Abstract
<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> In this paper, a new non-isolated full bridge (NFB) topology is introduced to solve the narrow duty cycle and hard switching problems of the Buck converter in low output voltage, high output current applications. In comparison to the Buck converter, it operates at a significantly wider duty cycle and can achieve zero voltage switching for the high side MOSFETs. The NFB significantly reduces the input peak current and transfers a portion of the primary side energy directly to the load thereby reducing the stress on the synchronous rectifiers and filter inductors. Using self-driven synchronous rectifiers, the body diode conduction loss is reduced since no dead time is required between the primary side MOSFETs and the synchronous rectifiers. Given these significant advantages, the NFB can achieve higher efficiency than a two and three phase interleaved Buck at the same power level. The efficiency gain enables the NFB to operate at a high switching frequency thereby enabling smaller output inductors to be used to achieve improved dynamic performance. </para>

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
