Claim of US Patent No. 10,462,889

1. Electrical pulse generator intended to power a dielectric-barrier discharge device, the generator comprising an inductor 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 said energy to the dielectric-barrier discharge device during a discharge phase by the intermediary of a step-up 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 parallel branches, one of the two branches comprising the inductor, and the other branch comprising, in series, a diode connected by its anode to the node N, and by its cathode to the primary circuit of the step-up transformer, the secondary circuit of the step-up transformer, the secondary circuit of the step-up transformer being intended to be connected to the dielectric-barrier discharge device,
the second circuit comprising a controlled switch of which the closing and the opening control, respectively, the charge and discharge phases.
