Recently, 35 W class Fluorescent lamps with 32 mm tube diameter are replaced with 32 W one with 26 mm in diameter to conserve lamp materials and to increase luminance efficiency. Moreover, 35, 28 and 14 W fluorescent lamps with 16 mm (T5) in diameter, which are nowadays developed, also may replace 32 W lamps again. Application of slim lamps, however, requires small sized electronic ballast to full...
In this paper, a Cold Cathode Fluorescent (CCFL ) model for high frequency dimming electric ballast simulation is presented. The model can be utilized for an electronic ballast simulation with continues dimming and transient mode simulation such as step dimming. The model is implemented using a PSPICE. The piezoelectric transformer is evaluated using an AC equivalent analysis. We are proposes an electronic...
