A 100 kW 1.2 kV 20 kHz DC-DC converter prototype based on the Dual Active Bridge topology
This article presents the design, the fabrication, and the test of an isolated DC-DC converter for renewable energy applications. The converter is based on the Dual Active Bridge topology and uses silicon carbide power semiconductors and a medium frequency transformer. The design process covers hardware ranging from the semiconductor die to the complete power converter. For the control, a rapid prototyping approach was used. The experimental validation of the 100 kW prototype is presented.
Optimal sizing of a power electronic traction transformer for railway applications
This paper presents a methodology to optimize the sizing of such power converters in order to compare different topologies for a given application. The proposed procedure maximises the efficiency of the converter under a limited volume.

Uncertainty Quantification for the Eulerian-Lagrangian simulation of evaporating sprays
Evaporating sprays can be almost routinely simulated using an Eulerian-Lagrangian approach which relies on a RANS modeling of the continuous phase and a Lagrangian description of the discrete phase, including a turbulent dispersion model to express the effect of turbulent fluctuations within the carrier phase on the spray particles and an evaporation model for the spray droplets.
An injection molding press for our Chemistry & Materials test platform
With a new semi-automatic injection mixer and an injection molding press, the material characterization and the processing of our samples will take less time – close to industrial production thanks to the Automatic Pressure Gelation (APG) method.
