Abstract :
A small-signal linear model of a CCFL ballast that uses a voltage-driven piezoelectric transformer is presented. The model includes the lamp dynamic and is based on the application of the generalized averaging method presented in (R. Sanders, et al., 1991). The derived model can be used for stability analysis purposes and is able to predict instabilities observed in different experimental setups
