介质阻挡放电中的能量转换过程研究

研究了介质阻挡放电过程中的电流强度、电场强度以及电荷分布的演变规律，并对能量转换性质进行了分析.研究结果表明，在一个放电脉冲过程中，外加驱动电源所作的功、电场能量的增量均与起始时刻的壁电荷密度有关，而气体中放电电流所作的功即沉积于气体中的能量与起始时刻的壁电荷密度、放电电流的具体波形无关. 关键词： 介质阻挡放电 壁电荷 动力学过程 能量转换

Investigation on power transfer in dielectric barrier discharge

The current density， field intensity and charge distribution in transient dielectric barrier discharge have been investigated. The energy transfer during the discharge has also been analyzed. The results showed that both the energy from the applied high-voltage source and the energy increment of the electric field were related with the density of wall charge. However, the work done by the discharge current in the gas region is independent of the density of wall charge and the kind of current waveform.
