Abstract
Wide-Bandgap devices are pushing the boundaries of switching frequencies, power densities, and efficiencies of modern power converters. To utilize the full potential of these devices, the parasitic elements formed by the printed circuit board (PCB) layout requires special attention. This work introduces a novel approach, that helps to reduce the parasitic inductance of the commutation loop in a half-bridge topology with surface-mount power devices. The approach uses multiple PCB layers for enhanced current distribution and magnetic cancellation, which results in low inductance designs with less sensitivity to the geometric parameters of the PCB design. The approach is validated with simulation results via a Finite Element Analysis (FEA) as well as with experiments. The results show a promising reduction in inductance and geometric sensitivity compared to the conventional solution.

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
