Power Systems of Plasma Reactors for Non-Thermal Plasma Generation

Abstract

Recently, many different plasma sources are being investigated for exhaust gases treatment, odor abatement, VOC removal, soil conditioning, surface decontamination or tissue disinfection and sterilization. Among many different plasma reactors investigated in laboratories, gliding arc discharges (GAD), dielectric barrier discharges (DBD), pulsed discharges (PD), atmospheric pressure glow discharges (APGD) and atmospheric pressure plasma jets (APPJ) seem to be the most promising for high pressure low temperature applications. They can be designed as multi-electrodes’ high power system that can be used in environment protection processes, like decontamination of large surfaces and treatment of large volume of polluted gases, as well as small size and low power devices for biomedical applications, like plasma healing, disinfection and sterilization. Paper presents review of power supply systems for cold plasma reactors. Dielectric Barrier Discharge (DBD), Gliding Arc Discharge (GAD) and atmospheric pressure plasma jet (APPJ) reactors with their supply systems have been discussed from the point view of their characteristics, possibility to control power to the discharge and efficiency. Taking into account the plasma reactor characteristics and nature (nonlinear resistive and/or capacitive) different solutions of power suppliers have been presented: transformer type, AC/DC/AC inverter, RF-frequency system and frequency resonant inverter.

Cold plasma: a potential new method to manage postharvest diseases caused by fungal plant pathogens

“…AC to DC), inverters or other systems including radio frequency power systems as reviewed by Stryczewska et al . (). Further, CP may be generated using batteries or solar power (Li & Tanielian, ; Pei et al ., ).…”

Evaluation of Oxidative Species in Gaseous and Liquid Phase Generated by Mini-Gliding Arc Discharge

“…Since then, many studies have been performed on the diagnostics and the applications for purification and production of selected chemical compounds. In recent years, there have also been many publications on the use of GA in low-temperature applications due to its potential to produce a non-equilibrium plasma at atmospheric pressure [2,[4][5][6][7][8][9][10][11][12][13]. Du and Yan used GA with a mixture of distilled water and air to sterilize the isolated Escherichia coli, emphasizing the important role of the distance between the reactor and the sample [14].…”

AOTs and Solar Energy for Air, Water and Soil Treatment

“…Trials employing usage of electrical discharges, ozone alone or combined with AOTs were performed for the treatment of soil and plants by international research groups [6][7][8][9][10][11][12][13][14]. Application of AOTs helps to preserve natural structure of the soil, prevents its acidification, leaching and releasing metallic compounds.…”

“…Set-ups for soil and plants' treatment were extensively described [6][7][8][9][10][11]22]. Fig.3 depicts proposed integrated ozonation installation that consists of three basic sub-systems: electric energy power system, ozone production system and air/water/soil treatment system.…”
