An Open-Circuit Fault-Tolerant Scheme for Single-Phase Current-Fed Dual-Active-Bridge DC/DC Converter
Bibliographic record
Abstract
Power interruptions are intolerable in many industrial applications, so high reliability becomes exceedingly pivotal to power converters. Fault-tolerant schemes attract more attention as an effective approach to improve reliability. However, due to the low-device-redundancy and asymmetrical structure, fault-tolerant schemes have not yet been reported on the single-phase current-fed dual-active-bridge (CF-DAB) converters. To address this challenging issue, an open-circuit fault-tolerant scheme is proposed in this article. With the proposed fault-tolerant scheme, the single-phase CF-DAB converter can maintain power delivery even if facing the open-circuit faults of two specific switches and the middle capacitor. Meanwhile, potential voltage spikes can also be suppressed effectively without the snubber function of the middle capacitor, which protects the switching devices from high-voltage stresses. Subsequently, the modulation scheme, mode characters, and control structure are elaborated. 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.
