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.
Energy in the inductor is stored in the form of a magnetic field. When current is applied, the energy of the magnetic field expands and increases the energy stored in the inductor. The energy remains constant as long as the current is maintained. If the current is removed, the energy is discharged as the magnetic field contracts.
Self-Induction: Self-induction is the phenomenon where a changing current in an inductor induces a voltage across itself due to its own magnetic field. Energy stored in an inductor is the electrical energy accumulated in the magnetic field created by the flow of current through the inductor.
Inductance of the coil: The amount of energy stored in an inductor is directly proportional to its inductance. Higher the inductance, higher will be the energy stored. Current flowing through the coil: The energy stored is directly proportional to the square of the current flowing through the inductor.
A. The initial energy stored in an inductor depends on the coil inductance, the current passing through the inductor, and the rate of change of this current. The presence of a magnetic core material can also increase the energy-storage capacity. B.
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.
