Abstract
A first series circuit having an energy storage coil 21, a first diode 3, and a capacitor 6 connected between a direct current power supply E and a ground terminal GND is arranged. A second series circuit of a switching element 5 and an ignition coil 4 is connected to both ends of the capacitor 6. The switching element 5 of the ignition device configured as above is controlled so as to perform a plurality of ON/OFF operations in time of the ignition operation of the ignition plug 8 connected to the secondary side of the ignition coil 4. As a result, the capacitive discharge and the inductive discharge are alternately repeated at the ignition plug 8. According to the present invention, a multiple discharge type ignition device in which the number of components is reduced, and the power consumption is suppressed is realized.
