Simulation and experimental studies on discharge characteristics of multiple pulse homogeneous dielectric barrier discharge

In order to simplify experiments, to optimize the reactor design, and to expand the range of the homogeneous dielectric barrier discharge, we developed a dynamic simulation model for multiple pulses homogeneous dielectric barrier discharge (DBD). In this model, an equivalent electrical model in which a voltage controlled current source (VCCS) is used to simulate homogeneous discharge is adopted, and a switch control module is established to control the VCCS to achieve the functions of adjusting of the number of the pulses. The electrical characteristics of the plane-parallel configuration homogeneous DBD in Ne at atmospheric pressure is studied using the model, and the voltage and current waveforms and Lissajous figures under different conditions are obtained. The electrical characteristics of homogeneous DBD at different voltage amplitudes are also experimentally studied, and the simulation results and experimental results are compared. It is shown that the simulated voltage and current waveforms and Lissajous figures are consistent with experimental ones. The dynamic behavior of the discharge parameters, such as gas gap voltage, discharge current, discharge consumed power, and transported charges which can not be measured in the real discharge process can be calculated with the electrical simulation model. From the voltage-current characteristics curves obtained from simulation, it is known that, except the first discharge current pulse which represents the translation from Townsend discharge into glow discharge, the rest discharge current pulse are all glow discharge.
