Abstract

fetched live from OpenAlex

The paper presents a novel single smart filter and energy miser for single phase motorized and inrush type cyclical loads such as air-conditioning blowers, refrigerator and water-pumping applications. The smart filter is a tuned-arm single-phase filter equipped with a pulse width modulation (PWM) triggering circuit and a novel dynamic RMS current tracking controller. The smart filter/energy miser ensures supply power quality enhancement, less source current/load voltage waveform modulation as well as enhanced electric energy efficiency for cyclical, inrush type nonlinear motorized loads. The PWM switching scheme establishes a dynamic on-line varying duty cycle ratio /spl alpha/ that modulates the apparent smart filter impedance to provide an effective compensating filter current level to cope with load current waveform distortion.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
