Asymmetric properties and ozone production of surface dielectric barrier discharge with different electrode configurations

摘要: For two electrode configurations of surface dielectric barrier discharge we investigated the asymmetry electrical parameters for positive and negative half-periods voltage ozone production. In both first was a square on one side plate. A set of 9 or 14 interconnected parallel strips other this plate served as second electrode. The is caused by different micro-discharges activity, which reflected peaks in current waveforms. When strip connected to high terminal power source series appears mainly during whereas only few smaller are observed half-periods. grounded situation reversed. configuration with 14 activity decreased comparison 9 Finally system produces, particular power, higher concentrations than with 14 concentration does not depend grounded.
