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.
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.
Inductors are used as the energy storage device in many switched-mode power supplies to produce DC current. The inductor supplies energy to the circuit to keep current flowing during the "off" switching periods and enables topographies where the output voltage is higher than the input voltage.
In this topology, the energy storage inductor is charged from two different directions which generates output AC current . This topology with two additional switching devices compared to topologies with four switching devices makes the grounding of both the grid and PV modules. Fig. 12.
