Abstract
A method is disclosed for operating an ignition device for an internal combustion engine, said device having an ignition coil designed as a transformer, an igniter plug connected to the ignition coil secondary winding, a controllable switching element connected in series to the ignition coil primary winding and a control unit connected to the ignition coil primary winding and the control input of the switching element, wherein the control unit provides a supply voltage for the ignition coil and a control signal for the switching element depending upon the flows through the ignition coil primary and secondary winding and the voltage between the connection point of the ignition coil primary winding to the switching element and the negative terminal of the supply voltage, to provide an adjustable alternating current for the igniter plug, to provide a targeted supply of power distributed over the ignition time interval.
