Abstract
This paper proposes a new design of compensation capacitors for two resonant Inductive power transfer (IPT) topologies to obtain load independent zero-phase-angle (ZPA) operation at inverter output. Parallel tank network is used in the primary side to achieve high quality IPT coil current, lower inverter switch current stress and zero-voltage-switching (ZVS) of inverter devices. Conventional design techniques of these IPT topologies ensures ZPA operation for a specific load impedance only i.e. the ZPA operation is load dependent. Therefore, either the operating inverter switching frequency or the compensation capacitors are required to be modified dynamically to reach new ZPA point. In this proposed design both the primary and secondary tank capacitors are designed such that this ZPA point is always maintained irrespective of load variation. This design is based on passive selection of circuit parameters, thereby making is suitable for practical use. Detail mathematical analysis is reported and experimental results obtained from a 1 kW lab-prototype are demonstrated to verify the analysis and performance.

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 it
