Abstract
An embodiment of an ignition device comprises an ignition coil including a first winding and a second winding electromagnetically coupled to each other, a first switch electrically connected to a first end of the first winding, a battery electrically connected to a second end of the first winding, a booster with a first end electrically connected to the battery, a second switch electrically connected to a second end of the booster and to the second end of the first winding, and a drive device electrically connected to the first switch, that turns the first switch and the second switch on and off. The drive device feeds a secondary current to the second winding by changing the first switch from an on-state to an off-state, and supplies an output from the booster to the first winding by changing the second switch from an off-state to an on-state.
