“…SHF power supplies are large-size and lowefficiency. Applying of HF sine voltage gives the opportunity of use of small-size power supplies, but in this case gas temperature can be lower than 40 ∘ C at high flow rate of working gas (> 3 L/min) [3]. Authors of works [4][5] produced high efficiency of excimer DBD lamps due to feeding of discharge by short pulsed voltage.…”

Low-temperature plasma has been successfully used in medicine for last 15 years.Cure of purulent wounds by means of discharge plasma with low gas temperature is a new method of medical drug-free treatment. A result of investigation of atmospheric pressure helium plasma-jet excited by capacitive discharges at various method of excitation is presented. Homogenous discharge of plasma jet and 34 ∘ C of gas temperature at helium flow 0.5L/min was achieved at short pulsed voltage excitation.

“…At lower frequencies, a high-frequency sine voltage has the benefit of requiring smaller-sized power supplies, currently using linear amplifiers. In this case, however, gas temperatures below 42 °C can be achieved at high working gas flow rates only (>3 L/min) [10]. Below, we consider modern power electronic circuits using switched solid-state semiconductors as a solution.…”

This article presents an experimental study of a DBD-driven plasma jet system. The aim of the study is to design a whole system (the jet reactor, its electrical power supply, and a gas-feeding apparatus) suitable for biomedical applications. The article describes the test bench developed for this purpose and discusses the parameters it controls. The measurements show that the studied solutions can be used to control critical parameters such as the jet temperature and dimensions. The best results were obtained for a bipolar short-pulse voltage power supply in the 10–20 kHz frequency range and for a series resonant inverter current power supply operated in “burst mode”, allowing low-frequency modulation.

“…High voltage applied to the ring electrodes 2 ignites the gas discharge plasma inside the tube 1, and the gas flow 6 pushes the plasma out in the form of a jet 5. and inefficient. Sine HF voltage has the benefit of using power supplies that are more compact, but in this case gas temperatures lower than 40 °C can only be achieved at high flow rates of working gas (>3 L/min) [7].…”

Investigation of Nonthermal Plasma Jet Excitation Mode and Optical Assessment of Its Electron Concentration

The results of a study of a plasma jet of atmospheric-pressure helium driven by a capacitive discharge using sine and pulsed modes of excitation are presented. The homogeneous discharge of a multi-channel plasma jet at gas temperature of 34 °C and helium flow rate of 0.5 L/min was achieved with short pulse excitation. A digital holography method is proposed to estimate a basic plasma parameter, i.e., its electron concentration. An automated digital holographic interferometry set-up for the observation and study of a nonthermal plasma jet in a pulse mode is developed and described. The synchronization features of recording devices with the generation of plasma pulses are considered. The electron concentration of the plasma jet is also estimated. The disadvantages of the proposed technique and its further application are discussed.
