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 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 ...
Power electronic substrate. The role of the substrate in power electronics is to provide the interconnections to form an electric circuit (like a printed circuit board ), and to cool the components. Compared to materials and techniques used in lower power microelectronics, these substrates must carry higher currents and provide a higher voltage ...
A tower type UPS with one IEC 60320 C14 input and three C13 outlets. A large data-center-scale UPS being installed by electricians. An uninterruptible power supply ( UPS) or uninterruptible power source is a type of continual power system that provides automated backup electric power to a load when the input power source or mains power fails.
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.
A power capacitor intended to be used in power electronic equipment and capable of operating continuously under non-sinusoidal current or voltage. power electronics. The field of electronics which deals with the conversion or switching of electric power with or without control of that power. principal arm.
In power supply design, a bridge circuit or bridge rectifier is an arrangement of diodes or similar devices used to rectify an electric current, i.e. to convert it from an unknown or alternating polarity to a direct current of known polarity. In some motor controllers, an H-bridge is used to control the direction the motor turns.
Recloser. Protective relay. v. t. e. In electrical engineering, power conversion is the process of converting electric energy from one form to another. A power converter is an electrical device for converting electrical energy between alternating current (AC) and direct current (DC). It can also change the voltage or frequency of the current.
