Energy-Controlled Atmospheric-Pressure Micro-Plasma Using Multistep External Ballast Capacitors

In this study, atmospheric-pressure (AP) micro-plasma discharge with a controlled energy has been developed. Using multistep external ballast capacitors, a dc voltage higher than the breakdown voltage of the plasma can be applied to an electrode. Because the stored energy at the external capacitor is injected directly into the plasma, the plasma is controlled by the stored energy of the external b...
