Abstract
An ignition apparatus includes a suppression device comprising a suppression winding that is in series with the secondary winding and is further located outside of a magnetic circuit. The suppression winding is made from the same wire as used in the secondary winding and is wound on a reduced diameter portion of a secondary winding spool. A carbon resistor is disposed in series with the suppression winding in another embodiment. Nickel wire may be substituted for the suppression winding and carbon resistor in order to obtain both inductance and resistance characteristics for the suppression device.
