Abstract

fetched live from OpenAlex

Asymmetrical operation is a main challenge for the application of bipolar dc distribution systems. As a promising solution, paralleled dual converters balance the dc pole voltages without the penalties of increased power ratings by integrating a center-tapped transformer. The interleaving operation of dual converters could realize the harmonics cancellation of neutral line current, which is elaborated by harmonics distribution analysis presented in this paper. Moreover, phase shifting strategy is used to offer an additional degree-of-freedom (DoF), the resultant 2DoF modulation strategy is able to significantly suppress the common-mode (CM) current, which could reduce the size of CM choke and improve power density of converter. The validity and benefit of 2DoF strategy for dual converters are verified by both simulation and experimental results.

Not 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.
