Abstract
A three-phase Hybrid Current Source Converter (HCSC) that employs 3 SCRs and 4 switches (IGBTs) was proposed as an economical alternative to the conventional 6-switches Current Source Converter (CSC). It presents bi-directional power flow capability, does not generate low order harmonics and can operate with variable power factor. However, the force-commutated switches need to operate with increased switching frequency and remain on for minimum periods of time for safe commutation of the SCRs what leads to a reduced maximum modulation index (m <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">amax</sub> ). This paper describes a space vector modulation (SVM) technique that allows one natural (soft-switching) commutation of SCRs and IGBTs per SVM cycle. Besides, the reduced stress on the semiconductors, this allows the use of SVM sequences with three segments and an increase on the maximum modulation index (m <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">amax</sub> ) of the 3-SCR and 4-IGBT HCSC.

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
