Power Cycle Modulation Control of LLC Resonant Converters for Wide Voltage Gain Range Applications
Bibliographic record
Abstract
This paper proposes Power Cycle Modulation (PCM) control method of LLC converters for wide voltage gain range applications. Instead of switching frequency modulation, the proposed PCM method operates the LLC converter according to a control period comprising an on cycle operation mode for a duration <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$T_{on}$</tex> and an off cycle operation mode for a duration <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\boldsymbol{T}_{off}$</tex> . <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\boldsymbol{T}_{on}, \boldsymbol{T}_{off}$</tex> and the optimal switching frequency during <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$T_{on}$</tex> are adjusted based on the sensed input and output voltages. Optimal switching pulse pattern can be maintained under the low output voltage and high input voltage conditions, which ensures the high efficiency. A 65W prototype is built to verify the feasibility and validity of the proposed control method.

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.
