Modelling an induction coil with fractional-order magnetic coupling in an ignition system of internal combustion engines

The test subject is an ignition system modelled by a set of two induction coils with an open ferromagnetic core that constitutes an ignition coil. The essence of the tests is the application of magnetic coupling of the fractional order that enables taking into account the non-idealities of the coils and the connector that implements the ignition point. The paper contains the results of a theoretical analysis, supported by digital simulations.
