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. Like other power supplies, an SMPS transfers power from a DC or AC source (often mains ...
A silicon controlled rectifier or semiconductor controlled rectifier is a four-layer solid-state current -controlling device. The name "silicon controlled rectifier" is General Electric 's trade name for a type of thyristor. The principle of four-layer p–n–p–n switching was developed by Moll, Tanenbaum, Goldey, and Holonyak of Bell ...
Ring-based: The power gates are placed around the perimeter of the module that is being switched off as a ring. Special corner cells are used to turn the power signals around the corners. Column-based: The power gates are inserted within the module with the cells abutted to each other in the form of columns. The global power is the higher ...
July 11, 2024 at 6:12 PM. HOUSTON (AP) — About half a million Houston-area homes and businesses will still be without electricity next week, the city's largest utility said Thursday, stoking the ...
These are the items Americans lose most. Perhaps unsurprisingly, the most commonly lost items were also among the most ubiquitous and important: phones and keys. Most people don't leave home ...
The temperature was already above 80 degrees and rising. The work of maintaining the public water supply in a heat wave is crucial. But it needs to be done as safely as possible. That means ...
Pins from left to right are: gate (logic-level), drain, source. The top metal tab is the drain, same as pin 2. [ 1] A power MOSFET is a specific type of metal–oxide–semiconductor field-effect transistor (MOSFET) designed to handle significant power levels. Compared to the other power semiconductor devices, such as an insulated-gate bipolar ...
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 ...
