Abstract
With the development of new power systems, IGBT has been more widely used in rail transit, new energy vehicles, photovoltaic power generation and other fields. The high efficiency and reliability of electrical insulation have received widespread attention. In this paper, in order to solve the problem of defects in the use of IGBT chips in the electrostatic field, the IGBT electrostatic field simulation model was constructed in COMSOL through the finite element method, and the results of different defects were explored through the electric field distributions presented in the simulation results. It is concluded that voids, bubbles, and metal protrusion defects all have an effect on the electric field distribution at the triple bonding point, and the field strength inside the defects is greater. Meanwhile, the corresponding data base is also provided for the device design of IGBT.

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
