Magnetically Coupled Interleaved Buck Integrated On-Board Charger for Light Electric Vehicles
Bibliographic record
Abstract
This paper presents a novel onboard charger that integrates the electric vehicle’s motor into its charging system. One of the novelties of this invention is the use of a permanent magnet synchronous motor (PMSM) as a coupled inductor in place of a conventional inductor. Additionally, the inverter used to drive the vehicle’s motor is used in conjunction with the PMSM to establish an interleaved buck converter configuration for battery charging. This is made possible because the special built-in features of the PMSM allow the motor to remain still without any torque generation and decrease the current ripples in the charging mode of operation. The minimal current ripple content and the zero-torque generation have been proven mathematically, and the different charging operational modes of the model have been studied. The proposed charger’s efficiency has also been analyzed, tested and evaluated experimentally on a 960W charger to confirm the robustness of this novel system in this paper. The research findings prove that the system performs very well, with an efficiency of 94%, providing a reliable charging solution for light electric vehicles.

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.
