Thermal Analysis of Power Module Packaging Using Power-System-in-Inductor (PSI<sup>2</sup>) Technology
Bibliographic record
Abstract
This paper presents a thermal analysis of the power-system-in-inductor (PSI2) packaging for 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. Two identical buck power modules are designed using the new PSI2package and traditional plastic packaging. A thermal equivalent circuit (TEC) model is developed to estimate case and junction temperatures based on estimated loss data. FEA simulation is used to validate the TEC and predict the experimental results. Experimentation is conducted at constant load and loss to compare thermal performance of PSI2to conventional plastic epoxy packaging using identical buck power modules. In experimental testing, constant loss experimentation reveals an 8.6 C surface temperature decrease for the PSI2package. Therefore, approximately 33% of the PSI2temperature decrease is attributed to improved package thermal performance.

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.
