Abstract

PURPOSE:To adapt to change a signal genetating source to a more inexpensive signal generator to genearate square wave signals and to ensure efficient control of closing angle without using an AC generator. CONSTITUTION:The output of a signal generator 10 to generate square wave signal synchronized to the number of engine revolutions by the use of a Hall element and the like is input into a comparison circuit 200 through a wave-form computing circuit 100 for comparing the output of computed wave-form in the circuit 100 with a certain reference voltage. The output of the circuit 200 is sent to a drive circuit 300, whose output is used to control the base current of the last stage power transistor 5. The primary current in an ignition coil 4 is detected, and a current limiting circuit 400 to give fixed value constant-current control to the primary current is connected to the above-written transistor 5. To this circuit 400, a feedback circuit 500 is connected for generating the output to compensate the start timing to give the primary current to the ignition coil 4 according to the time of the constant- current control.
