Generators of high-voltage pulses with a repetition rate of 50000 pulses per second

We study the schematic and mechanical features of frequency (∼50000 pulses/s) generators of high-voltage (up to 10 kV) pulses of the microsecond range. We analyze (with the purpose of decreasing energy consumed from the power network) the energy transfer process from a low-voltage discharge circuit (with insulated-gate bipolar transistors as commutators) by means of a step-up pulse transformer to the load. We implement the design of a generator with pulse front sharpening in the load (into a reactor with pulsed corona discharge) using a multigap air discharger. The maximum achieved pulse repetition rate with a sharpened front was ∼27 000 pulses/s and a voltage of ∼3 kV.
