Abstract. The description of the powerful generator of unipolar pulses having the charger connected to power capacitors and the thyristor switch, discharging the capacitors to the low ohm load is presented. In order to reduce the main power, the charge exchange device on the base of thyristor connected antiparallelly in thyristor switch is introduced in the scheme. To realize the possibility of pulse amplitude control and increase in its capacity two irreversible thyristor transformers are used in charger instead of an unregulated direct current source. These thyristor transformers are switched on in series and in unidirectional way. They permit to obtain the regulated voltage at power capacitors. In order to optimize the capacitor charging process a two-circuit system of subordinate regulation of pulse generator parameters with external voltage control circuit and internal control – current capacitor charge. The model of the suggested generator is implemented in the «Matlab, Simulink» medium. The model is adequate to the real pulse generator used in SibSIU for investigation of electrostimulated plastic deformation of metals and alloys. The developed model permitted to improve the technical parameters and device operation regimes. The considerable mains power decreases as well as possibility of capacitor charge voltage control up to 600 V in the range of pulse repetition frequency 400 Hz are the advantages of updated generator in comparison with the analogues. The generator can be used in industry, in particular, rolling production for hard deformed steel wire drawing.
