6 FAQs about [Using inductive energy storage to supply power]

Why should you use an inductor for energy storage?

Because the current flowing through the inductor cannot change instantaneously, using an inductor for energy storage provides a steady output current from the power supply. In addition, the inductor acts as a current-ripple filter. Let’s consider a quick example of how an inductor stores energy in an SMPS.

Should a current supply contain an inductor as energy storage component?

It is quite obvious that one current supply containing an inductor as energy storage component will be a better choice, because the inductive current cannot leap immediately even though the loads are fluctuating. Meanwhile, the circuit systems may be exposed to the risk of overvoltage caused by the inductor.

How does an inductor store energy in an SMPS?

Let’s consider a quick example of how an inductor stores energy in an SMPS. Closing the switch for a switched mode power supply increases the current flowing to the load and allows energy to store in the inductor. Opening the switch disconnects the output of the supply from the input.

What factors affect the energy storage capacity of an inductor?

The energy storage capacity of an inductor is influenced by several factors. Primarily, the inductance is directly proportional to the energy stored; a higher inductance means a greater capacity for energy storage. The current is equally significant, with the energy stored increasing with the square of the current.

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 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.
