Abstract
An ignition system is for an internal combustion engine having an ignition device that requires a high voltage (ignition voltage) for igniting the ignition spark. Two ignition coils are provided, which have secondary windings that are each connected to electrodes of a spark plug, which have primary windings that may be connected in each case by a switching arrangement to a supply voltage source, and a drive circuit, via which the ignition coils are driven in a time-displaced manner.
