Abstract
High-order filters, such as inductor-capacitor-inductor ( LCL) filter, have been popular in grid-tied power converters. Although featuring small size, LCL filters are not grid friendly due to inherent resonance, especially when a large number of converters are in parallel operation in todays electric grid to attain modularity, reliability, and redundancy advantages. Thus, this article reconsiders the low-order L filter in parallel converters to eliminate the resonance and in turn to simplify the control. It is found that by interleaving a certain number of converters, the L filter will be sufficient to meet the harmonic limit requirements of the standards, while the filter size can be even smaller than the LCL filter. This further contributes to cost reduction as a promising solution for grid-friendly converters.

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
