Experimental study of the dielectric barrier discharges electromagnetic noise

Popis výsledku v původním jazyce

For the surface dielectric barrier discharge in the air, we investigated the effect of the discharge voltage, sinusoidal or square-driving voltage waveforms, and one or three strips-driven electrodes on spectra of the electric component of emitted electromagnetic waves within the frequency band up to 500 MHz. Besides the spectra, we monitored the discharge voltage, current, and voltage drop on the measuring capacitor to show a correlation among these quantities. We found that the most intense emission, independent of the discharge voltage, voltage waveforms, and the number of strips of the driven electrode, is in the range of frequencies from 30 to 80 MHz, which corresponds to the very high-frequency band. Our results indicate that the increase of the discharge voltage increases the power level of the emitted radiation, but it does not substantially affect the frequencies distribution in emitted spectra. On the other hand, the driving voltage waveform influences discharge emissions. The power level of this emission for the whole frequency spectrum and both types of driven electrodes is higher for the square-driving voltage than for the sinusoidal driving voltage. Finally, the change in the number of strips of the driven electrode causes differences in the power level and frequencies of emitted radiation.
