Differential feed dielectric barrier discharging low-temperature plasma device

This invention relates to a low temperature plasma device for blocking discharge by a differential feeder medium including a difference output high voltage supply, two high voltage electrodes, in which, the output of the differential output high voltage supply is connected with the two high voltage electrodes, a layer of medium is covered on one of the electrodes or set at any place between the two electrodes, and the gas between them is the load and the voltages to the earth of the two output ends of the supply connected to the two electrodes are equal or almost equal, the phase difference is 180 deg. or approaching to 180deg, which can generate DBD of large discharge clearance for producing large volume of gas discharge low temperature plasma and reduce the supply output voltage necessary for gas discharge.
