Basics of Inductors PREPARED BY Rajani zaigam 236490316159
What is an Inductor? An inductor is a passive component that is used in most power electronic circuits to store energy in the form of magnetic energy when electricity is applied to it. It is also determined by several factors, such as The shape of the coil The number of turns and layers of the wire The space that is given between the turns. The size of core
Types of Inductors There are mainly two types of inductors Fixed inductors Variable inductors
Types of variable inductors There are mainly two types of variable Inductors Slug type Inductor Tapped variable Inductor
Slug typed Inductors It is probably used in bandpass filters in the intermediate frequency (IF) section of radio receivers to filter out interference from radio stations near in frequency to the desired station.
Tapped variable inductors A tapped variable inductor is a coil to which electrical contact is accessible at more points. This inductor mainly includes a coil with a huge number of turns. These turns are wounded on a magnetic core with a preferred number of tappings.
Types of fixed inductors Air core inductors Ferrite core Inductors Iron core Inductors
Air core inductors An inductors that use air as its core in the place of ferromagnetic materials
Ferrite core inductor The fixed value inductors which have a ferrite placed inside the coil
Iron core inductors In the areas where low space inductors are in need then these iron core inductors are best option These are applicable in audio equipments
Factors In which inductors depends There are mainly four factors which depends on the capacity of inductors. Inductance increases with the increase in the number of coils and vice-versa Inductance increases with more area in the cross-section of coils and vice-versa Inductance increases with the overlapping or narrowing of coils and vice-versa Inductance depends on the material that the coils are wrapped around
Construction of inductors An inductors is usually made from a coil of conducting material,that is wrapped around a core The use of more magnetic materials as the core gives better inductance Small inductors can also be put onto integrated circuits using the same ways that are used to make transistors Aluminum is usually used as the conducting material in this case
