6 FAQs about [The energy storage inductance is too small]

How does inductor size affect energy storage?

Different core materials can store different amounts of magnetic energy per volume, but within the same core material, inductor size is largely dictated by energy storage. The energy a inductor can store, in common units, is: J = ½ A 2 H where J is the energy in Joules, A the current thru the inductor in Amps, and H the inductance in Henrys.

How much energy can a inductor store in common units?

The energy a inductor can store, in common units, is: J = ½ A 2 H where J is the energy in Joules, A the current thru the inductor in Amps, and H the inductance in Henrys. Look at a family of inductors that all use the same core, and you will see that the maximum energy storage is about the same across the family.

How do you find the energy stored in an inductor?

The energy, stored within this magnetic field, is released back into the circuit when the current ceases. The energy stored in an inductor can be quantified by the formula \ ( W = \frac {1} {2} L I^ {2} \), where \ ( W \) is the energy in joules, \ ( L \) is the inductance in henries, and \ ( I \) is the current in amperes.

How do inductors store energy?

In conclusion, inductors store energy in their magnetic fields, with the amount of energy dependent on the inductance and the square of the current flowing through them. The formula \ ( W = \frac {1} {2} L I^ {2} \) encapsulates this dependency, highlighting the substantial influence of current on energy storage.

The inductance (\ ( L \)) of an inductor, a measure of its ability to store energy in a magnetic field, is a fundamental property that determines how much opposition the inductor presents to changes in current, thus affecting the induced voltage.

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.
