“…The energy is supplied for the micro discharges, where oxygen molecules break into a single atom and combine with other oxygen molecules to form ozone. The advantage of using a lower applied voltage is the opportunity to have ozone generators using nonconventional dielectric materials that have much lower dielectric breakdown voltage, such as mica, alumina ceramic, thin enamel, and polymer layers materials [4].…”

Ozonizer is a method used for sterilization and food preservation by utilizing ozone produced from plasma discharge. The effective way of obtaining ozone is to use dielectric barrier discharge (DBD) plasma. The manufacture of a controlled ozonizer chamber system is important to result in effective and efficient performance. The aim of this study is to design and optimize the ozone chamber parameter using pulse width modulation (PWM). The system design is added with the Arduino Mega 2560 microcontroller and the L296N motor driver as an ozone generator radiation controller by changing the pulse width modulation to determine the ozone levels produced. The experimental results show that the ozone concentration increases by 50 % on average with increasing variations of the 10 % duty cycle (PWM) and the ignition time length. The optimum value is achieved on a 70 % duty cycle for 60 - 300 seconds, where the ozone level of 3 ppm is obtained and sustained for fruits/vegetables sterilization and preservation application.

“…Conversely, in the silent discharge technique, the inception voltage required for a given ozone concentration is lower. This characteristic results in reduced power and voltage demands from the pulse generator [11]. In terms of efficiency, for a constant applied voltage and DBD chamber size, silent discharge achieves close to 95 % ozone production efficiency, a notable contrast to the 40 % efficiency observed in the corona and pulse streamer discharge.…”

Usage of ozone is an effective way of treating wastewater, and the silent discharge technique is one of the most efficient and reliable methods for ozone production. Ozone is generated in a Dielectric Barrier Discharge (DBD) chamber through the silent discharge technique and is powered by a high voltage (in the range of −2.5 kV to −5 kV) pulse generator. The pulse generator has two conversion stages, i.e., a high-frequency pre-processing stage and a pulse-frequency postprocessing stage. In a high voltage pulse generator, a significant amount of energy from the input is utilised by the converter's parasitic capacitance and leakage inductance, which reduces the energy delivered to the load for each pulse cycle. This paper proposes an energy-based analysis exploring the potential usage of the flyback converter-based high voltage pulse generator for an application with power requirements under 150W, and water treatment is such an application. An energy-based approach is appropriate to describe the behaviour of the pulse generator in terms of circulating energy and energy exchanges in each stage and energy exchanges between the two stages (i.e. pre and post-processing stages). The proposed analysis is used to derive the essential parameters of the pulse generator and thereby arrive at an appropriate control scheme for the pre and postprocessing stages. The proposed energy-based analysis and the derived analytical expressions of the high voltage pulse generator are verified experimentally for a pulsed output voltage of −5 kV having a Pulse Repetitive Rate (PRR) of 1000 Hz and pulse width of 15 µs fed from a 12 V battery source.INDEX TERMS energy-based analysis, flyback converter, capacitive load, programmable pulsed high voltage, pulse power, resonant converter NOMENCLATURE
