臭氧的生产是放电最典型的工业和商业应用之一。为了卫生和环保的灭菌，臭氧的需求增加。使用脉冲功率放电产生臭氧会在流光放电头周围施加电子加速。然而，反应器的故障常常限制高效生产。应根据反应器的尺寸控制脉冲形状。另一方面，较窄的反应器有利于在放电区域获得高能量密度。显然，脉冲缩短是有效的方法之一。纳秒脉冲电源电压适用于臭氧生产。短脉冲由短脉冲形成线和高压短气体开关组合产生，并以线到缸的配置供给到反应器。本文讨论了脉冲形状、反应器尺寸和配置以及氧气流速对臭氧产生的影响。目前获得的臭氧产生效率为350克/千瓦时。
Production of ozone is one of the most typical industrial and commercial applications of electrical discharge. The demand of ozone increases for for wholesome and environment-friendly sterilizations. The production of ozone using the pulsed power discharge applies the electron accelerations around the head of streamer discharge. The breakdowns in reactor, however, often limit the efficient production. The pulse shape should be controlled for dimension of the reactor. On the other hand, the narrow reactor is preferable to obtain high energy density in the discharge region. It is clear that a pulse shortening is one of the effective approaches. The nanosecond pulsed power voltage applies for ozone production. The short pulse is generated from a combination of a short pulse forming line and short gas switch with high pressure, and supplies to the reactor with a wire-to-cylinder configuration. The effects of the pulse shape, dimension and configuration of the reactor and flow rate of oxygen gas on ozone production are discussed here. The efficiency, producing ozone, of 350 g/kWh is obtained at present.
