Abstract
The main barriers in the widespread adoption of electric vehicles (EVs) include limited autonomy, high up-front cost, low availability of charging infrastructure, and long charging time. Wide bandgap (WBG) semiconductors are key industry players in the electronics circuit design because they are advantageous in terms of high operating temperature, high efficiency, and low volume and weight. The WBG devices improve power density and allow power electronics (PE) circuits to reach operating points and temperatures that have not been considered before. Currently, SiC and GaN are the most viable WBG semiconductor candidates to replace Si-based devices. However, the cost, packaging limitations, reliability, safety, low manufacturing, and demand level of WBGs are issues that should be addressed; the integration of these devices into the automotive power electronic (APE) systems can then successfully be realized. This paper presents an industrial oriented overview of WBG power semiconductors including their advantages, recent progress, challenges, and development partnerships.

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
