The aim of this study is to investigate the current pulses and their effects on ozone generation during the process of ozone production in oxygen-fed dielectric barrier discharge. The experimental results show that there are large numbers of current pulses in the positive half-period of the current waveform but no obvious in the negative half-period. Moreover, the number of the current pulses in an AC cycle increases roughly linearly from 200 to 882 when applied voltage increases from 5 kV to 9 kV at 5 kHz. The number of these current pulses is almost independent of frequency. And these substantial current pulses occurring can be attributed to strong partial discharges generated in discharge gap may mainly resulting from the rough dielectric surface. Besides, these current pulses play an important role in the discharge characteristics and they are not in favor of ozone generation. The discharge power within current pulses is 1.47–1.76 times higher than the discharge power without current pulses and the ozone yield within current pulses is much lower than the ozone yield without current pulses. The decrease of ozone yield within current pulses is slightly more remarkable than the one without current pulses, because the discharge power within current pulses enhances more quickly.

本研究的目的是研究氧馈电介质阻挡放电中臭氧产生过程中的电流脉冲及其对臭氧产生的影响。实验结果表明，电流波形的正半周期有大量电流脉冲，而负半周期则不明显。此外，当施加的电压在 5 kHz 下从 5 kV 增加到 9 kV 时，AC 周期中的电流脉冲数大致线性地从 200 增加到 882。这些电流脉冲的数量几乎与频率无关。而这些大量电流脉冲的出现可归因于放电间隙中产生的强局部放电，可能主要是由粗糙的电介质表面造成的。除了，这些电流脉冲在放电特性中起着重要作用，它们不利于臭氧的产生。电流脉冲内的放电功率比无电流脉冲的放电功率高1.47-1.76倍，电流脉冲内的臭氧产量远低于无电流脉冲的臭氧产量。电流脉冲内臭氧产量的降低比没有电流脉冲的臭氧产量的降低稍微显着，因为电流脉冲内的放电功率增加得更快。
