Experimental investigation of frequency effect on the ignition and damping of barrier discharge in various gasses medium

The applications of Dielectric Barrier Discharges (DBD), which play a significant role in energy efficiency and lighting technology, are increasing day by day. Determination of ignition and damping voltage values of DBD at various frequencies and different gas environments is of great importance in terms of lighting technology and various industrial applications. Therefore, in this thesis, an experimental study has been carried out to determine some parameters of DBD ignition and damping voltages in various frequencies and different gas environments. In the study, the supply voltage was gradually applied at certain frequencies to the cylindrical plane electrode system, which was placed in a specially designed vacuumable reactor, and these experiments were repeatedly carried out in various gas mediums and then the voltage and current parameters of the system were measured. Using these measurements, the voltage-current graphs of the system were created for each medium condition separately. As a result of the study, the frequency and gas species have a significant influence on the ignition and damping voltages of the discharge, and the increase in frequency greatly facilitates the ignition of the DBD; similarly, the conductance of the ambient gas resulted in a significant reduction in the ignition voltage level of the DBD.
