Electrical modelling of homogeneous and filamentary dielectric barrier discharge at atmospheric pressure

Publication date: Available online 13 November 2019Source: Materials Today: ProceedingsAuthor(s): Abdelhamid Laiadi, Abdellah Chentouf, Youssef LaghmichAbstractAn electrical model of Dielectric Barrier Discharge (DBD) is proposed to model the homogeneous and filamentary discharge. In the first part, for the homogeneous discharge, an equivalent circuit based on the electrical behaviour of DBD is studied. The discharge current and the gap voltage signals are given as a result of model simulation. The analysis of charge transfer has been carried out by means of Lissajous figures, and the dynamic of the discharge is depicted by the discharge characteristic. In the second part, for the filamentary discharge, the randomness of streamers breakdowns and the high frequency of the current pulses have been modelled based on a statistical study of breakdowns distribution. The results of the simulation for the two modes of discharge will be compared to the experimental outcomes.
