An Integrated Bidirectional Three-Phase AC Charger for Vehicle Applications with Buck-Boost Capability
Bibliographic record
Abstract
On-board integrated chargers for electric and plug-in hybrid electric vehicles are advantageous in that they have the potential to significantly reduce the external charging infrastructure requirements for charging a vehicle. This is made possible by re-using the power electronics and cooling systems already on-board the vehicle for charging. The disadvantages of on-board chargers, however, include added weight, volume and cost to the vehicle. In this paper, a novel on-board integrated three-phase ac charger topology is presented with buck-boost and vehicle-to-grid charging capability with minimum impact to the vehicle. Through use of a current source converter front-end, an input filter, a polarity inversion module and a differentially connected dual-inverter drive, a charger of three-port structure is realized with level-3 charging capability. This paper focuses on developing the operating principles of this novel topology. The operating principles are validated through PLECS simulations.

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.
