Three-Phase Current-Injection Rectifiers: Competitive Topologies for Power Factor Correction
Bibliographic record
Abstract
Three-phase current-injection rectifiers have been recently ranked among the most attractive AC-to-DC energy conversion topologies required in medium- and high-power applications. Their increasing popularity is mainly due to their structural and control simplicity and their high performance in terms of input power factor, current distortion, energy efficiency, and dc voltage regulation. They are actually considered solid competitors of six-switch rectifiers and the three-phase/switch/level (Vienna) topologies in applications where bidirectional power flow is not requested. The main benefit of the current-injection rectifier remains in the reduced number of high- frequency power semiconductors [two high- frequency insulated gate bipolar transistors (IGBTs) and three fast diodes, compared to six high-frequency IGBTs and six fast diodes for the six-switch rectifier, and three high-frequency IGBTs and 18 fast diodes for the three-phase/switch/level rectifier], making it more efficient and reliable.

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.
