Modified resonant converters for contactless capacitive power transfer systems used in EV charging applications
Bibliographic record
Abstract
In the past decade wireless power transfer with the help of magnetic field has been most popular. Contactless capacitive power transfer (CPT) system is an alternate form of wireless power transfer that is currently gaining popularly. However, capacitive power transfer systems are predominantly utilized in low power and small air gap applications applications due to low efficiency and high voltage that are developed across the coupling interface. This paper proposes two modified converters that utilize capacitive coupling for wireless electric vehicle charging applications. The proposed topologies over come the limitations of the existing wireless capacitive systems making them usable for high power applications. The paper discuss CPT systems for small and large airgap EV charging employment. The working, design and analysis of the two converters are detailed in this paper. The characteristics of the two converters that make the proposed topologies for EV charging applications are discussed. Finally, a 1kW CPT system is designed for the proposed converters and the simulations obtained agree well with the theoretical values that are calculated.

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.
