2. ASCO Power Technologies - Wikipedia

   en.wikipedia.org/wiki/ASCO_Power_Technologies

   With over 1400 employees and 500,000 square feet of manufacturing floor space, it is the world's largest manufacturer of power transfer switches. ASCO Power Technologies was founded in 1888 and developed the first commercially available automatic transfer switch in 1920. On November 1, 2017, ASCO Power Technologies was sold by Vertiv to ...

3. Switched-mode power supply - Wikipedia

   en.wikipedia.org/wiki/Switched-mode_power_supply

   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 ...

4. Droop speed control - Wikipedia

   en.wikipedia.org/wiki/Droop_speed_control

   Droop speed control is a control mode used for AC electrical power generators, whereby the power output of a generator reduces as the line frequency increases. It is commonly used as the speed control mode of the governor of a prime mover driving a synchronous generator connected to an electrical grid. It works by controlling the rate of power ...

5. Switched reluctance motor - Wikipedia

   en.wikipedia.org/wiki/Switched_reluctance_motor

   Switched reluctance motor. Switched reluctance motor with magnetic flux lines. The switched reluctance motor (SRM) is a type of reluctance motor. Unlike brushed DC motors, power is delivered to windings in the stator (case) rather than the rotor. This simplifies mechanical design because power does not have to be delivered to the moving rotor ...

6. Vacuum interrupter - Wikipedia

   en.wikipedia.org/wiki/Vacuum_interrupter

   In electrical engineering, a vacuum interrupter is a switch which uses electrical contacts in a vacuum. It is the core component of medium-voltage circuit-breakers, generator circuit-breakers, and high-voltage circuit-breakers. Separation of the electrical contacts results in a metal vapour arc, which is quickly extinguished.

7. Power semiconductor device - Wikipedia

   en.wikipedia.org/wiki/Power_semiconductor_device

   Power semiconductor device. A power semiconductor device is a semiconductor device used as a switch or rectifier in power electronics (for example in a switch-mode power supply). Such a device is also called a power device or, when used in an integrated circuit, a power IC. A power semiconductor device is usually used in "commutation mode" (i.e ...

8. Open energy system models - Wikipedia

   en.wikipedia.org/wiki/Open_energy_system_models

   SWITCH is a loose acronym for solar, wind, conventional and hydroelectric generation, and transmission. SWITCH is an optimal planning model for power systems with large shares of renewable energy. SWITCH is being developed by the Department of Electrical Engineering, University of Hawaiʻi at Mānoa, Hawaii, USA.

9. Gate turn-off thyristor - Wikipedia

   en.wikipedia.org/wiki/Gate_turn-off_thyristor

   anode, gate, cathode. Electronic symbol. A gate turn-off thyristor (GTO) is a special type of thyristor, which is a high-power (e.g. 1200 V AC) semiconductor device. It was invented by General Electric. [1] GTOs, as opposed to normal thyristors, are fully controllable switches which can be turned on and off by their gate lead.
