Space-vector PWM for inverters with split-wound coupled inductors
Bibliographic record
Abstract
This paper proposes a space-vector pulse width modulation (SVPWM) technique suitable for inverters with a coupled inductor output. The proposed approach is based on multi-level SVPWM and can offer superior performance when compared to other modulation techniques suitable for coupled inductor topologies. In particular the approach addresses issues related to common mode DC current balance in a three-limb inductor core and coupling between limbs in a three-limb core. The proposed approach provides a multi-level output voltage waveform while the total winding current distortion is significantly improved. This is achieved by appropriate choice of switching states such that effective low inductance modes are eliminated while generating half-wave symmetrical switching frequency voltage waveforms. The method presented is computationally simple and does not additional feedback signals when compared to conventional three-level SVPWM algorithms. The operation of the proposed drive structure is investigated by means of simulation results and verified by experimental 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.
