There are three different types of ferrite core inductor available in the market. These include magnetic field, electromagnetic field and permanent magnetic field induction. The main advantage of using this induction is that it is safe and efficient for the end-user. With this type of induction, the electrical current passing through the coil is induced in a linear fashion with a very high frequency level. This means that the currents will be in a state that is similar to a very high frequency level.
The ferrite core inductor is essentially the permanent magnetic field induction that has a ferrite core inserted inside the primary coil. As the name suggests, the magnetic field induced through the ferrite core is very high. However, the inductions also have some drawbacks. The electromagnetic field inductor has a lower inductance values, limited frequency operation, low voltage operation, minimal losses and many other losses. On the other hand, the electromagnetic field induction usually produces higher output power with a very low maintenance and operating costs.
It is important to note that even though the inductor has a high level of inductance, the input capacitance level is often quite low as well. Therefore, the efficiency of the converter will often be quite low. For this reason, most of the ferrite core inductor designs are also used for boosting the input capacitance level of the devices in conjunction with a surge protector that is placed on the circuit's negative side.
The third type of ferrite core inductor that is used to power a number of different consumer electronic products is the bobbin indicator. The concept behind this type of induction is similar to the magnetic induction. It works by the flow of current through a winding, where it induces a magnetic field that creates a temporary voltage across the wire. The current induced through the winding can be reversed as the power is removed from the wire. In the majority of the designs for these types of indicators, the wire that is being induced will be insulated to avoid shorting. The resistance level needed will be determined by the current that will be induced through the wire.
The bobbin design is also combined with a secondary winding to provide a smoother operation. Unlike the previous design, the second magnetic field will not be induced into the wire. This provides smoother currents which in turn create a smooth magnetic field. Because of the smoother currents, the switching frequencies of the ferrite core inductor will be much lower than the other designs.
The three basic designs for ferrite core inductor are the air core, wire wound and the coil wound. The air core uses a copper coil that is placed inside a metallic casing while the wire wound uses an air gap between the metallic part and the coil to create a magnetic field. Both of the designs have their own advantages and disadvantages depending on the application and the type of materials to be used for the construction.
