The influence of barrier on dielectric barrier discharge

A new method is presented for measuring the electric parameters in dielectric barrier discharge (DBD), and the effect of barrier on discharge is investigated. Results show that the number of discharge current is variable in different half period of applied voltage, and the current pulse width is in the range of 160 to 280ns. The discharge power increases monotonously with the applied voltage, and the maximum power is 22.62w, which corresponding power density of 5.76w/cm3. The electric field in the gas gap decreases monotonously with the increase of gas gap, and the optimum work condition is proposed in DBD.
