Abstract
In this paper, a low-power bidirectional DC/DC converter for inverter battery charger applications is considered. Initially, a galvanically isolated and synchronously rectified DC/DC converter topology is prototyped and its stationary performance evaluated. Next, a nonlinear dynamic model of the converter is derived using a state space averaging method. The dynamic model is nonlinear in the sense that it is a function of both converter duty cycle and load. The nonlinear model is then digitized and a proposed simulation algorithm derived and successfully validated against empirical data from the prototype converter. Finally, the large signal circuit dynamics are analyzed and an adaptive, fully digital pole placement controller is examined in adaptive and nonadaptive modes of operation.

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
