Abstract :
A small-signal linear model of a cold cathode fluorescent lamp (CCFL) ballast that employs a voltage-driven piezoelectric transformer is presented. The model takes into account the lamp dynamic and is based on the application of the generalized averaging method presented in . The derived model can be used for stability analysis purposes and is able to predict instabilities observed in different experimental setups
