Interleaved SPWM of Parallel CSC System with Low Common-mode Voltage
Bibliographic record
Abstract
Parallel current source converter (CSC) with multilevel modulation has the advantages to increase the system power range, reliability and improve output quality. In this paper, an interleaved sinusoidal pulse-width modulation (SPWM) for paralleled CSC system is proposed. The gating signals for each CSC are produced by comparing two triangular carriers and three-phase current references directly. Multilevel output can be achieved by simply interleaving the carriers. Comparing to the multilevel space vector modulation (SVM), the proposed method is more straightforward and easier to extend to N-CSC parallel system due to its inherent scalability and modularity. Moreover, lower common-mode voltage (CMV) and circulating current can also be achieved by the proposed SPWM strategy compared to multilevel SVM. The validity and effectiveness of the proposed method are verified on a paralleled CSC system with both simulation and 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.
