Compact high voltage pulse generator for DBD plasma jets

Abstract

Compact low-power high voltage pulse generator for DBD plasma jets was developed and assembled. There is a function of voltage pulse value and pulse repetition frequency regulation with the fascia control panel of the generator. The voltage amplitude can be set at the level of 0-6 kV. There are two frequency bands: 10-100 Hz and 0.1-1 kHz. The high voltage pulses of 12 μs duration have nanosecond rise and fall time 20 ns. The generator is powered by 220 V, 50 Hz. The overall dimensions of the device - 105×260×180 mm, its weight is less than 2 kg. The generator was successfully tested on DBD plasma jets. The average power up to 0.3-0.4 W was obtained in plasma depending on discharge electrode system.
