Abstract
An ignition system and a method for controlling an ignition system for a spark-ignited internal combustion engine are described, having a primary voltage generator for generating an ignition spark and a boost converter for maintaining an ignition spark. The method includes sending a signal from an engine control unit to the ignition system, in order to determine a predetermined ignition timing for triggering an ignition spark, sending an additional signal from the engine control unit to the ignition system, in order to determine a predetermined additional ignition timing for triggering an additional ignition spark, and sending a control signal for influencing the operating mode of the boost converter from the engine control unit to the ignition system between the signal and the additional signal.
