Abstract
This paper proposes a new medium-voltage high-power converter topology to produce multilevel output voltages. The proposed converter is based on conventional modular multilevel converter (MMC). The recommended topology improves the conventional MMC by introducing a middle arm to the standard MMC topology which comprises of only the upper arm and the lower arm. The proposed MMC topology can generate the same number of output voltage levels as conventional MMC with a less submodule (SM) count, requires half the dc-link voltage, and uses only one dc-source and one buffer inductor. This paper first illustrates the new topology and explains its operation modes, then it provides simulation results to verify the theoretical outcomes. A prototype has been built to investigate the performance of proposed MMC.

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
