A new family of zero-voltage-transition PWM converters with dual active auxiliary circuits
Bibliographic record
Abstract
A new family of active auxiliary circuits that allow the power switch in single switch, pulse width modulated (PWM) converters to operate with zero voltage switching (ZVS) is proposed in this paper. The switch in an auxiliary circuit belonging to this family can operate with a zero current switching (ZCS) turn-on and turn-off without increasing the peak current stresses of the main switch. In the paper, the fundamental principles behind the proposed family of active auxiliary circuits are explained. Based on these principles, an example auxiliary circuit is systematically derived and presented along with several other auxiliary circuits of the new family. The operation of a boost converter operating with the example auxiliary circuit is described, and general guidelines for the design and implementation of auxiliary circuits belonging to the new family are given. The feasibility of the example auxiliary circuit is confirmed by experimental results obtained from a 500 W, 100 kHz boost converter laboratory 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
