Comparing the Class E and Φ<sub>2</sub> Inverter Topologies for 13.56MHz Resonant Capacitive Power Transfer
Bibliographic record
Abstract
The class E and Φ<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> inverter topologies are compared in the context of a load-independent 13.56MHz resonant capacitive power transfer (RCPT) system intended for electric vehicle charging. In addition to efficiency and power capacity, radiofrequency emissions are evaluated based on the harmonic content of the voltages presented to the transmit resonator. Both inverters deliver over 1kW to the transmit resonator while maintaining system-level load independence. While the class E implementation is more efficient, the class Φ<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> inverter offers solid performance and a significantly reduced second harmonic, making it desirable from an electromagnetic compatibility standpoint.

How this classification was reachedexpand
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.
