Dimmable electronic ballast for HPS lamp operating in LF

In this paper we present the study, design and realization of a low frequency dimmable electronic ballast controlled by a microcontroller of a dimmable electronic ballast on micro controller. Indeed, it is with short current drop (which can be variable). We are interested in controlling the spectral radiation response in the of the spectrum , especially d-lines. A comparison between simulations and measurements of HPS lamps confirms the agreement between the model and the experiment.
