An inductor or choke is a passive electrical component that stores energy in a magnetic field when electric current flows through it, used for filtering, energy storage, and impedance matching in power supply regulation circuits.
An inductor, also known as a choke, is a two-terminal passive electronic component consisting of a coil of insulated wire wound around a magnetic core or air core. It opposes changes in current flow due to its property of inductance, measured in henries (H). In power supply regulation systems, inductors are critical for smoothing DC output by filtering out AC ripple, storing energy during switching cycles, and providing impedance to suppress electromagnetic interference (EMI). They function as energy storage devices in switch-mode power supplies (SMPS), buck/boost converters, and LC filters to maintain stable voltage and current levels.

An inductor is a general term for the component, while a choke specifically refers to inductors designed to block (choke) high-frequency AC signals while allowing DC or low-frequency signals to pass, commonly used in power supply filters.
Inductors store energy during switching cycles in converters like buck or boost topologies, reducing power loss by smoothing current flow and minimizing ripple, which enhances overall efficiency and stability.
Saturation occurs when the magnetic core can no longer store additional energy, causing a sharp drop in inductance. It is prevented by selecting cores with higher saturation flux density, using air gaps, or oversizing inductors for the application's current requirements.
