How to store energy to close the switch

How can electrical energy be stored?

To store electrical energy, you have to convert it into another form, such as chemical energy, like batteries, and turn it back into electricity when needed. Electrical energy is a constant flow of electrons that move within a conductor.

Why is the inductor used as a storage device in switching power supplies?

This is why it is used as one of the storage devices in switching power supplies; the capacitor maintains the same voltage, and the inductor maintains the same current. (But don't try to actually build this circuit.) @Andyaka: So it should.

How to reduce switching loss?

We would like tr, tf ↓ to reduce switching loss, but other factor come into play: 2. EMI 3. Rate limits 4. Safe operations area (SOA) Limit maybe instantaneous power, “second break- Some devices cannot sustain high simultaneous v,i. 3 4 24C We reduce device turn-of loss with the capacitor!

What happens when a power supply is removed?

When the supply is removed, the collapsing magnetic field induces a current flow in the same direction that it was traveling when it generated the magnetic field in the first place. This is why it is used as one of the storage devices in switching power supplies; the capacitor maintains the same voltage, and the inductor maintains the same current.
