An integrated EMI suppression Y-caps applicable to high frequency planar transformers in high power DC-DC converters used for electric vehicle
Bibliographic record
Abstract
Planar magnetics are very suitable for automotive applications due to the low profile structure. DC/DC converters in electric vehicles (EVs) use planar magnetics to minimize their size and weight and to increase their ability to withstand mechanical vibrations. Typical planar transformers (PT) in DC/DC converters used in EVs have high inter-turn and interlayer capacitances, which have detrimental effects such as high peak currents, increase voltage overshoot across secondary rectifying devices, and increase leakage current. The paper proposes two winding structures to mitigate the effects of inevitable stray capacitances of planar transformers. In addition, the second strategy integrates the Y-capacitors into the transformer in order to suppress Common-mode (CM) EMI noise generated in the DC-DC converter. The effectiveness of the proposed winding strategy is validated by analytical and experimental results that are presented in the paper.

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.
