Abstract
The present invention refers to an apparatus for raising the spark energy in capacitive ignition systems comprising at least one charge winding (L) which via a first rectifier device (D) charges a charge capacitor (C) connected to the primary winding of an 5 ignition voltage transformer in order to provide said primary winding with energy for generation of a spark characterized in that additionally a second rectifier device (D) and a switching device (Q) are arranged in such a way that the switching device periodically can short circuit the charge winding and thereby increase the charge of the charge capacitor at low engine speeds.
