SMPS stands for Switched-Mode Power Supply. It is a type of power supply that uses a switching regulator to convert electrical power efficiently. SMPS is used in electronic devices and equipment to convert AC power from a wall outlet into DC power that can be used by electronic circuits.

SMPS works by rapidly switching a power semiconductor on and off at high frequencies, typically between 50 kHz to several hundred kHz. This rapid switching allows for the efficient conversion of electrical power. SMPS typically have a higher efficiency than linear power supplies, which dissipate excess power as heat.

SMPS are used in a wide range of electronic devices, including computers, televisions, audio equipment, and medical equipment. They are also used in renewable energy systems, such as solar panels and wind turbines, to convert the DC power generated by these systems into AC power that can be used by the electrical grid.
