Abstract
An ignition system for an internal combustion engine having an AC generator comprises an ignition coil energized by an AC output from the generator. A first thyristor is connected in series with the primary of the ignition coil and permits and interrupts the current through the primary. The first thyristor is turned on at a first angle in advance of ignition. A capacitor is charged by an AC output from the generator, and is discharged when a second thyristor conducts to apply a reverse voltage across the anode and cathode of the first thyristor. The second thyristor is triggered at a second angle.
