ABSTRACT:
An automotive ignition system including an ignition capacitor electrically connected to a primary winding of a ignition transformer for providing energy to a spark plug which is connected to a second winding of the ignition transformer is disclosed. A charge circuit charges the ignition capacitor from a DC-DC voltage converter and includes an inductor and a thyristor. A discharge circuit discharges the ignition capacitor to the primary winding, and a control circuit operates the charge circuit and the discharge circuit in proper timed sequence during a demanded firing duration.
