Abstract
Novel active auxiliary circuits that allow the power switch in single-switch, pulse-width-modulated (PWM) converters to operate with zero-voltage switching (ZVS) are proposed in this paper. The main feature of these circuits is that the auxiliary switch can operate with a zero-current switching turn-on and turn-off without increasing the peak current stresses of the main switch. In this paper, the operation of active auxiliary circuits in general is reviewed, and a systematic method for synthesizing auxiliary circuits belonging to the new family is presented and demonstrated with several examples. Several new auxiliary circuits are presented, and the operation of one of the new circuits is briefly explained. A general set of guidelines for the design of auxiliary circuits belonging to the new family is presented. The feasibility of the new family of circuits is confirmed by experimental results obtained from a 500 W, 100 kHz zero-voltage-transition (ZVT)-PWM boost converter prototype implemented with an example auxiliary 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
