A high-voltage nanosecond pulse generator based on a barrier discharge

The paper presents the results of studying the interaction of microdischarges in the cell of dielectric barrier discharge (DBD) with enamel-based surface films deposited on a fabric-based laminate. TiO2 powder was added to the surface films. Elemental composition of the surface films was studied in the areas with different level of microdischarges exposure. Before measurement, the samples were bonded onto a 25 mm aluminum specimen with conductive silver paint. The metal was coated with a thin film (13 nm) of carbon using magnetron sputtering method. The observations were carried out using Hitachi SU8000 field-emission scanning electron microscope (FE-SEM). Images were acquired in secondary electron mode at 30 kV accelerating voltage and at working distance 8-15 mm. EDX-SEM investigation and mapping were carried out using Oxford Instruments X-max EDX system. Before measurement, the samples were coated with a thin film (13 nm) of carbon using Cressington 208 carbon coater. The study results showed significant effect of microdischarges in the DBD cell on elemental composition of surface films deposited on the fabric-based laminate surface.

Influence of the high voltage waveform on productivity of a plasma-chemical ozone generator on the basis of dielectric barrier discharge (DBD) is studied. Experimental studies were carried out using of two types of AC high voltage: at first, AC high voltage (the voltage effective value is equal to U 2=11 kV), representing continuous periodically repeating inharmonic structures with frequency f 2=400 Hz; secondly, pulsed high voltage with the amplitude equal to U p=20 kV, pulse width 50 ns, the pulse edge 20 ns and the pulse duration 2.5 ms (thus, the pulse repetition rate, in average, is equal to 400 Hz). For the second case, the productivity by ozone of the DBD cell is significantly higher.
