Investigation and Reduction of Common Mode Current in Center-Tapped Transformer of LLC Resonant Converters
Bibliographic record
Abstract
This paper investigates the effects of resonant tank arrangements on the common mode (CM) noise current. CM noise reduction methods with symmetrical transformer winding structure and split resonant tank are proposed for full bridge (FB) LLC converters. For half bridge (HB) LLC converters, CM noise cancellation capacitor <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$C_{can}$</tex> is proposed to fully cancel the CM noise current flowing through the transformer. The corresponding extraction and calculation techniques of <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$C_{can}$</tex> are provided. Both techniques are lossless and easy to implement. The capabilities and excellence of aforementioned methods are verified by experiments.

How this classification was reachedexpand
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.
