Flux Minimization in Interphase Coupled Inductors of Parallel-Connected Voltage Source Converters
Bibliographic record
Abstract
A flux compensation technique is described to significantly lower the peak flux in interphase inductors used to suppress the flow of high-frequency circulating currents between interleaved voltage source converters (VSCs) operating with the discontinuous pulse width modulation scheme (DPWM). The technique described is useful to reduce the required cross-sectional area of interphase inductors, which reduces the size, weight, and material cost of the magnetics in interleaved VSCs. Coupled inductors (CIs) with cross-coupled windings are used to demonstrate the performance of the flux compensation technique using simulation and experimental results of an 11 kW (300V <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">dc</inf> , 208V <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">ac</inf> /31A) laboratory prototype. The inductor cross-coupled winding arrangement lowers the effective series inductance of the interphase inductors and makes it possible to produce high-frequency fundamental PWM output voltages with a very low voltage drop across the inductors.

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.
