Optimal Design of Copper Foil Inductors with High Energy Storage

When designing the structure of the energy storage inductor, it is necessary to select the characteristic structural parameters of the energy storage inductor, and its spiral structure is usually ignored when simplifying the calculation, that is, the n-turn coil can be equivalent to N closed toroidal coils. Taking copper foil inductors as an example, the two

Inductor

An inductor, also called a coil, choke, or reactor, is a passive two-terminal electrical component that stores energy in a magnetic field when electric current flows through it.
