| 摘 要： | 采用μs振荡脉冲电源激励同轴电极结构产生空气中介质阻挡放电(DBD)，通过电压-电流波形的测量及发光图像拍摄研究了放电特性，计算得到了放电功率及传输电荷量等重要放电参量，研究了电压幅值、气隙距离对放电特性及放电参量的影响，在分析放电机理的基础上对实验结果进行了解释。结果表明:μs振荡脉冲电源激励下,DBD平均放电功率可达上百W，传输电荷量可达几千nC；增大电压幅值和减小放电气隙距离能获得更剧烈的放电，平均放电功率和传输电荷量均增加。

| Abstract: | The dielectric barrier discharge(DBD) in atmospheric air is generated with coaxial dielectric structure driven by a microsecond oscillatory pulse power supply. The discharge characteristics of DBD are studied by measurement of the voltage-current waveform and capture of the lighting emission images, and the important discharge parameters such as transfer charge and discharge power are calculated. The influences of applied voltage amplitude and air gap distance on discharge characteristics and parameters of DBD are studied, and the experimental results are explained based on the analysis of the discharge mechanism. Results show that the DBD driven by a microsecond oscillatory pulse power supply consume more discharge power and transfer larger amount of charge, and the average discharge powe |
