Inductive energy storage properties

What is the rate of energy storage in a Magnetic Inductor?

Thus, the power delivered to the inductor p = v *i is also zero, which means that the rate of energy storage is zero as well. Therefore, the energy is only stored inside the inductor before its current reaches its maximum steady-state value, Im. After the current becomes constant, the energy within the magnetic becomes constant as well.

How is the energy stored in an inductor calculated?

The energy stored in the magnetic field of an inductor can be written as E = 0.5 * L * I^2, where L is the inductance and I is the current flowing through the inductor.

How does an inductor store energy?

An inductor stores energy in its magnetic field. As the current through the inductor increases, it forces the magnetic lines of force to expand against their natural tendency to shorten. This expansion stores energy in the magnetic field, similar to how a rubber band stores energy when stretched.

What are some common hazards related to the energy stored in inductors?

Some common hazards related to the energy stored in inductors are as follows: When an inductive circuit is completed, the inductor begins storing energy in its magnetic fields. When the same circuit is broken, the energy in the magnetic field is quickly reconverted into electrical energy.

How does Linear Technology affect inductor energy storage?

While one inductor’s current is increasing, the other’s is decreasing. There is also a significant reduction in the required inductor energy storage (approximately 75%). The inductor’s volume, and therefore cost, are reduced as well. See Linear Technology’s Application Note 77 for complete details.

When does the energy stored by an inductor stop increasing?

The energy stored by the inductor increases only while the current is building up to its steady-state value. When the current in a practical inductor reaches its steady-state value of Im = E/R, the magnetic field ceases to expand.
