Novel Series <i>LC</i> Resonance-Pulse-Based ZCS Current-Fed Full-Bridge DC–DC Converter: Analysis, Design, and Experimental Results
Bibliographic record
Abstract
A current-fed full-bridge converter availing series resonance pulse to enable zero-current switching (ZCS) and voltage clamping of the semiconductor devices is proposed. Overlap in switching states of the devices enforces a short resonance pulse, due to series tank which naturally reduces the current to zero in the outgoing semiconductor devices. It causes zero-current commutation of the devices eliminating voltage spike across the semiconductor devices. Essentially, pulse-resonance offers reduced circulating current resulting in lower conduction losses and not demanding over-rated components. The proposed converter enables ZCS for wide variation in source voltage by implementing variable frequency fixed duty modulation eliminating the traditional requirement for additional clamping circuitry in conventional current-fed converters. Detailed experimental results on proof-of-concept hardware prototype rated at 500 W are demonstrated to verify the proposed claims and converter performance. With all other merits, proposed converter maintains high efficiency.

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.
