ATMOSPHERIC PRESSURE PLASMA JET IN ARGON GAS DRIVEN BY USING NEON SIGN TRANSFORMERS

Abstract

In this study, atmospheric pressure plasma jet  was generated by a high-frequency, high-voltage source modulated by a neon sign transformer. Neon transformers are compact, cost-effective, and have ability to generate high-frequency output voltage, which makes them particularly effective for generating argon-based plasma jets. The main focus is on evaluating the effects of continuous voltage modulation by the neon sign transformer on the electrical characteristics of atmospheric pressure plasma jets in Ar gas. It is found that alterations in the modulated voltage also alternate plasma intensity. Changes in voltage amplitude in each modulation cycle of the neon sign transformer leads to significant changes in the electrical characteristics of the plasma jets. Furthermore, an increase in voltage amplitude not only enhances plasma intensity but also corresponds to a nearly linear increase in power consumption and dissipation within the treated targets. By examining these parameters, the study seeks to provide insights into optimizing plasma generation for energy-efficient and high-performance applications in fields such as biomedical treatments, agriculture, and food safety.
