Abstract
This paper presents a zero-voltage-transition (ZVT) boost converter using a soft switching auxiliary circuit. The improvement over existing topologies lies in the structure and position of the auxiliary circuit capacitors and the subsequent reduction in the main switch resonant current. This converter has the following features: (1) soft switching of the main switch and boost diode under all operating conditions; (2) reduced auxiliary circuit losses due to soft switching of the auxiliary switch; (3) feedforward of a part of the auxiliary circuit energy to the output. The operation of this converter is analyzed and characteristic curves are presented, which help in the design process. Experimental results from a 250 W, 127 Volt input laboratory prototype switching at 100 kHz are shown which verify the advantages of this topology.

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
