Abstract
This article presents a new online diagnostic technique for multiple power switch faults in switched reluctance motor (SRM) drives. Unlike the existing schemes, nearly all potential failure scenarios in the power switches of the standard asymmetric half-bridge (AHB) converter are considered in this work. First, a new current sensing scheme is proposed without modifying the standard AHB structure and the obtained current errors for current control of the drive system are analyzed for fault diagnosis. Second, a new fault variable is extracted from the dc-bus current, and subtests are introduced to detect and locate the failure of multiple switches in a phase-leg with the same or hybrid faults. Diagnosis of multiswitch faults in the same or different phases is achieved within a few sampling periods. The diagnostic capability of the proposed methods is thoroughly validated through experimental studies using a three-phase 12/8-pole SRM drive system.

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 it
