A Novel Two-Phase Isolated Buck Converter with Increased Inductor Frequency and Low Diode-bridge stress
Bibliographic record
Abstract
This paper presents isolated DC-DC Buck converter to address issues in power converters for renewable energy applications. The proposed design features an isolated two-phase buck converter with coupled inductors and a phase-shift interleaving switching scheme. By reducing output current ripples, the system enables high-frequency operation while minimizing filter inductor size and improving the lifetime of energy storage elements (ESE). A significant advancement involves setting the switching frequency for the output inductor at four times the actual switching frequency. Operating the output inductor at four times the switching frequency reduces voltage stress and allows for a more compact inductor size. The proposed converter has no short-circuit issues, thus achieves a very high reliability. Moreover, the reverse recovery issues of the MOSFET body diodes are mitigated. Therefore, the proposed converter can be operated at a high switching frequency while maintaining a high efficiency. Detailed simulations and experimental results are provided to validate the performance of the proposed converter.

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.
