Abstract
In an alternating current ignition system whose ignition output stage has an ignition coil, a resonant-circuit capacitor for generating a bipolar alternating current, a semiconductor switch for controlling the primary coil current and an energy recovery diode connected in parallel to the semiconductor switch, the current flowing through the diode serves as control signal for the semiconductor switch and triggers the switching-on of the semiconductor switch.
