Abstract
Shunt type static VAr compensators are an effective means of increasing the transmission capability of power systems and of increasing the power factor of industrial loads. This paper presents an alternative in the form of a series-connected transformer coupled PWM inverter. The scheme consists of a current source inverter connected to a self controlled DC bus. It presents the following features: (a) instantaneous series injected voltage control through online modulation index control; and (b) steady state modulation index control to a value near unity. The first feature results in fast dynamic response, while the second feature ensures that the harmonic distortion of the injected voltage under steady state operation is kept to a minimum, independently of the operating conditions. Operation of the compensator and of the two loop control scheme are presented. Simulation and experimental results on a prototype unit confirm the feasibility of the proposed structure.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

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
