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.
A power supply is an electrical device that supplies electric power to an electrical load. The main purpose of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load. As a result, power supplies are sometimes referred to as electric power converters.
A voltage regulator is a system designed to automatically maintain a constant voltage. It may use a simple feed-forward design or may include negative feedback. It may use an electromechanical mechanism, or electronic components. Depending on the design, it may be used to regulate one or more AC or DC voltages.
Static VAR compensator. In Electrical Engineering, a static VAR compensator ( SVC) is a set of electrical devices for providing fast-acting reactive power on high-voltage electricity transmission networks. [1] [2] SVCs are part of the flexible AC transmission system [3] [4] device family, regulating voltage, power factor, harmonics and ...
In the inverting topology, the output voltage is of the opposite polarity than the input. This is a switched-mode power supply with a similar circuit configuration to the boost converter and the buck converter. The output voltage is adjustable based on the duty cycle of the switching transistor. One possible drawback of this converter is that ...
Its function is to supply a stable voltage (or less often current), to a circuit or device that must be operated within certain power supply limits. The output from the regulated power supply may be alternating or unidirectional, but is nearly always DC (direct current).[1] The type of stabilization used may be restricted to ensuring that the ...
