Design and Realization of a Lightweight Cryogenic DC-DC Converter for Airborne Applications
This thesis investigates the gravimetric power density limits of a buck-boost dc-dc converter at cryogenic temperatures through multi-objective optimization. Initially, the behavior of power electronic components at cryogenic temperatures is studied and then implemented in a multi-objective optimization framework. Finally, a 15-kW prototype shall be built to validate the results.

Realization and Characterization of Transcutaneous Energy Transfer System
Percutaneous drivelines are the major cause for infections after implanting a mechanical circulatory support system (e.g., a ventricular assist device or a total artificial heart). Inductive power transfer systems are a promising alternative. The main challenges are the heating of the tissue and the limited allowed power dissipation for implanted power electronics.
