Microscopic Stress Analysis of Silicon Carbide Devices Under Overcurrent Conditions in DC Solid‐State Circuit Breakers

open access: yesIET Smart Energy Systems, EarlyView.
A coupled Saber–TCAD–thermo‐mechanical simulation framework is proposed to evaluate microscopic stresses in SiC MOSFETs under overcurrent operation. Ultrahigh gate‐voltage driving reduces thermal and mechanical stress but increases gate oxide electric‐field stress, revealing a reliability tradeoff for DC solid‐state circuit breakers.

Image Encoding With Blipped Gradients in an Echo Train

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 5, Page 2530-2538, November 2026.
ABSTRACT Purpose An MRI scanner was designed and built to encode k‐space points in the spin echoes occurring between 180∘ pulses in an echo train by using blipped B0 gradient pulses applied just prior to those spin echoes. Methods The proposed MRI scanner is a modification of an original design that used TRansmit Array Spatial Encoding (TRASE), a built‐
