ABSTRACT:
A high energy ignition generator includes an energy source connected to a circuit for charging an energy storage capacitor. The storage capacitor is connected to a discharge circuit consisting of a series inductive circuit for energy recovery and an ignitor having terminals to which are connected freewheel diodes. Sparks are generated between the electrodes of the ignitor, by the discharge of the capacitor in the igniter through the inductive circuit for energy recovery and by the discharge of the inductive circuit in the igniter through the freewheel diodes. The inductive circuit includes at least two inductors. The at least two inductors are connected in series with the capacitor at the time of its discharge and are connected in parallel with the terminals of the igniter at the time of their discharge.
