Integrated active power filter auxiliary power modules for electrified vehicle applications with single-phase on-board chargers
Bibliographic record
Abstract
In single-phase on-board charger for the electrified vehicles, second-order harmonic currents and corresponding ripple voltages exist on the dc bus. The low-frequency harmonic current is normally filtered using a bulk film capacitor or additional active power filter (APF) circuit. This presents an obstacle for improving the power density as well as reducing the cost. This paper presents a new method for reducing the bulk capacitor in the single-phase charger. It applies the low voltage (LV) battery charger auxiliary power module (APM) as an APF to filter the low-frequency harmonic currents in the high voltage (HV) battery charger when the HV battery is charging. Hence, the integrated APM can achieve the APF function without extra power switches, heat sinks and corresponding gate drivers. Therefore, the proposed method can reduce the cost and volume for the dual-voltage charging system in the electrified vehicle applications. The effectiveness of the proposed method is verified by simulation results.

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.
