Space Vector Modulation with Flexible Three-Segment Switching Sequence for Five-Level Inverters
Bibliographic record
Abstract
This paper presents a space vector modulation (SVM) algorithm with flexible 3-segment switching sequence and its application to five-level inverters. In the flexible 3-segment SVM, the leading state of the switching sequence is selected according to minimum change of state value to ensure minimum switchings when the space vector hops between different triangles in the vector plane, and the switching sequence is generated in a flexible way according to the state value of the leading state, rather than using predefined patterns as most conventional SVM schemes do. The algorithm is simplified and the waveform symmetry is guaranteed by a simple `state rotation and inversion' to reproduce the switching sequence of Sector I for the other sectors. Simulation results show that the flexible 3-segment scheme can minimize or eliminate extra switchings. For a given switching frequency, the proposed 3-segment scheme yields lower WTHD than the conventional 7-segment scheme. Experimental spectrum of the output voltage verifies the 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.
