Abstract

PURPOSE:To prevent recirculation phenomenon and allow the stable electric discharge of an ignition plug to be continued by applying the noise voltage in the operating signals of a current-cut-off element to the control element for controlling the cut-off element. CONSTITUTION:The base resistance of a cut-off transistor 10 is divided into two parts 8A and 8B, and the collector of a controlling transistor 18 is connected between resistances 8A and 8B, and the emitter is grounded. The base of the controlling transistor 18 is connected with the output of an amplification circuit 6 through a condenser 17 and connected with the point which divides the power voltage through resistors 15 and 16, and a bias voltage is applied. The resistor 8A and the condenser 17 transmitts effectively only high frequency voltages such as noise voltage. The second turning-ON of the cut-off transistor 10 directly after the primary current of an ignition coil 13 is cut-off is removed.
