Concept study and feasibility analysis of current-fed power electronics for wireless power transfer system
Bibliographic record
Abstract
This paper studies and explores feasibility of wireless inductive power transfer (IPT) systems using current source inverter (CSI) topology for electric vehicle battery charging applications. Possible IPT systems with CSI topology includes current-fed push-pull, half-bridge and full-bridge converters. Also the possible compensation or resonant tank network at transmitter side is parallel LC or CCL type. Receiver side tank network is generally selected as series LC type to keep least number of components onboard. First, a brief overview of all possible IPT power supplies suitable for medium power applications is presented. This IPT topologies include series, parallel and several combinations of series-parallel compensation networks. Then a detailed study and comparison is presented for several current-fed IPT systems. Based on the study both the current-fed full-bridge and half-bridge topologies with CCL tank network provides performances suitable for higher power applications. A 1.2kW hardware prototype is developed and experimental results are presented to verify the comparative study results.

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.
