Abstract
This paper presents a new non-isolated asymmetrical buck converter. The transformer is used to extend the extremely low duty-cycle of a conventional buck converter. The turn-off loss can be significantly reduced due to the extension of duty-cycle and there is no turn-on loss owing to zero-voltage turn-on condition. At the same time, the voltage stress over the synchronous rectifier (SR) MOSFETs is also reduced. Therefore, the reverse recovery losses of the body diode can also be reduced. Furthermore, MOSFETs with the lower voltage rating and lower R <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">ds(on)</sub> can be used to reduce the conduction loss further. To further reduce the turn-off loss above the switching frequency of 1MHz, current-source gate driver can be also applied to this topology. A prototype at switching frequency of 1MHz was implemented and the preliminary experimental results verify the functionality of the new circuit.

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
