ABSTRACT:
An a.c. ignition system for an engine, with an ignition transistor that switches the primary winding of an ignition coil, with a control circuit for controlling the ignition transistor and a parallel circuit including a capacitor and a diode between the emitter and collector of the ignition transistor. The control circuit can receive a measuring signal that is proportional to the collector potential of the ignition transistor, and the control circuit controls the ignition transistor depending on the measuring signal so that the ignition transistor is activated at a low voltage between the collector and emitter of the transistor.
