Abstract
An ignition apparatus includes a transformer having a central core, a primary winding disposed thereabout, a secondary winding disposed outwardly of the primary winding, a case configured to house the central components, and an outer core or shield disposed outwardly of the secondary winding. The central core is formed from multiple, low carbon steel wires held together is a cylindrical shape with cured bond coating material such as an epoxy material or an aromatic polyamide material. In one configuration, at least two different sizes of wires are used in forming the core to increase the density of the magnetically-permeable wire material in the core.
