Abstract
Although the zero-voltage switched (ZVS) pulsewidth modulated (PWM) full-bridge (FB) converter can operate with soft-switching and fixed frequency control it loses its ZVS capability under light-load conditions. This paper examines the use of auxiliary circuits attached to the bottom switches of the standard ZVS-PWM-FB converter as a means of extending the ZVS range. The auxiliary circuits, each consisting of an active switch and passive components, operate for only a small portion of the switching cycle, and handle very little power. The basic operating principles of these type of modified ZVS-PWM-FB converters are explained in detail in the paper, and general guidelines for their design are given. A design procedure is derived and demonstrated on an example converter. The feasibility of this converter is shown with results obtained from an experimental prototype.

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
