Abstract
A device for regulating the energy supply for the ignition of an internal combustion engine including an ignition coil and a central control unit, the ignition coil including a primary winding and an ignition power module connected to the primary winding. The central control unit ascertains a time difference between the beginning of current flow through the primary winding and the reaching of a first threshold value of the primary current, and in the light of the time difference, the central control unit determines an additional power loss of the ignition power module and/or active energy reduction, caused by interturn short circuits in the primary winding. When the additional power loss of the ignition power module exceeds a power loss threshold value, the ignition power module is switched off.
