Method for operating an ignition device for an internal combustion engine, and ignition device for an internal combustion engine for implementing the method.The present invention relates to a method for operating an ignition device for an internal combustion engine, the ignition device is formed with an ignition coil (ZS) that is configured as a transformer, a spark plug (zk) that is connected to the winding if Cundu00e1rio of the ignition coil (ZS),A switching element atuu00e1vel (IGBT) that is connected in series to the primary winding of the ignition coil (ZS), and a control unit (SE) which is connected to the control input of the switching element (IGBT).And the control unit (SE) provides a supply voltage adjustable (vsupply) for the ignition coil (ZS) and an actuation signal (IGBT control) for the switching element (IGBT) as a function of the currents (I _ prim.I _ sec) through the primary and secondary windings of the ignition coil (ZS) and the voltage between the connection point of the primary winding of the ignition coil (ZS) for the switching element (IGBT) and to the negative terminal of the supply voltage (GND), as a result of the That, first, the operation of the spark plug (zk) by means of an alternating current becomes possible.Secondly, regulation D ITA current becomes possible, resulting in a more reliable ignition, with a lower wear of spark plugs.
