How does the switching power supply energy storage inductor store energy

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. At this point, drawing energy from the inductor maintains a stable output current.

FAQS about How does the switching power supply energy storage inductor store energy

How does an inductor store energy?

Inductors Store Energy The magnetic field that surrounds an inductor stores energy as current flows through the field. If we slowly decrease the amount of current, the magnetic field begins to collapse and releases the energy and the inductor becomes a current source.

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.

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.

How does a switched mode power supply work?

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. At this point, drawing energy from the inductor maintains a stable output current.

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.

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.
