Influence of dielectric parameters on temporal behavior of dielectric barrier discharge
介质阻挡放电中电介质参量对放电时间特性的影响

The Influences of different temperature and materials of dielectrics on temporal behavior of dielectric barrier discharge in argon at atmospheric pressure are studied by using a device with asymmetric dielectric parameters. It is found that the temporal waveform of discharge current in each half cycle is almost the same at lower applied voltage, whereas the number of discharge current pulses is different in half cycles of different polarity at higher applied voltage. The analysis shows that both temperature and material of dielectrics affect the accumulation of wall charges, resulting in the change of temporal behavior of discharge.
