After the ignition coil core is saturated, how can the core be restored to the unsaturated state? The next chapter of Dongguan precision magnetic electronics technology is for you to answer:
1, after the ignition coil core is saturated, reducing the excitation current and excitation voltage can restore the core to an unsaturated state;
2, hysteresis: Magnetic materials have the tendency to retain their magnetism, and the change of B always lags behind the change of H. This phenomenon is called hysteresis;
In this material, the relationship between magnetic field strength(H) and magnetic induction strength(B) is non-linear. After the excitation power supply is cut off, the core retains the magnetic induction intensity of the direction and size at the last moment before the power is cut off;

　3, the saturation of the core of the ignition coil is temporarily saturated. When the excitation power supply is eliminated, the magnetic properties of the material are restored;
4, under the action of sine excitation power supply, when the excitation voltage or excitation current reaches the maximum, it will reach the threshold of iron core magnetic saturation. In most cases, the voltage current is under this threshold, and this time the iron core is No magnetic saturation, For normal magnetic induction.
The relevant analysis of how to restore the core of the ignition coil after it is saturated is introduced to you here. After you read the article, do you find that there is any improvement in the article? If you do, please make sure to contact us in time!
