  • Patent number: 11351556
    Abstract: The invention relates to a method for operating a high-voltage pulse system (1), preferably a system (1) for the fragmenting and/or weakening of material (2) by means of high-voltage discharges, with an energy store (3) for providing the energy for the high-voltage pulses and a charging device (4) for charging the energy store (3). According to the method, in the intended high-voltage pulse operation, a sequence of high-voltage pulses is generated with the system (1) and thereby the energy store (3) is discharged completely at each high-voltage pulse and is only after the expiry of a charging pause (LP) recharged again for the next high-voltage pulse by means of supplying charging energy with the charging device (4). By means of the operating method according to the invention, a time window is created between two successive high-voltage pulses each, in which the energy store(s) are substantially completely discharged and no charging-voltage is applied.
