Performance analysis in terms of line current harmonic injection and DC bus output voltage regulation of two three phase boost rectifiers operating under unbalanced load
Bibliographic record
Abstract
In this paper, the authors present a comparative study between two three-phase boost rectifier topologies. The topologies considered are three-level (18 switches) and two-level (6 switches) converters. The neutral point of the three-phase source is connected to the midpoint of the DC bus to provide a zero sequence current path. The comparison is carried out for both balanced and unbalanced load connected to the centre tap of the DC bus. The control of unbalanced voltage with the injection of the zero sequence current is achieved using the PWM technique. The THD of line-currents, efficiency and power factor are compared for a 25 kW system operating at 3 kHz. Simulation results obtained by the power system blockset (PSB) tool for both steady state and dynamical operations are presented and analysed.

How this classification was reachedexpand
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.
