  • Publication number: 20190277214
    Abstract: A system and/or method for a boosted non-linear coil includes an ignition coil including a first primary winding, a second primary winding and a secondary winding. A control circuit connects with the ignition coil, the control circuit including a logic device, a first switch connected with the logic device and the first primary winding and a second switch connected with the logic device and the second primary winding. The logic device controls a determined time for switching the first switch and for switching the second switch.

  • Patent number: 9816476
    Abstract: An ignition coil system is configured for use with a spark ignition internal combustion engine. The system includes a first switching circuit electrically connected to the primary coil that provides electrical power to the primary coil. The system includes a second switching circuit connected to the primary coil that is configured to short the terminals of the primary coil after the secondary current has been induced in the secondary coil, whereby the secondary coil induces a current in the primary coil, thereby reducing the secondary current in the secondary wire coil. A controller in communication with the first and second switching circuits is configured to receive a single electronic spark timing (EST) signal and to control the conductive states and the non-conductive states of the first and second switching circuits based on this single EST signal.
