Ignition system with an ignition coil that is supplied on the primary side by a high frequency source (HF source), wherein the voltage output by the HF source is pulse width modulated and a means (6) for picking up the secondary side current (actual value) is provided, wherein a regulating means (8) is provided that regulates the pulse width dependent upon the measured actual value of the current on the secondary side of the ignition coil and upon a pre-selected reference value development of the current amplitude during an ignition spark.
