Abstract
A novel N-level converter based on current-source power cells that is suitable for medium to high-voltage power applications is proposed. The topology is mainly the dual of the conventional topology based on voltage-source power cells. As such, it inherits all the advantages of the standard topology. But more importantly, the second current harmonic injected back by the normal operation of the single-phase current-source inverters are naturally cancelled out at the DC side of the power cells. This feature is assured by sharing the same magnetic circuit among the inverters connected to different load phases. As a result, the DC link filter required by the operation of the cell needs to be designed just to filter out the switching harmonics. Differently to voltage-source power cells based N-level converters, this ensures a small filter size, an important feature for medium to high power applications. Moreover, standard modulating techniques can be used such as SPWM, space vector, and Selective Harmonic Elimination without any penalties on the aforementioned advantages. Preliminary results confirm the theoretical considerations.

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
