Abstract
An ignition coil includes a first winding, a second winding, and a third winding. A first switch is electronically connected to a first end of the first winding. A battery is electronically connected to a second end of the first winding. A booster with a first end electronically connected to the battery and a second end electronically connected to a first end of the third winding. A second switch is electronically connected to a second end of the third winding. A drive device is electrically connected to the first and the second switches, that turns the first 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 third winding by changing the second switch from an off-state to an on-state.
