Abstract
The era of evolution in power electronic systems has led to a widespread displacement of power supplies operating at mains frequencies. Switched-mode power inverters offer possibilities incomparably higher than mains transformers. These trends have also entered into plasma technologies, including GlidArc plasma processing. The article presents the use of an inverter power supply for a miniaturized GlidArc. It is a demonstration of using a push–pull topology in an unusual application. A special part is devoted to parasitic phenomena in the inverter and the implementation of switching overvoltages as a way of improving the ignition parameters of the power supply. The results of the tests with a plasma reactor in air conditions as a process gas are also presented.
Highlights
A gliding arc discharge (GAD) plasma reactor is a special source of non-thermal plasma
With the mains frequency power supply, a spark discharge appears, followed by an arc column, whose volume and length increases gradually due to the fast gas flow and electrodynamic forces
There is a significant imbalance of electron temperature and average gas temperature, due to which a source of high-energy electrons used in plasmochemical processes is obtained
Summary
Featured Application: The publication is related to the properties of an atypical power supply. This source is used to supply two-electrode micro gliding arc discharge (GAD) reactors (μGAD). The principle consists in applying parasitic phenomena, whose parameters are limited in other power converters
