<p>The invention relates to a plasma-generating device comprising a plasma-generating spark plug containing a capacitive inductive resonator (RS2) that can produce a high voltage, generating means (MGN) designed to deliver successive trains of command pulses at a control frequency, and a voltage generator (GENI) comprising a commutation transistor (M1) having a command electrode connected to the outlet of the generating means and an outlet that can deliver a train of voltage pulses to the resonator in response to the train of command pulses received on the command electrode of the commutation transistor at a frequency equal to the resonance frequency of the resonator. On the end part (PFi) of each train (TRi), the generating means are designed to deliver the command pulses at a control frequency different from the resonance frequency of the resonator.</p> |
