Power Supplies Types - Switched-mode Power Supply
... In a switched-mode power supply (SMPS), the AC mains input is directly rectified and then filtered to obtain a DC voltage ... The resulting DC voltage is then switched on and off at a high frequency by electronic switching circuitry, thus producing an AC current that will ... filter capacitors that are much smaller, lighter, and less expensive than those found in linear power supplies operating at mains frequency ...
Switched-mode Power Supply
... A switched-mode power supply (switching-mode power supply, SMPS, or 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 source, like mains power, to a load, such as a personal computer, while converting voltage and ... Unlike a linear power supply, the pass transistor of a switching-mode supply continually switches between low-dissipation, full-on and full-off states, and spends ...
Switched-mode Power Supply - Power Factor
... See also power factor Simple off-line switched mode power supplies incorporate a simple full-wave rectifier connected to a large energy storing capacitor ... portion of the AC cycle the capacitor provides energy to the power supply ... As a result, the input current of such basic switched mode power supplies has high harmonic content and relatively low power factor ...

Famous quotes containing the words power, switched and/or mode:

    Do not say to yourself, “My power and the might of my own hand have gotten me this wealth.” But remember the LORD your God, for it is he who gives you power to get wealth, so that he may confirm his covenant that he swore to your ancestors, as he is doing today.
    Bible: Hebrew, Deuteronomy 8:17,18.

    When I am on a stage, I am the focus of thousands of eyes and it gives me strength. I feel that something, some energy, is flowing from the audience into me. I actually feel stronger because of these waves. Now when the play’s done, the eyes taken away, I feel just as if a circuit’s been broken. The power is switched off. I feel all gone and empty inside of me—like a balloon that’s been pricked and the air’s let out.
    Lynn Fontanne (1887–1983)

    If Thought is capable of being classed with Electricity, or Will with chemical affinity, as a mode of motion, it seems necessary to fall at once under the second law of thermodynamics as one of the energies which most easily degrades itself, and, if not carefully guarded, returns bodily to the cheaper form called Heat. Of all possible theories, this is likely to prove the most fatal to Professors of History.
    Henry Brooks Adams (1838–1918)
