A boost-type high power factor single switch electronic ballast for compact fluorescent lamps (energy-saving lamps)
Bibliographic record
Abstract
A high power factor single switch electronic ballast is proposed in this paper for compact fluorescent lamp (CFL). With the gradual widespread use of CFL in the near feature to replace incandescent lamps, it is very important that CFL is able to maintain the same high power factor performance that incandescent lamps achieve. However, due to size and cost limitations, the current CFLs available on the market are not able to achieve high power factor. On the other hand, conventional high power factor electronic ballast using a boost pre-regulator is too costly for CFL applications. In this paper, the proposed electronic ballast solves the aforementioned problems by combining the boost power factor correction (PFC) stage and the resonant inverter stage using one switch. Moreover, the voltage stress and conduction loss across the switch is reduced when compared to other reference single switch topologies. Detailed description of the circuit operating principles will be discussed in this paper. Simulation and experimental results are given on a 11W CFL tube to highlight the merits of the proposed work.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
