提出了一种利用压电Transformer（PT）产生介质阻挡放电（DBD）的新方法。利用电荷耦合器件（CCD）摄像机观测了微放电的时空变化，并进行了讨论。作为DBD在等离子体反应器中的实际应用的一个例子，开发了使用PT的臭氧发生器，并在空气和氧气中进行臭氧生产。在空气和氧气中分别获得了3.38和20.3 g/Nm 3的最大臭氧浓度。臭氧发生器可以设计成紧凑的结构，并以低施加电压驱动，因为PT既用作高压发生器又用作放电电极。
A novel generation method of a dielectric barrier discharge (DBD) using a piezoelectric transformer (PT) is proposed. Spatio-temporal variations of microdischarges were investigated and discussed on the basis of the observations using a charge-coupled device (CCD) camera. As an example of a practical application of the DBD to a plasma reactor, an ozonizer using the PT was developed and ozone productions were performed in air and oxygen. Maximum ozone concentrations of 3.38 and 20.3 g/Nm3 were obtained in air and oxygen, respectively. The ozonizer can be designed in a compact configuration and driven with low applied voltages because the PT serves as both a high-voltage generator and a discharge electrode.
