Abstract (en)
[origin: EP0674102A2] The ignition system has at least one ignition end stage (Z) with an ignition coil (Tr), having primary and secondary windings, a transistor (T), in series with the primary winding and a capacitor (C) forming an oscillation circuit with the primary winding. An energy recovery diode (D) is connected across the transistor, with the current through the diode acting as the trigger signal for switching in the transistor. Pref. the current through the diode is detected by a series resistance (R2), with a clamping circuit (2) limiting the voltage for the switching transistor, provided by a voltage divider and a comparator, with its output coupled to the transistor control electrode.
