ABSTRACT:
In a non contact ignition circuit for an internal combustion engine, a current induced in the primary winding of an ignition coil is controlled and cut-off by operation, on and off, of a thyristor so as to produce a discharge in a spark plug. A capacitor connected to the gate of the thyristor is charged with an inverse voltage. When the rotational speed of the internal combustion engine exceeds a predetermined level, i.e. a state of overrotation, the inverse voltage stored in the capacitor is discharged whereby the gate potential of the thyristor is negatively biased relative to the cathode. Accordingly, during the discharging period of the capacitor, the triggering time of the thyristor and sparking are retarded as compared to the normal running condition of the internal combustion engine. Thereby overrotation of the internal combustion engine is prevented.
