A high-power generator of nanosecond pulses with an amplitude of up to 500 kV and a repetition rate of up to 50 Hz

详细

A pulsed-power high-voltage generator, which is combined with an electric-discharge chamber, is designed for selective disintegration of quartz raw minerals and other nonconductive natural and artificial materials. The main parameters of the generator are as follows: the voltage-pulse amplitude, up to 500 kV; the discharge-current amplitude, up to 30 kA; the duration of current pulses (the half-period an oscillatory discharge), 70–90 ns; and the pulse repetition rate, up to 50 Hz. The generator is characterized by a high efficiency, a long service life, the possibility of long continuous operation, and the fulfillment of the electromagnetic compatibility requirements. The experience of the operation of three constructed installations testifies to their high reliability: the number of accumulated pulses in a typical mode (450 kV, 20 Hz) exceeded 108 pulses without a repair or replacement of units.
