Ozone has many applications in various fields with an advantage of low environmental load, i.e., water treatment, sterilization, deodorization, bleaching, etc. While the dielectric barrier discharge (DBD) is mainly used for practical ozone generator, the various discharge methods have been studied to achieve higher yield and higher concentration of ozone generation in recent years. This study is carried out to compose ozone using a Blumlein type pulse forming network (B-PFN) as a discharge power source combined with the ordinary DBD type ozone generator. The ozone generator is equipped a pair of coaxial cylinder electrodes. The inner electrode is stainless steel cylinder and is applied pulsed voltage. The outer electrode is covered by glass lining of inner surface of electrode and is act as earthed electrode. This generator gives maximum ozone concentration of about 57g/Nm3 by negative polarity and maximum ozone yield of about 900g/kWh by positive polarity. These results are compared with other results using pulsed power discharges. We also investigated temporal variation of ozone concentration, related to “Ozone zero phenomena”.
