Inductors are used as the energy storage device in many switched-mode power supplies to produce DC current. The inductor supplies energy to the circuit to keep current flowing during the "off" switching periods and enables topographies where the output voltage is higher than the input voltage.

HIGH FREQUENCY MODEL OF COUPLED INDUCTORS. In this study, a prototype of the coupling inductors has been realized with EPCOS ferrite material N30 [12]. The core shape is a ring R58.3/40.8/17.6 and each winding is made of 15 turns of copper (diameter 1.5mm).
Although the two may seem interchangeable, there are several distinctions between them. Inductors can generate magnetic fields and can also store energy within magnetic fields. A choke''s primary purpose is to remove
They can also be used as a 2-in-1 solution for multiphase topologies. Coupled inductors help significantly reduce the board´s complexity and improve the circuit''s efficiency. TDK''s coupled inductors are available in four footprints from 7 x 7 mm to 12 x 12 mm and have an inductance range from 2 µH to 100 µH.

Basic Structure of Inductors and Inductance. The most basic inductors consist of a conductive wire wound in a coil shape, with both ends of the conductive wire as external terminals. In recent years, most inductors include a core, around which a conductive wire is wound. The inductance of an inductor is determined by the following
An inductor placed in series (in line) with a conductor, such as a wire or circuit board trace, blocks or impedes changes in current and functions as a low pass filter. Because inductors restrict or choke changes in current, they are also called "chokes". For example, a broadband (wideband) bias choke in line with the DC bias of an amplifier
