An Inductive Power Transfer System using Soft-Switched AC/AC Active-Clamped Half-Bridge Converter with Predictive Dead-Beat Grid Current Control
Bibliographic record
Abstract
In this paper, a dead-beat control-based AC/AC active-clamped half-bridge (HB) converter feeding inductive wireless charging system is presented. It offers some advantages of a low component count, high efficiency, reliability, cost-effectiveness, and unity power factor. The system design procedure and non-linear dead-beat controller development are given in detail. The main drawbacks of the AC/AC active-clamped HB converter are the high current stress and hard switching of the lower switches. In this paper, the all-switch zero-voltage-switching (ZVS) operation of the AC/AC active-clamped HB converter based inductive wireless charging system is explored. Moreover, the performance of the charging system under the variation of the mutual inductance and compensation capacitors are evaluated. Simulation and experimental results are given to verify the theoretical analysis.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
