Simulation of dielectric barrier discharge using SIMULINK

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.
