A Misalignment Resilient System for Magnetically Coupled Resonant Wireless Power Transfer
Bibliographic record
Abstract
Misalignments between the transmitting and receiving coils of a wireless power system can significantly reduce power transfer efficiency (PTE). In this communication, we propose a novel magnetically coupled resonant wireless power transfer (MCR-WPT) system with good misalignment tolerance for wireless charging applications. Specifically, we employ three interconnected planar coils to form a transmitter that produce multiple paths of magnetic flux linkages and power to the receiver even in angular and lateral misalignment positions. Unlike other methods, no additional control circuits are needed so that the circuit can be easily realized and implemented. A prototype is simulated, fabricated, and tested. It has a wide angular misalignment range of 165° for the PTE of 20% or higher, which is 30% higher than 126° of the conventional system. It also has a wide lateral misalignment range of 180 mm for the PTE of 20% or higher, which is 73% higher than 104 mm of the conventional system. Thus, the proposed system presents a good and simple wireless power delivering system for practical applications in particular in the situations where angular and lateral misalignments occur in various degrees without prior acknowledge.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
