  1. Characteristics & Issues for Compact Fluorescent Lamps(AS/NZS EL041 Meeting) Neville R. Watson, University of Canterbury 12 March 2008

  2. Outline • Background • Types of CFLs • Direct Harmonic Penetration Study • Detailed Transient Simulations • Other Studies • Standards • Conclusions

  3. Missing Components Fuse on Input Filter Capacitors missing

  4. Same brand September 2007 Does have PTC No Fuse No place for Filter Capacitors

  5. PTC missing

  6. 3rd Pro. Project 2008

  7. Power-factor

  8. Types of CFL Ballasts

  9. Types of CFL • No Power-Factor Control • Passive Power-Factor Control • Valley-Filling (or equivalent) • Active Power-Factor Control

  10. Eclipse 20W CFL

  11. OSRAM DuluxStar 20W (2007)

  12. E-Lite CFL (July 2007)

  13. Eco-Bulb (2007)

  14. What is possible for a CFL CFL for North American Market

  15. What is possible for a CFL

  16. Basic, no filtering Active Power-Factor Control Basic, with filtering Valley-fill or Equivalent

  17. Basic, no filtering Active Power-Factor Control Basic, with filtering Valley-fill or Equivalent

  18. Notice: form bands based on circuit type

  19. Analysis Methods

  20. Frequency Domain Analysis Direct Harmonic Penetration Study

  21. CFL Characteristics

  22. CFL Characteristics

  23. Test System 28,800 (15 4 1086) customers modelled

  24. Breakdown of Losses into Branches

  25. Breakdown of Harmonic Losses into Frequencies

  26. This is like comparing apples and oranges
