A Thyristor-Based Solid-State DC Circuit Breaker With a Three-Winding Coupled Inductor
Bibliographic record
Abstract
Thyristor-based solid-state circuit breakers (TCBs) have become a popular protection solution for DC microgrids, due to their low construction cost, high efficiency, and fast response time. Despite numerous TCBs being proposed, the majority of them still suffer from low controllability, low current interrupting reliability, slow fault isolation, poor reclosing protection, and high conduction loss. Inspired by these issues, a novel TCB with a three-winding coupled inductor is proposed in this paper. First, it could interrupt both operating and fault currents actively and reliably with its bidirectional symmetric construction, ensuring high controllability and reliability. Second, during the current interrupting process, the arrester immediately works after the proposed TCB acts, which makes the fault currents at both source and load sides drop, thus effectively suppressing the fault currents. Third, the capacitor and thyristors in the triggering circuits can automatically restore to their initial states after interrupting the current, thus ensuring a reclosing protection function with no extra operation sequences. Fourth, since the conducting branch only contains one set of parallel thyristors and an inductor coil, the conduction loss of the proposed TCB is low, thus ensuring effectiveness. The working principles, design guidelines, and experimental results are presented. The advantages of the proposed TCB are further demonstrated through comparison with some existing schemes.

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.
