The ability of an inductor to store energy in the form of a magnetic field (and consequently to oppose changes in current) is called inductance. It is measured in the unit of the Henry (H). Inductors used to be commonly known by another term: choke. In high-power applications, they are sometimes referred to as reactors.
The area of final recourse is mentioned by fraxinus - energy storage in stray or interwinding capacitance. Even an ideal inductor has capacitances associated with it and you will see 1/2.L.i^2 energy redistrubted into 1/2.C.V^2 energy.
Inductors and capacitors both store energy, but in different ways and with different properties. The inductor uses a magnetic field to store energy. When current flows through an inductor, a magnetic field builds up around it, and energy is stored in this field. The energy is released when the magnetic field collapses, inducing a voltage in the ...

If there is nothing in parallel with the switch branch, then the opening switch can interrupt the current only by absorbing all of the energy stored in the circuit inductance and recovering against the open circuit voltage of the current source. The severity of the switching problem depends upon the makeup of the rest of the circuit.

The purpose of an opening switch is simply to stop the flow of current in the circuit branch containing the switch and to accomplish current interruption, the opening switch must force the current to transfer from the switch to a parallel circuit branch and then withstand the voltage generated by the current flowing through the load. The purpose of an opening …
In its most basic form, an Inductor is nothing more than a coil of wire wound around a central core. For most coils the current, ( i ) flowing through the coil produces a magnetic flux, ( NΦ ) around it that is proportional to this flow …
Mathematically, energy stored in an inductor is expressed as. Where w is the energy stored in the inductor, L is the inductance and i is the current passing through the inductor. Ideal inductors have a noteworthy characteristic - they do not dissipate energy. This trait allows the energy stored within them to be harnessed at a later point in time.

Although the capacitive energy storage (CES) has been the dominating method so far, it has been long since people realized that inductive energy storage (IES) could be more efficient and compact [4]. The obstacle that has hampered IES has been the lack of suitable opening switches, because high-voltage, high-speed, and high-efficiency opening switch …

The magnetic field which stores the energy is a function of the current through the inductor: no current, no field, no energy. You''ll need an active circuit to keep that current flowing, once you cut the current the inductor will release the magnetic field''s energy also as a current, and the inductor becomes a current source (whereas its dual, …
A basic inductive energy discharge circuit is shown in Fig. 12, using capacitor C as primary electric energy storage and a LC resonant circuit, where two types of switches are used, normally open S 1 and S 3 and normally close S 2 2006).
When the current decreases, the magnetic field collapses, releasing the stored energy back into the circuit. Thus, the inductor acts as an energy storage device, temporarily holding energy in the form of a magnetic field. The energy stored in an inductor can be calculated using the following formula: E = 1/2 * L * I 2.

Inductor. The energy storage inductor in a buck regulator functions as both an energy conversion element and as an output ripple filter. This double duty often saves the cost of an additional output filter, but it complicates the process of finding a good compromise for the value of the inductor.
