Abstract
This paper proposes the implementation of a receiver-side voltage doubler into a WPT (wireless power transfer) charging system to reduce the transmitter currents at the cost of increased receiver current for a fixed power transfer level. For a WPT system with a multi-coil transmitter and simple receiver, this results in an efficiency improvement due to the overall reduction in copper losses. A WPT system with a three-coil transmitter and single coil receiver is investigated, and up to a 13% system coil efficiency improvement was obtained from simulations for 3.3 kW output power with a receiver-side voltage doubler compared to if a standard full-bridge rectifier was used. Experimental results were then obtained for a reduced scale 1 kW WPT system using a voltage doubler, validating the performance of the applied models.

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
