Abstract
The paper presents a new transformerless single-phase single-stage buck-boost grid-connected voltage source inverter (VSI) topology. The topology can achieve efficient power conversion with a wide input voltage range, number of magnetic devices reduction and low leakage current. The proposed VSI topology consists of high frequency semiconductors for shaping inductor currents, and low frequency semiconductors to form grid CL filter structure for different conditions. This CL filter uses the same buck-boost inductor, thus no additional line frequency inductor is required. Besides, common mode voltage, a main problem of transformerless grid-connected VSI, is mitigated, since the capacitor in the CL filter clamps the voltage between the grid and the bus terminal. The performance of the proposed VSI is experimentally verified. The results show that the proposed VSI guarantees sinusoidal output current and wide input voltage range, and has a good agreement with the theoretical findings.

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
