DOI: 10.1109/tec.2020.3037244
Abstract: In multi-MW three-level neutral point clamped back-to-back (3L-NPC) power converters, power semiconductor devices are considered as most vulnerable components due to its thermo-mechanical fatigue stress. Particularly, rotor side converter (RSC) in doubly fed induction machine… read more here.

DOI: 10.1109/tia.2018.2809543
Abstract: The new packaging technologies used for gallium nitride (GaN) devices avoid wire bonds and leads in order to completely utilize their switching performance. This also means that thermomechanical fatigue that used to exist within the… read more here.
