This invention is directed to a device for energy storage and transformation that allows an increased level of energy storable in an ignition coil, using a coil that has a permanent magnet inside of a primary magnetic core, with a second magnetic core that closes the magnetic path of the primary magnetic core.

Ignition coil with energy storage and transformation

An ignition coil configured for electrical communication with a spark plug of an internal combustion engine has a primary spool and a secondary spool. The primary spool has a bore and an outer surface with a low-voltage winding supported thereon. The secondary spool has a cavity with a magnetic core received therein and a substantially cylindrical outer surface. The secondary spool is received at least partially in the bore of the primary spool. A high-voltage winding is supported on the outer surface of the secondary spool. The high-voltage winding has discrete winding sectors spaced from one another along a length of the secondary spool.
