A pulse generator produces a voltage pulse for an inductive or capacitive load, in particular for an electrostatic dust extractor, having an energy-storage capacitor which is connected in series with a controllable switch. The switch is self-opening at the zero crossing of the current flowing to the load, in a series of tuned circuits. The energy-storage capacitor is discharged to the load by closing and opening the controllable switch in a single discharging process during only one half oscillation period of the series tuned circuit.
