Abstract
An ignition device for igniting an air-fuel mixture in a combustion chamber, in particular an internal combustion engine, having a spark plug, which has a first electrode and a second electrode, and a high voltage source for generating an electrical high voltage pulse at an output of the high voltage source and having a high frequency voltage source for generating an electrical high frequency alternating voltage at an output of the high frequency voltage source, wherein the output of the high voltage source is electrically connected to the first electrode of the spark plug via a first electrical conductor path such that the high voltage pulse is applied to the first electrode, wherein the second electrode is electrically connected to an electrical ground potential, wherein the spark plug has a third electrode, wherein the output of the high frequency voltage source is electrically connected to the third electrode via a second electrical conductor path, such that the high frequency alternating voltage is applied to the third electrode.
