“…When the electrode spacing is between 0.5 and 2 mm, the pulse modulation power will change slightly with the variation of the electrode gap. The choice of spacing has deviated from the theme of this paper, so we only explain here: this work finally chooses the electrode gap of 1 mm, which is the common gap for arc ignition [5].…”

“…Direct-current (DC) arc plasma technology, due to high temperature and chemical activity properties [1,2], has wide application value in high-temperature chemical fields such as nano-material preparation [2], CO 2 reforming [3], hazardous waste treatment [4], and device combustion [5]. However, due to the poor energy selectivity of the plasma itself, it always has the fatal problem of low electron temperature and low efficiency in the chemical industry [6].…”

Direct-current (DC) arc plasma has great application value in the field of chemical industry, but it has the problem of low energy efficiency. Facing the requirement for improving the energy efficiency of the arc, this paper proposes a unique method of Pulsed Modulated Arc (PMA). This method uses high-frequency pulses and reduces the arc current to improve the control of electron temperature. The electrical characteristics, optical characteristics and products are tested. The test results show that during the PMA process, all of the experimental results which include voltage, current and light will significantly increase. These results are analyzed from the perspective of functionality, repeatability and energy conversion. The analysis results show that although the PMA method does not show good parameter consistency, it has potential application prospects because it increases the energy conversion rate by 4.5% and 8% from the perspective of light and products respectively.
