Abstract
An ignition coil includes a first winding, a second winding, and a third winding. A first switch is electrically connected to the first winding. A battery is electrically connected to the first winding. A booster is electrically connected to the battery. A second switch is electrically connected to the third winding. A drive device drives the first switch and the second switch. The drive device turns the first switch from on-state to off-state to allow a secondary current to flow through the second winding, turns the second switch from off-state to on-state to supply an output of the booster to the third winding, and superimpose a second current to the second winding. When a third winding current becomes equal to or greater than a predetermined value, the booster controls such that power generated by the third winding current and an output voltage of the booster is restricted to constant power.
