TL;DR: In this paper, a detailed analysis on the observed streamer characteristics of PEEK (polyetheretherketone) surface in nitrogen at atmospheric pressure driven by positive repetitive pulse voltage was presented.

TL;DR: In this article , the correlation between the thermal contact resistance and surface roughness characteristics of the contact interface in the press-pack insulated-gate bipolar transistor (PP-IGBT) modules during power cycling was studied by experimental measurements and finite-element (FE) simulation-based factorial design analysis.

TL;DR: In this article, the authors investigated the impact of the boil-induced bubble flow on the partial discharge (PD) and found that the heat induced fluid affects the density of dielectric liquid and ionization coefficient of the discharge environment, which reduces PD frequency.

TL;DR: In this paper , the authors proposed a high-voltage packaging method for >15-kV SiC power devices by designing an optimized stacked direct bond copper (DBC) substrate with a copper ring and a field-dependent conductivity (FDC) encapsulation using SiC as the filler.

TL;DR: In this article, the detailed characteristics of PETT oscillation, i.e., oscillation frequency, duration time, and oscillation peak, in high-voltage IGBT devices are systematically investigated by experiments.
