Structure pattern peculiarities and electrical characteristics of surface dielectric barrier discharge in air driven by impulse and sine high voltage

摘要

Structure patterns and electric characteristics of surface dielectric barrier discharges in air driven by periodic unipolar impulse voltage with ns front duration and sine voltage of the same frequency f = 15 kHz are presented. An influence of voltage impulse polarity, amplitude and impulse duration on discharge characteristics is shown to exist. The currents extracted from the surface discharge plasma layer by d.c. voltage of additional third electrode are found to depend on the waveform of the applied high voltage impulses.
