A coupled inductor has more than one winding wound on the magnetic core. It is typically used for energy storage [1,2] in many power electronic networks such as electric energy storage systems, electric vehicles, or photovoltaic systems [3,4]. The abovemen‐tioned systems require the use of various types of converters.

Inductors store energy in their magnetic field, making them useful in various applications, such as energy storage systems, DC-DC converters, and switching regulators. In these applications, inductors work in conjunction with other components, like capacitors and diodes, to store and release energy, helping to maintain a stable output voltage or current.

The reactance is inductive if it releases energy in the form of a magnetic field. And the reactance is capacitive if it releases energy in the form of an electric field. As frequency increases, capacitive reactance decreases, and inductive reactance increases. An ideal resistor has zero reactance, whereas ideal inductors and capacitors have ...

In its most basic form, an Inductor is nothing more than a coil of wire wound around a central core.
