Fluorescent lamp model employing tangent approximation

A circuit model simulating the electrical characteristics of a fluorescent lamp operating at high frequency is proposed. The model is based on exponential approximation that represents the lamp equivalent resistance variation as a function of power, constructed by experimental results for several power levels. Simulation results and experimental data are presented to verify the feasibility of the model and, moreover, an electronic ballast example using the proposed model is presented to further demonstrate its applications.
