An electronic breakerless ignition system for an internal combustion engine. The ignition system comprises an alternating current generator synchronized with the engine. A rectifier circuit charges a storage capacitor. The storage capacitor is in series with a thyristor and the output of the ignition system, for example, a high tension ignition coil. The thyristor is triggered to discharge the storage capacitor by a voltage sensitive trigger circuit. One end of the trigger circuit is connected to the trigger terminal of the thyristor and the other end to one terminal of the generator.
