Abstract: An ignition coil for delivering a spark-generating current to a spark plug includes a magnetically-permeable core; a primary winding disposed outward of the core; and a secondary winding radially surrounding the primary winding and inductively coupled to the primary winding, the secondary winding having a low-voltage end and a high-voltage end. The secondary winding includes a secondary winding first section proximal to the low-voltage end and having a first thickness. The secondary winding also includes a secondary winding second section proximal to the high-voltage end and having a second thickness that is less than the first thickness of the secondary winding first section.
