Abstract
A review of the supply systems of non-thermal plasma reactors (NTPR) with dielectric barrier discharge (DBD), atmospheric pressure plasma jets (APPJ) and gliding arc discharge (GAD) was performed. This choice is due to the following reasons: these types of electrical discharges produce non-thermal plasma at atmospheric pressure, the reactor design is well developed and relatively simple, the potential area of application is large, especially in environmental protection processes and biotechnologies currently under development, theses reactors can be powered from similar sources using non-linear transformer magnetic circuits and power electronics systems, and finally, these plasma reactors and their power supply systems, as well as their applications are the subject of research conducted by the author of the review and her team from the Department of Electrical Engineering and Electrotechnology of the Lublin University of Technology, Poland.
Highlights
Non-thermal plasma, commonly known as “cold”, has been used for almost two hundred years.Its main source in the nineteenth century was arcing, and the first application, already at the beginning of the nineteenth century, arc lamps, which illuminated the streets of the world metropolises, such asParis, London and New York [1,2]
Transformer power supply systems for gliding arc reactors can be equipped with separate, high-frequency, ignition systems, made in the form of electronic modules giving an ignition voltage with a frequency (20–40) kHz, which increases the possibility of occurrence of ignition and at the same time reduces the size of the ignition system [5,34,36,43,47]
Non-thermal and non-equilibrium plasma can be generated by electrical discharges of almost any type
Summary
Non-thermal plasma, commonly known as “cold”, has been used for almost two hundred years. Research in the field of technological applications of plasma concerns two main issues: New solutions of plasma reactors (PRs) and electric discharges used in them, in which plasma, with the required plasma-chemical parameters and high time-space effectiveness, will be produced efficiently at atmospheric pressure [31,32,33,34]; Efficient and controllable plasma reactor’s power supply systems with a wide range of changes in the properties (voltage shape and frequency, range of regulation), which are an inseparable part of the plasma-chemical installation that determines industrial implementation [35,36,37,38,39,40,41,42,43,44,45]. The selected applications of the discussed systems, which were studied and implemented by the author of the article and her research team, has been presented
