Abstract
The aim of this work is to investigate the 3 rd quadrant safe operating area (SOA) of different voltage class SiC MOSFETs under surge current conditions depending on the gate-source voltage. The extent to which an applied gate-source voltage can influence the surge current capability was investigated. For 650 V and 1.2 kV voltage class devices, surge current capability was higher with channel-on mode. However, this behavior was vice-versa for 2 kV and 3.3 kV devices. In this investigation, during the surge current event, the gate-source voltage was switched between different values to optimize the resulting voltage drop. This method can reduce power dissipation during a surge current event, especially for high voltage class SiC MOSFETs.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
