介质阻挡放电和大气压辉光放电的分析和仿真

Analysis and Simulation of Dielectric Barrier Discharge and Atmospheric Pressure Glow Discharge

鉴于介质阻挡放电(DBD)和大气压下的辉光放电(APGD)都是非线性变化的负载,会给放电电源的设计带来很大麻烦,分别对这两种最有工业应用前景的低温等离子体技术进行了理论分析和仿真,讨论了表征放电特性的图形,指出了随着输入电压频率f的变化,DBD微放电脉冲的幅值将增大,而气隙上的电压Ug、介质上的电压Ud和外加电压U的关系保持不变。仿真和测量结果验证了理论分析的正确性。

Dielectric barrier discharge (DBD) and atmospheric pressure glow discharge (APGD) are the most prospective low-temperature plasma technology in industrial application. But they represent nonlinear capacitive type loads, which are rather difficult for designing the inverter. The analysis and simulation of them are done in this paper. Images of discharge properties are presented and discussed. Point out that the discharge current increases as the frequency of input voltage increases, but the relationships of Ug, Ud and U don't change. Simulated and measured results are used to verify the theoretical analysis.
