Areas of Research: Energy Research, Information Technology
Thematic Priority: Semiconductors

Field of Work

The research interests of Prof. Kallfass and his team are focused on integrated semiconductor circuits and systems for power electronics and high-frequency electronics. Voltage transformers based on modern semiconductor technologies are now being used in applications for electric drives, power supply units and converters for renewable energies. Another of the institute’s research focus areas is the development of radio communication systems with high data rates for the access range with broadband internet. Broadband transmitters and receivers in the millimeter wave frequency range are developed at the Institute of Robust Power Semiconductor Systems for this purpose.
