A PCs power supply is an example of a piece of power electronics, whether inside or outside of the cabinet. Power electronics is the application of electronics to the control and conversion of electric power . The first high-power electronic devices were made using mercury-arc valves. In modern systems, the conversion is performed with ...
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 ...
The IGBT accounts for 27% of the power transistor market, second only to the power MOSFET (53%), and ahead of the RF amplifier (11%) and bipolar junction transistor (9%). [39] The IGBT is widely used in consumer electronics , industrial technology , the energy sector , aerospace electronic devices, and transportation .
Commutation cell. The commutation cell is the basic structure in power electronics. It is composed of two electronic switches (today, a high-power semiconductor, not a mechanical switch). It was traditionally referred to as a chopper, but since switching power supplies became a major form of power conversion, this new term has become more popular.
In power engineering, a single-line diagram ( SLD ), also sometimes called one-line diagram, is a simplest symbolic representation of an electric power system. [ 1][ 2] A single line in the diagram typically corresponds to more than one physical conductor: in a direct current system the line includes the supply and return paths, in a three ...
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 ...
A low-dropout regulator ( LDO regulator) is a type of a DC linear voltage regulator circuit that can operate even when the supply voltage is very close to the output voltage. [ 1] The advantages of an LDO regulator over other DC-to-DC voltage regulators include: the absence of switching noise (in contrast to switching regulators ); smaller ...
Additional to the traditional screw contacts the electrical connection between the module and other parts of the power electronic system can also be achieved by pin contacts (soldered onto a PCB), press-fit contacts pressed into PCB vias, spring contacts that inherently press on contact areas of a PCB or by pure pressure contact where corrosion-proof surface areas are directly pressed together ...
