Abstract :
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 MATLAB and PSPICE The piezoelectric transformer is evaluated using an AC equivalent analysis. We are proposes an electronic ballast utilizing piezoelectric transformer for fluorescent lamps. The electronic ballast composed of piezoelectric transformers and Zero Voltage Switching(ZVS) inverter was implemented. It enables a fluorescent lamp to be turned on stably. Accordingly, simulation of a high frequency electronic ballast which operates a fluorescent lamp at high frequency is proposed. Simulation is carried out using MATLAB and PSPICE program to illustrate the performance to the circuit.
