摘要
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 [16]. The derived model can be used for stability analysis purposes and is able to predict instabilities observed in different experimental setups.
