“…All these converters will be installed underground; this installation leads to the necessity for reduced volume and high efficiency for the power converters.This paper presents a novel four-quadrant topology. This DC-AC-DC topology is fully reversible and the soft-commutation is achieved in all the switches over the full range of operation. …”

“…We also put forward a physical explanation of the observed degradation caused by proton irradiation; in particular, the electron drift velocity in the 2DEG channel at high electric fields appears to decrease due to a radiation-induced increase in phonon relaxation rate. Finally, an AC/DC LED power supply with current control using GaN HD-GITs is proposed for the new luminaires of CERN tunnels, meeting the requirements in terms of radiation hardness and light quality.…”
