Title (EN) ELECTRICAL PULSE GENERATOR
(FR) GENERATEUR D'IMPULSIONS ELECTRIQUES
Abstract:
(EN) The invention relates to a pulse generator (10) comprising an inductor (Lstock) that is intended to store energy that is delivered, during a charge phase, by a DC voltage source (30) to two power supply terminals of the generator (10), and to transfer said energy to the dielectric-barrier discharge device (20) during a discharge phase via a transformer (Ts), the generator (10) further comprising: - an arrangement of a first (40) and of a second (50) circuits in series that are connected at a node N of the generator (10); the first circuit (40) comprising two branches (41, 42), one of the two branches (41) comprising the inductor (Lstock), and the other branch (42) comprising a diode (D1) and the transformer (Ts), the secondary circuit (Ts2) being connected to the dielectric-barrier discharge device (20); - the second circuit (50) comprising a controlled switch (T1).
(FR) L'invention concerne un générateur d'impulsions (10) comprenant une inductance (Lstock) destinée à stocker une énergie fournie, pendant une phase de charge, par une source de tension continue (30) à deux bornes d'alimentation du générateur (10), et transférer ladite énergie au dispositif à décharge à barrière diélectrique (20) pendant une phase de décharge par l'intermédiaire d'un transformateur (Ts), le générateur (10) comprenant en outre: - un agencement en série d'un premier (40) et d'un second (50) circuits connectés en un nœud N du générateur (10), - le premier circuit (40) comprenant deux branches (41, 42), l'une des deux branches (41) comprenant l'inductance (Lstock), et l'autre branche (42) comprenant une diode (D1) et le transformateur (Ts), le circuit secondaire (Ts2) étant connecté au dispositif à décharge à barrière diélectrique (20), - le second circuit (50) comprenant un interrupteur commandé (T1).
