Abstract
Renewable energy generation systems are inherently affected by fluctuating environmental conditions, resulting in wide variations in output voltage that challenge conventional power-conversion methods. This paper presents a novel single-stage, non-isolated inverter architecture that combines a switching-cell buck-boost topology with a commonground design. The proposed configuration enables seamless stepup/down voltage regulation and DC-AC inversion within a single power stage, eliminating shoot-through risks without requiring dead-time PWM. The switching cell structure allows for the independent control of each leg, simplifying modulation and improving the dynamic response. Meanwhile, the common-ground connection between the photovoltaic source and grid neutral clamps the high-frequency common-mode voltage, effectively mitigating leakage currents in transformerless systems. To verify its performance, detailed simulations and hardware experiments were conducted.

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
