Abstract: An ignition coil includes a magnetically-permeable core, a primary winding disposed outward of the core, and a secondary winding disposed outward of the primary winding and inductively coupled to the primary winding. The secondary winding includes a left secondary winding section wound clockwise around the primary winding and a right winding section wound counterclockwise around the primary winding. The left secondary winding section has i) a first left winding end distal from the right winding section and ii) a second left winding end that is proximal to the right winding section. The right secondary winding section has i) a first right winding end distal from the left winding section and ii) a second right winding end that is proximal to the left winding section. The second left winding end and the second right winding end are connected to a terminal.
