Abstract
Static frequency changers (SFCs) typically use a rectifier-inverter combination with a passive LC filter as the intermediate DC link. This class of SFCs does not allow sustained regeneration and requires a bulky DC filter. A recently proposed alternative, based on the synchronous energy transfer principles, has successfully solved the problems of power regeneration, but still requires a DC side filter. Moreover, it is very susceptible to input AC line unbalances. A class of compact regenerative SFCs, which do not require a DC filter, are insensitive to input unbalances, and have a very rugged power and control circuit structure. PWM pattern generation on the inverter side is based on output current control. Design and implementation considerations are discussed. Simulation and experimental results confirm the feasibility and predicted performance of the proposed class of converter circuits.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

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
