Automobile ignition coil

Give you a brief introduction of the working principle of automobile ignition coil. Automobile ignition coil can will become high voltage low voltage electric car, is due to have the same form with ordinary transformer, the number of turns of the primary coil and secondary coil. But works on the ignition coil is different from the ordinary transformer, general transformer is a continuous work, while the ignition coil is intermittent, it according to the different rotating speed of the engine at a different frequency for energy storage and put over and over again. When the primary coil processing power, as the growth of the current around to create a strong magnetic field, an alternating magnetic field to store the can; When the switch device makes the primary coil circuit disconnect, primary coil magnetic field decay quickly, secondary coil will be induced high voltage. The faster the primary coil of the magnetic field disappeared, disconnect instantaneous current, the greater the two coil turns ratio, the greater the secondary coil induction out the higher voltage.
