High Precision Modeling of Saturable Transformers used as Voltage Regulators
Bibliographic record
Abstract
We bring in attention the almost missed magnetic device used as voltage regulator. It's about a partially saturable transformer, having four legs, two main and two controlling legs. The controlling legs work as a saturable magnetic shunt, while the main legs are never saturated. Thus, the secondary magnetic flux, respectively the secondary voltage can be rigorously controlled. The paper describes the principle of this application and uses the most modern tools that permit a rigorous study. The study is based on an accurate modeling and numerical simulation of the ferromagnetic core, respectively the primary/secondary/control circuit that permits a rigorous analysis in any working regime, including switching regime at any frequency. The modeling is made through an equivalent electric circuit described by the same differential-algebraic equation system as the studied device in transient regime. An example is given, that treats a 1 kVA low voltage regulator, using a SPICE simulation

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
