At low pressure, cold plasmas are used for a wide range of applications such as coating, flow control, or microelectronics. Currently, this industry requires expensive vacuum systems which consume energy and time, and therefore it is very appealing to develop similar processes at atmospheric pressure. Under this condition, dielectric barrier discha...

This paper presents the analysis of a Series Resonant Inverter for Dielectric Barrier Discharge (DBD) applications, operating in discontinuous current mode. The study of different factors that can improve the efficiency and behavior of the converter are presented. First, the implementation of the converter is studied with two possible locations of...

A new transformerless power supply for DBD application is presented here. The power supply is built with 10kV SiC MOSFET. This high voltage switches allow holding the high voltage required by the DBD. An analytical study of the converter's operation is presented to deduce the power transmitted to the DBD. A comparison between the experimental and t...

Dielectric Barrier Discharge (DBD) are able to produce cold plasma, used for a wide range of applications. To ignite and maintain the plasma, the high voltage required is generally obtained through a step-up transformer, which is the weak part of the power supply, considering the reliability, the efficiency and the ability to control the discharge....
