Ignition coil theory
There are usually two groups of coils in the ignition coil, the primary coil and the secondary coil. The primary coil is made of thick enamelled wire, usually about 200-500 turns of enamelled wire of about 0.5-1mm; The secondary coil is wound with fine enamelled wire, usually about 15000-25000 turns with enamelled wire of about 0.1mm. One end of the primary coil is connected with the low-voltage power supply (+) on the vehicle, and the other end is connected with the switching device (circuit breaker). One end of the secondary coil is connected with the primary coil, and the other end is connected with the output end of the high-voltage line to output high-voltage power.
The reason why the ignition coil can change the low-voltage power on the vehicle into high voltage is that it has the same form as the ordinary transformer. The primary coil has a larger turn ratio than the secondary coil. However, the working mode of the ignition coil is different from the ordinary transformer. The working frequency of the ordinary transformer is fixed 50Hz, also known as power frequency transformer, while the ignition coil works in the form of pulse, which can be regarded as pulse The impulse transformer repeatedly stores and discharges energy at different frequencies according to different engine speeds.
When the primary coil is connected to the power supply, a strong magnetic field is generated around with the increase of current, and the magnetic energy is stored in the iron core; when the switching device disconnects the primary coil circuit, the magnetic field of the primary coil decays rapidly, and the secondary coil will induce a high voltage. The faster the magnetic field of the primary coil disappears, the greater the current at the moment of current disconnection, and the higher the turn ratio of the two coils Large, the higher the voltage induced by the secondary coil.
