A Topology-Reconstructed Minimum-Current-Stress Modulation for a Single-Phase Isolated DC–AC Converter
Bibliographic record
Abstract
Isolated dc–ac converters, driven by their high-power density and efficiency, have become a compelling alternative for line-frequency transformer-based dc–ac converters in applications requiring isolation and bidirectional power flow. In this article, a single-phase isolated dc–ac converter is studied, and a modified topology-reconstructed minimum-current-stress (MCS) modulation is proposed for achieving high efficiency and superior power quality. This method discusses the topology reconstruction of the dc–ac converter and treats it as two dual-active-bridge (DAB) dc–dc converters, allowing the dc–ac converter to inherit the efficiency optimized methods of the DAB converter. Then, by combining the MCS modulation of the high-efficiency DAB converter, the modified topology-reconstructed MCS modulation is proposed for the single-phase isolated dc–ac converter. In addition, superior power quality can also be achieved by using the proposed method. Finally, a small-scale experimental platform is constructed to verify the effectiveness of the proposed topology-reconstructed modulation scheme for the single-phase isolated dc–ac 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
