A new non-multi-level structured, H-bridgeless DC/DC bidirectional converter with low voltage stress and complete soft-switching operation
Bibliographic record
Abstract
A new soft-switched, 5-switch string-structured bidirectional DC/DC converter with an isolated CLLC resonant circuit is presented in this paper for energy storage applications. In the proposed circuit, only one switch and two diodes are added to the conventional 4-switch string structured converter enabling the converter to operate in rectifying mode with lower output voltage ripples and higher efficiency. A CLLC resonant circuit is designed to allow stepping-up or stepping-down the voltage to desired value with the same operating frequency in both boost and buck modes with variable frequency control. All the switches and diodes are able to achieve soft-switching to enhance the circuit efficiency. Simulation results are given on a 1kW, 100VDC/300VDC system to highlight the merits of the proposed converter. Preliminary experimental results are also provided on a laboratory scale 100/300VDC prototype to further support the features of this work.

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.
