Parametric study of DBD Excilamps supplied with controlled square current pulses

Résumé

A parametric study of a system dedicated to non-coherent UV emission, by means of DBD excilamps, supplied by a controlled square shape current source is proposed. The presentation highlights on the one hand the performances experimentally obtained by combining together:  A set of 20 different bulbs with different diameters, gap and wall thicknesses (all the bulbs are filled with the same XeCl gas mixture, the length is 600mm and the injected electrical power can reach up to 500W) [1][3];  Different electrical power supplying conditions: magnitude, frequency (in the 30 kHz-200 kHz range) and duty cycle of the square shape current pulses [2] injected into the bulb. Low frequency burst modulation, with adjustable duty cycle of this supply is also superimposed. The performances concern the system power efficiency, the efficiency of the bulb conversion (electrical power to UV) and the adjustability of the power. On the second hand, we propose to present design considerations [4] of the power supply which has been especially developed for the purpose of these experiments. Finally, optimization developments, on the basis of the obtained experimental results are proposed.
