Abstract
A 1-/spl phi/ high-frequency transformer isolated AC-to-DC controlled rectifier with low line current harmonic distortion using a variable frequency controlled hybrid parallel-series resonant converter bridge is proposed. Operation with and without active line current waveshaping is presented. A state space analysis method is used to get various design curves and to predict theoretically the waveforms and line current harmonic distortion. By exercising active current control, power factor close to unity with low line current distortion is maintained for the entire range of operation in addition to zero voltage switching and reduced peak current stresses compared to parallel resonant converter. Simulation results obtained from the state space model, SPICE3 (without active control) and experimental results (rated at 150 W with and without active control) are given to verify the operation of the AC-to-DC converter.

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
