Design of a Ferrite-Less Power Pad for Wireless Charging Systems of Electric Vehicles
Bibliographic record
Abstract
Inductive power transfer (IPT) systems unleashed a new era for wireless charging systems of electric vehicles (EVs). EVs can be charged stationary or in motion through IPT systems. Different types of power pads are introduced to increase the efficiency of IPT systems, among them, the most commonly used power pads is circular structure, another type with good potential is double D (DD) structure as recommended in Society of Automotive Engineers (SAE) recommended practice J2954. In this paper, a new power pad structure is proposed by combining circular and DD power pads to further improve the performance. Physical models of circular and DD power pads are first built by using specifications in SAE J2954, these models are then combined to form the proposed power pad. The design and simulation of the proposed power pad are carried out using the Finite Element Analysis (FEA) simulation software, ANSYS Maxwell 3D. Simulation results indicate that the proposed power pad shows improved performance compared to circular and DD power pads.

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.
