Abstract
An ignition apparatus includes a high resistivity ferrite central core with a secondary winding disposed directly thereon. The ignition apparatus also includes, in a progressively coaxial fashion, a primary spool, a primary winding disposed on the spool, a case, and an outer core or shield of magnetically permeable material. The ignition apparatus exhibits reduced capacitance, and eliminates radial partial discharge at the inside diameter of the secondary winding.
