Modeling and Electrical Characterization of Atmospheric-Pressure Surface Dielectric Barrier Discharge (SDBD) in Argon

We are interested in this work by glow surface discharges created in dielectric barrier SDBD. Our SDBD use pulse and rectangular high voltage waveforms to generate atmospheric argon plasma. COMSOL® and Pspice® software are used to perform electrical modeling of the SDBD discharge. The model is about a plane–parallel configuration with a double isolating wall. COMSOL® software is used to simulate and investigate the movement of charged species and the electrical characteristics of the discharge where a high pulsed voltage is supplied to the electrodes. However, Pspice® software is used to explore the electrical characteristics of the proposed equivalent electric circuit of the SDBD considered geometry. A comparison of simulation results obtained by the two softwares is done. It concerns the electrical characteristics of the SDBD created under different waveforms of the applied voltage.
