Analysis of pulse power converter for plasma application

Atmospheric pressure plasma using a dielectric barrier discharge (DBD) reactor has been widely used for the surface treatment of materials, pollution abatement, disinfections, etc. A high voltage power supply is needed, however, to generate plasma in atmospheric pressure circumstances. Especially, it is widely known that the pulsed voltage can generate plasma with better quality compared to the voltage with a sinusoidal waveform. In this paper, an analysis of the pulse power converter including a dielectric barrier discharge (DBD) reactor was performed to obtain design information regarding the converter system which generates the pulsed high voltage. A pulse power converter system was fabricated and applied to a DBD reactor. The results of the simulation and experiment on the converter system that was applied to the DBD reactor are presented in this paper.
