Abstract
The commercial power supply for the gate driver of integrated Gate Commutated Thyristors (GCT) is an expensive device since the supply's output must withstand the high voltage potential of the GCT switch against all other relevant potentials in the converter. This voltage potential varies from a few thousand volts to several ten thousands of volts over the GCT application range. In this paper, a novel self-powered supply (SPS) is proposed for the GCT gate driver, where the supply obtains energy from the snubber circuit of the GCT switch and then provides a regulated dc voltage for the gate driver. Since the snubber circuit is at the same potential as the GCT, the insulation level of the supply is reduced from thousands of volts to a couple of hundred volts, leading to a significant reduction in cost and size. The supply configuration is introduced and its operating principle is discussed. The design guidelines and experimental results are also provided.

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
