In this paper, a Liquid Nitrogen (LN2) cooled Gallium Nitride (GaN) Cryogenic Full Bridge (CFB) is presented as part of a Dual Active Bridge (DAB) for use in a hybrid Liquid Hydrogen (LH2) High Temperature Superconductor (HTS) transmission line. The concept of a 20 kW DAB with cryogenic parts is outlined and the design of the CFB as one of the cryogenic parts is presented. Furthermore, the construction of a cryogenic test bench is described which is used to validate the functionality of the CFB and to characterize it. Finally, the first measurements of the prototype down to 82 Kelvin are presented, which confirm the increased efficiency of the GaN semiconductors at cryogenic temperatures.

This paper introduces a multifunctional converter platform rated at 30kW. Individual units allow research
on advanced grid-connected converter control, while their interconnection enables isolated microgrid
investigations. The standardized and modular design allows simple reconfiguration of the system
for different setups, for which multiple measurements are presented.

This paper introduces a fully automated test bench for −75 °C up to 160 °C static and dynamic semiconductor characterization. First measurements performed with a 1.2 kV, 200 A Si-IGBT module and a 1.2 kV, 250 A SiC-MOSFET module show better semiconductor performance at lower temperatures compared to the conventional high temperature operation.
