“…Many experimental and theoretical studies or simulations have been presented. Some these include electrical characteristics, the transition between filamentary and homogeneous discharge modes, comparison of high-voltage ac and pulsed discharge and so on [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33]. Pulsed power generators, however, vary widely in performance according to load requirements, different results may be obtained from using various pulsed power generators and kinds of discharge configurations [4-6, 13, 14, 17, 19, 21, 29, 31].…”

“…Furthermore, it was observed that the secondary discharge at the falling edge depended on surface properties of the dielectric barrier [25]. The driving power supply and discharge configuration are the key factors determining discharge characteristic [26][27][28][29][30][31][32][33][34][35]. APGD or glow-like homogeneous discharge can be produced by various pulsed power source, such as inductive energy storage pulsed power applied to a needlearray electrode in nitrogen [26], sphere-to-plane discharge configuration excitated by a decay pulse source using double spark gaps [27], time-variable negative pulses used in two-planar electrodes [28].…”

Dielectric barrier discharge (DBD) excitation by unipolar high voltage pulses is apromising approach for producing non-thermal plasma at atmospheric pressure. In this study, a magnetic compression solid-state pulsed power generator was used to produce repetitive nanosecond pulses for the excitation. The DBD is created using two liquid electrodes. The electrical characteristics of the discharge voltage and current are illustrated under different experimental conditions. The nanosecond-pulse discharge current is of the order of tens of amperes. This differs from common DBD current excitated by high-voltage ac sources. Compared with the characteristics of two current pulses corresponding to two discharges for unipolar pulsed-excitation, the secondary discharge in this study is minor owing to the pulsed power and discharge configuration. Under the experimental conditions, the luminous emissions from the front and side views of the liquid electrodes show that no filament is observed and the discharge is homogeneous and diffuse in the whole discharge region. The effects of applied voltage amplitude, repetition rate, and air gap spacing on the discharge characteristic are investigated. The discharge mode does not change with the variation of the investigated parameters. A comparison of high voltage ac and nanosecond-pulse excitation is also presented. In addition, discussion of the experimental results is presented. Index Terms-Gas discharge; dielectric barrier discharge; pulsed power; nanosecond pulse; magnetic compression; repetition rate; atmospheric pressure air; non-thermal plasma; discharge mode; homogeneous discharge; atmospheric pressure glow discharge.

“…Commonly used materials are glass and alumina ceramic. Due to the thickness, they exhibit high dielectric breakdown voltages [25], [26]. Theoretically, the initiation voltage, i.e., the voltage that initiates the ozone generation, is close to its breakdown voltage; for a typical chamber using glass as dielectric with discharge gap of 1 mm, the initiation voltage is about 10-20 kV [4], [27].…”

Abstract-This paper describes the analysis and design of an LCL resonant power supply for ozone generation. The main advantage of the proposed topology is the absence of high-voltage transformer; the high voltage gain is achievable by means of doubleresonance phenomena. Furthermore, the bandwidth is wider than the ordinary LC and its phase difference is constant over specific frequency range; as a result, an open-loop operation can be implemented. The complete analysis and design procedure of the power supply is presented. The design procedure is verified by implementing the power supply to drive a dielectric barrier discharge prototype ozone chamber. The hardware results are found to be in close agreement with simulation and thus justify the validity of the design procedures. The proposed circuit is suitable for portable ozone power supply fed by low-voltage source such as battery or photovoltaic module.Index Terms-Dielectric barrier discharge (DBD), full-bridge inverter, high-voltage power supply, LCL resonant circuit, ozone generation.
