Dynamic modeling of an ultraviolet (UV) fluorescent lamp has been addressed in this paper. Based on a recently developed lamp model, a semiempirical modeling technique has been applied for dynamic modeling of a UV fluorescent lamp. In the modeling stage, simple electrical measurements have been used. In the proposed mathematical model, model parameters have been determined from electrical voltage and current measurements of the lamp under ac operation at operating frequency. In order to calculate the model constants, the lamp data from lamp manufacturers have not been required. Once the model constants have been determined at 50-Hz main fundamental operating frequency, with the same set of parameters, the model can predict the lamp terminal characteristics accurately under different operating conditions. Different operating frequencies, such as low-, medium-, and high-frequency operations, have been considered, and good simulation results have been achieved when the lamp power has been reduced to different operating levels. The simulation results are confirmed by laboratory experiments.
