摘要
为了解介质阻挡放电(DBD)的微放电电流脉冲的形成原理及微放电电流脉冲的特点与介质阻挡放电的均匀程度之间的关系,建立了一个双水电极DBD系统等效电路的仿真模型,模型电源采用直流调功(PAM)控制。仿真和放电实验研究结果表明:该DBD系统逐步提高逆变电路的直流输入电压时,电源的输出电压逐渐增大,但其基波频率基本不变;放电的正、负半周内,微放电电流脉冲的幅值逐渐增大,脉冲的数量逐渐增多,相邻的脉冲之间的间距逐渐减小,微放电的持续时间逐渐增加,斑图的数量也逐渐增加,放电的均匀性也逐渐增加。
To investigate the characteristics of DBD by analyzing the forming principle of micro-dieharge current pulse of dilectric barrier discharge（DBD） and the corelation between the characteristic of micro-discharge current and uniformity of DBD, we established a circuit simulation model aecroding to a DBD setup with two water electrodes,in which pulse amplitude modulation（PAM） was used in the controlling Scheme of the DBD power supply. The DBD setup was experimentally studied. The research results show that, according to the DBD setup, along with the gradul increase of input voltage of the power supply＇s IGBT inverter, the output voltage of the power supply gradually increases, however, the fundamental wave frequency of the output voltage of the power supply keeps relatively stable. In each positive or negative half period of discharge, the amplitude and the number of the micro-discharge pulses gradually increase, the time distance between each of the nebouring current pulses gradually decreases, and the duration of discharge and the number of the pattern formation gradually increases, thus the uniformity of DBD is gradually enhanced.
