Abstract:
An ignition control device for an internal combustion engine can include an ignition coil supplying a discharge voltage to an ignition device of an ignition combustion engine, a voltage-controlled type semiconductor element connected to a primary side of the ignition coil and an ignition control section capable of repeating, multiple time in an ignition period, operations of turning ON and turning OFF of the voltage-controlled type semiconductor element by giving a gate signal to a gate of the voltage-controlled type semiconductor element. The ignition control section can include an active element that discharges gate charges accumulated on the gate of the voltage-controlled type semiconductor element upon turning OFF operation of the voltage-controlled type semiconductor element to the ground, and that is connected between the gate and a resistor at a side of the gate inserted in a gate wiring connected to the gate of the voltage-controlled type semiconductor element.
