Working principle :
After the primary coil is energized, a strong magnetic field will be generated around it with the increasing current. The iron core stores the energy of this magnetic field. When the primary coil circuit is broken by a switching gear, the magnetic field of the primary coil will attenuate quickly, inducing a very high voltage in the secondary coil. A shorter magnetic field disappearance time of the primary coil, a larger instantaneous breaking current, and a higher turn ratio all lead to a higher induced voltage in the secondary coil. The conversion from a low voltage to a high voltage is thus achieved. Like a regular transformer, the high turn ratio between primary and secondary coils enables such conversion on a car. The difference is that the ignition coil works in an intermittent way by storing and releasing energy cyclically at varied frequencies depending on changing engine RPMs.
Structure characteristics :
An ignition coil device is typically comprised of two coils: primary and secondary. The primary coil is often wound with an enameled wire 0.5-1 mm in diameter consisting of 200-500 turns, while the secondary coil is often wound with an enameled wire 0.1 mm in diameter consisting of 15000-25000 turns. The primary coil is connected to the positive pole of the onboard power supply at one end, and to a switching device (circuit breaker) at the other end. The secondary coil is connected to the primary coil at one end, and to the output of the high-voltage line at the other end to provide high-voltage output.
