Shafi, MA and McMahon, RA (2012) Influence of voltage and frequency dimming on power losses in hf electronic ballasts for compact fluorescent lamps. IEEE Transactions on Industry Applications, 48. pp. 839-845. ISSN 0093-9994Full text not available from this repository.
Compact fluorescent lamps (CFLs) incorporating electronic ballasts are widely used in lighting. In many cases, the ability to dim the lamp is a requirement. Dimming can be achieved by varying the switching frequency of the inverter or by changing the voltage supplied to the inverter. The effect of dimming by both approaches on the power losses in the inverter is studied in this work. The lamp and associated inverter has been modeled in Pspice, using a behavioral model for the CFL. Predicted losses are in good agreement with experimental data obtained from calorimetry. After verification, the model was then used to determine the distribution of losses within the inverter, enabling a comparison of the effects of the two dimming methods to be made. © 2011 IEEE.
