Abstract

A device for generating a high pulse voltage comprises a source of high constant voltage, an inductive load, two controllable switching devices, a controllable switch, and also, connected in series, a capacitor, a diode and an additional controllable switch, and a controllable pulse duration converter for converting the duration of pulses from a control circuit. The result is a reduction in the level of interference emitted into the environment.
