Coordinated Power Sharing for Enhanced Utilization of Mixed Energy Storage Media in Dual-Inverter Electric Vehicles
Bibliographic record
Abstract
The dual inverter topology driving an open-winding motor is well-known in high voltage motor drive applications. This structure allows two energy sources to be directly connected to an open-winding motor, which enables the integration of supercapacitors into a battery electric vehicle without the need for additional dc/dc power electronics or associated magnetic components. Unlike existing solutions, this paper introduces an innovative power management scheme that offers optimal usage of the supercapacitor to provide mixed active and reactive power assist under fluctuating vehicle dynamics. Power regulation is achieved by controlling the direct and quadrature axis voltages of twin inverters. In addition to classical peak power assist, the proposed controller extends the functional capability of the dual inverter drive by re-purposing a depleted supercapacitor to supply reactive armature voltage for speed range extension. A 10kW laboratory prototype is presented to verify the proposed power management controller.

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.
