Properties of gliding arc (GA) reactors energized from AC/DC/AC power converters

Industrial plasma reactors design requires knowledge of their characteristics at different conditions of power supply system. Gliding arc plasma (GAD) characteristics are very sensitive either on these parameters or the properties and dynamic of the plasma gas (velocity, kind of gas and its composition). Paper presents the results of investigations of the atmospheric pressure low temperature GAD plasma properties controlled by a power electronic inverter and by a transformer type power supply system. Measurements are performed for discharges in argon, nitrogen and their mixtures in three-electrode plasma reactor. AC/DC/AC inverter has operated as a current and voltage source.
