Programmable current converter synthesis for the evaluation of UV radiation of excimer lamps

This work proposes the development of a power supply for Dielectric Barrier Discharge (DBD) lamps, intended for the evaluation of a water treatment system based on UV radiation. The DBD excimer lamp is an attractive source of UV because of its cost and radiation power. The proposed converter is conceived to control the UV radiation by programming different lamp current intensities, duty cycles and frequencies. For the converter synthesis, a capacitive electric equivalent model of the DBD is used. A simulation of the converter and its control analysis is presented.
