【摘要】 建立基于电压控制电流源(voltage-controlled current source,CCS)的工频介质阻挡放电(dielectric barrier discharge,DBD)动态仿真模型和实验装置,对空气中平板电极结构DBD进行仿真与实验研究。可通过分别计算仿真与实验得到的电压电流波形和电压电荷Lissajous图形得到DBD的电气参数,二者的定量比较验证了仿真模型的准确性,利用仿真模型和实验装置对不同外加电压幅值、阻挡介质厚度与介电常数条件下DBD功率的变化情况进行研究和定量比较,并从理论上对所得的仿真计算结果与实验测量结果的变化规律进行定性分析。研究结果表明,基于CCS的工频DBD动态仿真模型能够反映放电的真实情况,仿真计算所得到的不同条件下DBD的放电功率与实验测量所得到的值是吻合的,且两者的变化规律均与定性理论分析是一致的。更多还原

【Abstract】 A dynamic simulation model which based on the voltage-controlled current source (CCS) for power-frequency dielectric barrier discharge (DBD) and the experiment system for generating DBD are established to study the plane-to-plane configuration DBD in air by simulation and experiment. The electrical parameters of DBD are calculated from the simulated and measured voltage-current waves and voltage-charge Lissajous figures, respectively, and the coherence of the quantitative comparison between them confirms the validity of the simulation model. The change of the discharge power of DBD with amplitude of applied voltage, thickness and dielectric permittivity of the barrier is studied and quantitatively compared by simulation and experiment, and their change trends are qualitatively analyzed from theory. Results show that the dynamic simulation model based on CCS can reflect discharge characteristics of DBD more truly. The discharge power calculated from the simulation and measured from the experiment are well coherence and both change trends are in accordance with the theoretical qualitative analysis.更多还原
