Parity-Time-Symmetric Wireless Power Transfer System Based on Self-Excited Converter
Bibliographic record
Abstract
The nonlinear parity-time-symmetric wireless power transfer (PT-WPT) system has garnered significant attention for its robustness against variations in the coupling coefficient. Currently, the implementation of nonlinear negative resistance primarily relies on switch-mode converters. Among these, the conventional PT-WPT system based on self-excited converters faces challenges such as limited output power and overall system efficiency (OSE). In this article, we propose a novel dual-supply self-excited PT-WPT system designed to address these challenges, offering a cost-effective solution. We present the circuit, coupled-mode model, and PT-symmetric condition of the proposed system. Furthermore, stability criteria of the system at each equilibrium point are analyzed using Lyapunov’s first method. Finally, we implement a single-supply system to validate the correctness of the models and stability criteria. In addition, a dual-supply system is constructed, achieving an output power of 101.2 W with OSE of 89.2%.

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.
