Abstract

fetched live from OpenAlex

This work presents an intelligent driver IC for 400 V GaN-based Power Factor Correction (PFC) applications. The targeted power level of the converter is 100 W, with a switching frequency above 500 kHz. The IC was implemented in a 140 nm automotive BCD SOI process, while the GaN HEMT and Schottky diode were optimized in a Si-fab compatible GaN-on-Si process. A low-R <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">on</sub> DMOS is integrated in the driver IC to achieve high-speed cascode switching operation. The chip also features a novel dual-mode drive scheme with monolithic negative drive voltage capability and programmable slew rate, as well as a digital peak current-mode controller. Advanced digital PFC control schemes can therefore be implemented, while EMC performance and efficiency can be optimized through active slope control.

Full frame distilled prediction

Teacher imitation

Not 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.
