Abstract: The invention relates to a pulse generator comprising an inductor that is intended to store energy that is delivered, during a charge phase, by a DC voltage source to two power supply terminals of the generator, and to transfer the energy to the dielectric-barrier discharge device during a discharge phase via a transformer, the generator further comprising: an arrangement of a first and of a second circuits in series that are connected at a node N of the generator; the first circuit comprising two branches, one of the two branches comprising the inductor, and the other branch comprising a diode and the transformer, the secondary being connected to the dielectric-barrier discharge device; the second circuit comprising a controlled switch.
