Abstract
A dual-modular-multilevel-converter (MMC) structure is presented that allows multifrequency power transfer between its ports. By exploiting a three-winding transformer, where the converter-side windings can multitask by accommodating currents with multiple frequency components, the proposed MMC structure can be deployed for two different applications: 1) a dc–ac MMC with independent control of currents in the two dc poles to accommodate unbalanced conditions in bipolar dc systems, and 2) a three-port MMC that can achieve simultaneous dc–dc and dc–ac conversions between an ac grid and two dc systems. DC flux cancellation is imposed in the transformer core by using a center-tapped connection of the converter-side windings. A unified control scheme is developed that independently controls dc and ac terminal power transfers while keeping submodule capacitor voltages balanced. Converter operation and dynamic controls are validated by simulation and experiment.

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
