Abstract
To date, all of the existing and planned converter-based FACTS controllers are realized based on the voltage-source converter topology. With the evolution of high-performance semiconductor switches and super-conducting materials for inductors, and also with the development of new modeling and control techniques, current-source converter topology is gaining ground in competition with the voltage-source converter topology in high-power applications, including FACTS controllers. In this paper, the voltage- and current-source converter topologies are compared from different viewpoints of device rating, DC-side energy storage requirement, AC-side waveform quality, start-up, and cost. The comparative evaluation of the two topologies is performed based on analysis, as well as experimental results.

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
