    Abstract:
    An experimental generator of microsecond pulses with an output current amplitude of ∼1 kA and an output voltage amplitude of ∼1 kV was developed. The generator is able to operate on a load whose electrical resistance changes significantly during operation. Under these conditions, the generator ensures high stability of output pulse energy and effectively uses energy that is reflected from the load. Using this generator, a high voltage generator with an output voltage pulse amplitude of ∼30 kV was developed. The high voltage generator is designed to be used in electric discharge technologies. The results of the experiments are given in which the high voltage generator produced discharges in water at a repetition rate of 500 Hz. The amplitude of the discharge current pulse was ∼600 A, and the pulse rise time was ∼150 ns.
