Abstract
High efficiency totem pole power factor correction (PFC) converters have attracted a significant attention in recent years. State of the art wide band gap (WBG) devices make continuous conduction mode (CCM) totem pole PFC feasible for medium to high power applications. However, higher costs and complex control are the main barriers to widespread industrial adoption of this topology. Control challenges including current spikes during zero crossings, DC component in AC mains current and AC voltage drop handling are investigated in this paper. Appropriate control measures are utilized to address these challenges. Additionally an accurate low cost DC current reduction method is proposed. The effectiveness of the proposed control is verified through real-time hardware-in-the-loop simulation of a 1450 W interleaved totem pole PFC converter.

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 it
