An In-Depth Analysis of Power-System-in-Inductor (PSI<sup>2</sup>) Technology for Power Module Packaging
Bibliographic record
Abstract
This paper provides a thorough analysis of the power-system-in-inductor (PSI2) packaging for power modules through FEA simulation and experimentation of electrical and thermal performance. To sufficiently analyze the PSI2packaging, all tests conducted compare performance of PSI2to conventional plastic epoxy packaging using identical buck power modules. PSI2uses magnetic material as both the power module packaging and magnetic inductor core to increase inductor winding size and thermal conductivity of the package. In experimental testing the PSI2package achieves 2.82% greater efficiency, 0.48W less loss, 23.9°C lower top temperature, and 3.5°C lower bottom temperature at full load compared to the plastic package. Constant loss experimentation reveals approximately one third of the surface temperature difference is the result of the PSI2improved thermal conductivity at full load.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
