Stand-alone switched-mode power supply An adjustable switched-mode power supply for laboratory use. A switched-mode power supply (SMPS), also called switching-mode power supply, switch-mode power supply, switched power supply, or simply switcher, is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently.
If the SMPS uses an adequately insulated high-frequency transformer, the output will be electrically isolated from the mains; this feature is often essential for safety. Switched-mode power supplies are usually regulated, and to keep the output voltage constant, the power supply employs a feedback controller that monitors current drawn by the load.
For high efficiency, the switched-mode power supply (SMPS) switch must turn on and off quickly and have low losses. The advent of a commercial semiconductor switch in the 1950s represented a major milestone that made SMPSs such as the boost converter possible. The major DC to DC converters were developed in the early 1960s when semiconductor ...
Shape-memory polymers (SMPs) are polymeric smart materials that have the ability to return from a deformed state (temporary shape) to their original (permanent) shape when induced by an external stimulus (trigger), such as temperature change.
SMPS may refer to: Scanning mobility particle sizer, an analytical instrument for aerosol particles; Switched-mode power supply, a type of electronic power supply;
Chopper circuits are used in multiple applications, including: Switched mode power supplies, including DC to DC converters.; Speed controllers for DC motors; Driving brushless DC torque motors or stepper motors in actuators

A scanning mobility particle sizer (SMPS) is an analytical instrument that measures the size and number concentration of aerosol particles with diameters from 2.5 nm to 1000 nm. [1] They employ a continuous, fast-scanning technique to provide high-resolution measurements.
