Study of effect of the nonlinear inductor behavior on the performance of resonant tank for driving fluorescent lamp

Applying Jiles-Atherton (JA) model to investigate the nonlinear inductance performance in the electronic ballast is a challenge but very attractive issue since it is possible to carry out continuous simulation with only several input parameters. In this paper J-A model has been successfully applied to model the dynamics of resonant inverter for driving a non-linear load: a fluorescent lamp. A semi-theoretical fluorescent lamp model developed from HID lamp model is adopted in this modeling. The whole system has been implemented in the Simulink of Matlab and the simulation results of voltage across the lamp and inductor and current through them are close to those measured ones reported in the literature papers.
