The energy stored in the inductor is proportional to the square of the current through it:

How does a switching power supply work?

In switching power supplies, the energy stored in capacitors and inductors is managed by a high frequency power switch. Switching power supplies operate at high frequency and the capacitors and inductors are therefore small.

How does a power supply store energy?

In order to function properly, power supplies need components to store and deliver energy. There are two types of energy storage devices used in power supplies: capacitors and inductors. Unlike resistors, ideal inductors and capacitors only store energy, but never dissipate energy.

How does a solar energy storage inductor work?

In this topology, the energy storage inductor is charged from two different directions which generates output AC current . This topology with two additional switching devices compared to topologies with four switching devices makes the grounding of both the grid and PV modules. Fig. 12.

Do linear power supplies use power inductors?

The purpose of the output capacitor is to provide control loop stability and holdup energy storage in the event of a momentary loss of input power. Linear power supplies must filter out line frequency noise, and the capacitors and inductors are therefore large. Linear supplies typically do not use power inductors in most applications.

What happens when an excited inductor loses connection to the supply?

When an excited inductor loses connection to the supply, it quickly breaks its magnetic fields and tries to continue the connection to the supply with the converted energy. This energy can cause destructive arcing around the point where the connection is lost. Thus, the connectivity of the circuit must be continuously observed.
