Working Principle of Inductor
An inductor is a passive electronic component that can store electrical energy in the form of magnetic flux. It is usually in the form of a coiled wire. When current passes through it, a magnetic field is generated from the right side of the current flow direction.
When alternating current passes through the inductor, the magnetic field generated by the current cuts off the other windings, thus generating a reverse voltage, thereby hindering the current change. Conversely, when the current decreases, it is generated in the direction of increasing current.
If the direction of the current is reversed, a reverse voltage will also be generated. Before the current is blocked by the reverse voltage, the direction of the current will be reversed, so the current cannot flow. Therefore, an inductor is a component that allows direct current to pass, but not alternating current.
Classification of Inductors
There are many kinds of inductors, and various inductor products have appeared on the market, such as inductors for high-frequency circuits, power inductors, and inductors for general circuits. Today, I will focus on explaining power inductors, also known as power inductors.
