research interests of the Power Electronics Laboratory are in the broad area of the Electrical Energy Generation, Conversion and Storage. In particular, we are interested into High Power Electronics Technologies for Medium Voltage applications, those operating with voltages in kV range, currents in kA range and powers in MW range. Power Electronics is one of the key-enabling technologies for the future energy systems, as it offers unprecedented flexibility for the integration and control of various electrical sources, storage elements or loads into the grid. This is equally valid for the present-day AC grids as well as for emerging concepts of DC grids, or inevitable mix of both in the near future.
To achieve controllable, reliable and efficient electrical energy conversion by means of advanced power electronic converters, we optimally use, but also influence and drive forward, advancements in different areas. These multidisciplinary considerations include: power semiconductors (e.g. Si, SiC, GaN), passive components (e.g. magnetics), insulation materials, mathematical modeling, simulations and optimization of power electronic systems, advanced control methods, etc.
