Evaluation of characteristics of Multi-purpose Atmospheric Pressure Plasma Device*

The atmospheric pressure plasma (APP) doesn't stop at the industrial field, and application is also developed in the medical field. But commercialization is precedent to plasma medical equipment only by empirical fact, and there're many indefinite points in a mechanism of revival in biomedical tissue. In generally, the flow of APP source includes active oxygen species (ROS) such as ozone (O$_{\mathrm{3}})$, hydroxyl radical (OH), hydrogen peroxide (H$_{\mathrm{2}}$O$_{\mathrm{2}})$, nitric oxide (NO), nitrite (NO$_{\mathrm{2}})$, and active nitrogen species (RNS), etc. generated around the plasma flow. In view of the above background, in this research, we are developing a prototype and evaluation of an atmospheric pressure plasma source for the purpose of controlling radical species. Previous experiments confirmed that it is possible to easily change the plasma product by controlling the plasma parameters. In this presentation we will report on the consideration of the power supply unit.
