A Capacitor Fault-Tolerant Scheme for Dual-Active-Bridge DC/DC Converter
Bibliographic record
Abstract
Recently, the dual-active-bridge (DAB) DC/DC converters are widely utilized in renewable energy systems. Lots of research on the optimization of DAB converters has been conducted, including novel topologies, modulation schemes, control schemes, and fault-tolerant schemes for active switches or riding-through, etc. However, there is a limited fault-tolerant scheme developed for capacitor failure in DAB converters so far, due to the low-device redundancy. To address this important issue, a capacitor fault-tolerant scheme is proposed in this paper. With the proposed scheme, the DAB converter can maintain power transfer sustainability even if the port capacitors break down. Besides, potential voltage spikes can also be suppressed by the proposed scheme when the snubber function of port capacitors is lost. Subsequently, the modulation scheme, topology characters, and control scheme are elaborated in this paper. Finally, the experimental results based on a scale-down laboratory prototype are presented to verify the feasibility of the proposed fault-tolerant scheme.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
