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.
SMPS may refer to: Scanning mobility particle sizer, an analytical instrument for aerosol particles; Switched-mode power supply, a type of electronic power supply;
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.

A power supply with a 24-pin connector can be used on a motherboard with a 20-pin connector. In cases where the motherboard has a 24-pin connector, some power supplies come with two connectors (one with 20-pin and other with 4-pin, i.e. 20+4-pin form) which can be used together to form the 24-pin connector.

In the example of the dent, the fender could be repaired with a heat source, such as a hair-dryer. The impact results in a temporary form, which changes back to the original form upon heating—in effect, the plastic repairs itself. SMPs may also be useful in the production of aircraft which would morph during flight.
Classic solutions such as passive filters reduce THD I to 5%–10% at full load. They are reliable, but big and only work at full load, and present their own problems when used in tandem with generators. An alternative solution is an active filter. Through the use of such a device, THD I can drop to 5% over the full power range. The newest ...
