摘要
An atmospheric pressure arc plasma jet sustained using pulsed DC power is studied by examining its appearance using a high-speed camera and measuring current and voltage waveforms at the powered electrode using current and high-voltage probes. Given the seemingly uniform in time visual appearance, the high-speed camera images show that the plasma jet undergoes some transition within each power cycle. Current and voltage waveform characteristics suggest that such a transition is most likely due to a glow-to-arc mode transition, The occurrence of this transition is controlled by the plasma physics rather than by the duty cycle of the pulsed power.
