A high-voltage pulse generator for corona plasma generation

Abstract

This paper discusses a high-voltage pulse generator for producing corona plasma. The generator consists of three resonant charging circuits, a transmission line transformer, and a triggered spark-gap switch. Voltage pulses in the order of 30-100 kV with a rise time of 10-20 ns, a pulse duration of 100-200 ns, a pulse repetition rate of 1-900 pps, an energy per pulse of 0.5-12 J, and the average power of up to 10 kW have been achieved with total energy conversion efficiency of 80%-90%. Moreover, the system has been used in four industrial demonstrations on volatile organic compounds removal, odor emission control, and biogas conditioning.
