Effects of dielectric properties on electrical characteristics of dielectric barrier discharge generated by low frequency uni-polar high voltage pulses

Abstract

This paper presents experimental results concerning the effects of properties of glass and ceramic dielectric on electrical characteristics of the dielectric barrier discharge (DBD). The effect has been examined with a focus on low frequency uni-polar pulse driving in order to eliminate influences induced by the presence of residual charges and mestastable states in the discharge volume. The results revealed that at low frequency, in the glass reactor, the discharge just occurred after a delay with respect to moment when a high voltage pulse is applied to the reactor, whereas this phenomenon was not observed in the case of discharge in the ceramic reactor. Furthermore, in the glass reactor, DBD was generated with a much higher current peak and shorter discharge current duration in comparison with the electrical characteristics of DBD generated in a ceramic reactor. The differences are presumed to be the result of the difference in ability of trapping and binding surface electrons of dielectric layers.

Multiple current peaks and spatial characteristics of atmospheric helium dielectric barrier discharges with repetitive unipolar narrow pulse excitation

“…The discharge is accompanied by substantial current density and discharge intensity, achieving an efficient plasma system. To promote a large-scale industrial applications of pulsed dielectric barrier discharges (PDBDs), many groups have conducted researches on the characteristics of PDBDs [25,[28][29][30][31][32].…”
