Why is it required to put an external inductor and diode at the
The inductor and diode are integral parts of a buck converter (this type of regulator). Without them, you cannot make a buck converter. In fact, most switching regulators need an inductor in them (charge pumps are the exception). You seem to be asking why you need your own diode and inductor, and why they aren''t just part of the regulator chip.

Solar energy needs reliable storage, and lithium-ion batteries store excess energy for later use. Here''s how to choose the best
Why use batteries instead of inductors to smooth out power
To do this, we need to store excess power when production is higher than demand, and hold it as long as we need to, until we release that power to make up the deficit when demand is higher than production. An inductor''s energy storage is depleted in one half a cycle, or one one hundred twentieth of a second. We do use large reactors

6 FAQs about [Why do we need energy storage inductors ]
What are inductors used for?
Inductors are crucial components in electrical systems, serving to store energy within a magnetic field when current flows through them. These components are common in electronic circuits, power supplies, and applications that require filtering, energy storage, or impedance control.
What is a DC inductor used for?
Inductors are typically used as energy storage devices in switched-mode power devices to produce DC current. The inductor, which stores energy, supplies energy to the circuit to maintain current flow during “off” switching periods, thus enabling topographies where output voltage exceeds input voltage.
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 does a solar energy storage inductor work?
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.
Does an inductor take more energy?
Thus, the inductor takes no more energy, albeit its internal resistance does cause some losses as the current flows through it, such that Plosses= Im2R. These losses are unavoidable because the constant current flow is necessary to maintain the magnetic fields.
Why do you need an inductor in an electrical circuit?
In such cases, an inductor can be added to limit the inrush current. Here, the inductors slow down current surges or spikes caused by the inrush current while still allowing the delivery of the inrush current to required applications. An inductor in an electrical circuit can have undesirable consequences if no safety considerations are implemented.
