Design Procedure for High-Frequency Operation of the Modified Series-Resonant APWM Converter to Reduce Size and Circulating Current
Bibliographic record
Abstract
In this paper, a generalized analysis for the auxiliary network in a modified series-resonant asymmetrical pulse-width-modulated (APWM) converter is performed to produce a design procedure that ensures that zero voltage switching (ZVS) is achieved for any series-resonant APWM converter design. New equations that correctly predict the magnitude of auxiliary current are obtained by accounting for the trapezoidal nature of the waveforms associated with high-frequency operation, and the dead time between the switches in the half-bridge. A design example of a 48-V/1.2-V, 25-A converter operating at 1 MHz is chosen to highlight the validity of the proposed design and that superior results can be achieved if the resonant tank is designed in tandem with the auxiliary network. Experimental results verify that ZVS is achieved, and that the proposed design reduces the auxiliary inductor by close to a factor of 3.

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.
