Abstract
Renewable energy sources are quickly becoming incorporated into increasingly distributed electrical utility grids. An ever present issue when interfacing these sources is that of harmonic distortion reduction at the inter-tie point. Presented in this paper is the modeling and analysis of a rarely employed technique for harmonic reduction using synchronized phase shifted parallel PWM inverters with current-sharing reactors [1-4]. A main contribution of this paper is the introduction of parallel inverters equivalent circuit model that permits any number of inverters operated in parallel to be analyzed with accuracy, simplicity and ease. The validity of the results obtained using this equivalent is investigated analytically and simulated using MATLAB/Simulink and PSpice for one, two and three parallel phase-shifted inverters using double-edge asymmetrical RSPWM modulation with various modulation indices and carrier to reference frequency ratios.

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
