Coil design approach for indirect-fed resonant wireless power transfer system
Bibliographic record
Abstract
A novel coil design approach for an indirect-fed resonant wireless power transfer (RWPT) system is proposed in this paper. The design goal is to find the minimum size of the coils for the RWPT to deliver a minimum desired power in all positions in a given distance range. Neumann formula is applied to the extensions of circuit models to obtain dimension-bound equations for output power. The design bottleneck is shown to be the power delivered at the farthest distance in the range dictating the size of the coils. It is also observed that designs with unequal coil sizes cannot provide an optimal power delivery. Using the flowchart introduced in this paper, the minimal size of coils which satisfies the minimum output power are determined. Moreover, effects of changing the optimal size on mutual inductance and knee point relocation are investigated. The simulations are given for a 15W load for a range of 40-80 cm.

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.
