Abstract
This paper introduces a novel one-step digital control technique that can dynamically optimize the dead-times for the turn-on and turn-off of the power MOSFETs in DC-DC converters. A NOR gate and a delay-line circuit are used to detect and measure the duration of the unwanted low-side MOSFET body-diode conduction. Based on this measurement, the optimum dead-time is calculated on-the-fly and the DPWM controller will respond immediately to maximize the conversion efficiency in the next switching cycle. This approach is well suited for digital IC implementation. Experimental results from a digitally controlled 6V to 1V, 10A synchronous buck converter verified the efficiency improvement and the practical implementation of the proposed one-step dead-time correction algorithm. This one-step dead-time correction can improve the converter's efficiency by 2 to 4%, depending on output current, output voltage and switching frequency.

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
