For better understanding the discharge mechanisms of dielectric barrier discharge and optimizing the design of discharge reactors

based on the analysis of micro-discharges process and equivalent circuit of DBD

a dynamic simulating model for DBD was established using SIMULINK.To reflect the discharge instance of DBD more truly

a voltage-controlled current source was adopt to simulate micro-discharge in DBD

and the influences of the ignition and extinction time and the attenuation of the amplitude of the micro-discharge were also taken into consideration in the model.The established model was used to simulate the DBD in air

and the electrical parameters

such as discharge current

gap voltage and Lissajous diagram etc.were calculated.The simulating results and analysis show that the established model can be used to simulate the DBD

and the results can reflect discharge situation of DBD more truly.
