Abstract
This paper presents a standby power supply/active power filter (SPS/APF) system. This system provides combined functions of high efficiency power backup and harmful harmonics elimination. Based on the bilateral power converter using a current forced switching scheme, the line current can be sinusoidally regulated with unity power factor in APF mode and the voltage waveform distortion can be kept small in SPS mode by instantaneous voltage control. Introduction of the harmonic problems generated by the nonlinear loads, the calculation method of the instantaneous reactive current components achieving current distortion compensation and power factor correction, and the full digital control hardware and software schemes using a TMS320C25 digital signal processor are discussed in detail. Finally, the theoretical analysis is verified both by simulated and experimental results in a 3 kW laboratory prototype system.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

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
