The invention relates to a resonance inverter comprising a resonance circuit with at least one inductance and one capacitor, a switch circuit electrically connected to the resonance circuit and comprising at least one power electronic component, as well as a control circuit for controlling each power electronic component in accordance with a given control algorithm or strategy, said control circuit being electrically connected to the switch circuit. The unique feature of the invention is that the resonance inverter additionally comprises a pulse generating circuit (12'; 15; 32', 31) having at least one control inductance (12', 32') which is inductively coupled to at least one of the inductances (12; 32) of the resonance circuit, whereby energy is transferred inductively to the resonance circuit.

L'invention concerne un inverseur de résonance comprenant un circuit de résonance, un circuit de commutation relié par couplage électrique au circuit de résonance et doté d'au moins un composant électronique de puissance, ainsi qu'un circuit de commande permettant de commander chaque composant électronique de puissance selon un algorithme ou une stratégie de commande donnés. Ce circuit de commande est relié au circuit de commutation par couplage électrique. L'invention est caractérisée en ce que le convertisseur de résonance comprend, en plus, un circuit générateur d'impulsions (12'; 15; 32', 31) possédant au moins une inductance (12', 32') qui est reliée par couplage inductif à au moins une des inductances (12; 32) du circuit de résonance, l'énergie étant transférée par induction au circuit de résonance.
