A Single Stage 1.65kW AC-DC LLC Converter with Power Factor Correction (PFC) for On-Board Charger (OBC) Application
Bibliographic record
Abstract
A single stage 1.65kW AC-DC LLC converter with Power Factor Correction (PFC) for OBC application is proposed. A boost inductor is not required since the LLC converter serves as both the AC-DC and DC-DC stage which provides all the functions of rectification, PFC, output voltage regulation and galvanic isolation. A design methodology is proposed in this paper to maintain the output voltage regulation and PFC over the entire AC input voltage range from zero to peak voltage. Benefiting from the true-single-stage structure, the quantity of active switches and magnetic components is reduced. Therefore, high power density and high efficiency can be achieved with an overall reduction in the number of components. An experimental prototype is designed based on the LLC PFC design methodology. Stable DC output voltage regulation is implemented with over 99% Power Factor. Experimental testing is conducted which achieves over 2.9kW/L power density and 96.9% overall efficiency.

How this classification was reachedexpand
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.
