ABSTRACT:
A spark ignition system utilizes a one transistor inverter including a transformer with a primary winding, controlled by the transistor and a feedback winding switching the transistor on and off. The core of the transformer saturates at a current less than that required to saturate the transistor. An inductor in series with the primary winding has an inductance greater than that of the primary winding when the latter is saturated but less than that of the primary winding when the latter is not saturated. The second winding is used to charge a capacitor which has a spark circuit across it.
