A Novel Bidirectional Single-Phase Fifteen-Level Buck-Boost Rectifier for Power Factor Correction with Reduced Switch Count
Bibliographic record
Abstract
This paper introduces a novel bidirectional single-phase buck-boost rectifier for power factor correction that generates a fifteen-level voltage at its input. This multilevel rectifier as a high-power density topology with a reduced number of switches is based on the packed U-cell (PUC) converter. In this fifteen-level PUC-based rectifier (PUC15-rectifier), triple output terminals are available to supply various de loads at different voltages without requiring any dc-side passive filter. Besides, it is connected to the grid merely through a reduced size inductive filter. Generating a fifteen-level voltage waveform decreases the harmonic content of both voltage and current in the PUC15-rectifier input that makes it a reliable candidate for various industrial applications with a high-power quality performance. As PUC15-rectifier accurate operation depends on achieving four main control objectives and considering its dynamic model, a finite control-set model predictive control (FCS-MPC) method is also designed. The overall performance of the proposed PUC15-rectifier is verified by extensive simulation results.

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.
