Filed:

Jul 13, 2018

Appl. No.:

16/630810

Inventors:

- Farmington Hills MI, US
ALBERT ANTHONY SKINNER - WATERFORD MI, US
DAVID LESTER LANGLEY - BRIGHTON MI, US
PAUL BRYAN DEIGNAN - LAFAYETTE IN, US

International Classification:

H01F 27/28
H01F 27/08
H01F 27/24

Abstract:

In an example, a transformer can include a core that can include a composite material and have a first permeability. The transformer can further include a primary coil that can be wound about the core. The primary coil can be configured to vary a primary magnetic energy into the core based on a primary current. The transformer can include a secondary coil that can be wound about the core. The secondary coil can be configured to establish a secondary voltage based on the primary magnetic energy. The transformer can further include an outer return that can include a laminate material and have a second permeability. The second permeability can be greater than the first permeability. The outer return can provide a magnetic-return path for magnetic energy from a first end of the core to a second end of the core.

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.
