  2. Voltage converter - Wikipedia

    en.wikipedia.org/wiki/Voltage_converter

    A simple voltage dropper can be used to reduce the voltage for low-power devices; if more than 12V is required, or for high-powered devices, a switched-mode power supply is used. The output will usually be DC in the range 1.5–24 V. Power supplies that output either 100–120 V AC or 210–240 V AC are available; they are called inverters ...

  4. Power inverter - Wikipedia

    en.wikipedia.org/wiki/Power_inverter

    A power inverter, inverter, or invertor is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC). [1] The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of rectifiers which were originally large electromechanical devices converting AC to DC. [2]

  5. AS/NZS 3112 - Wikipedia

    en.wikipedia.org/wiki/AS/NZS_3112

    AS/NZS 3112 is the harmonised/joint Australian and New Zealand Standard for AC power plugs (male) and sockets (female). The International Electrotechnical Commission (IEC) "world plugs" website defines this design as Plug Type I'. The plug consists of two flat pins forming an inverted V-shape, plus a vertical earthing pin below of a slightly ...

    South African National Standard 164: Plugs and socket outlets for household and similar purposes for use in South Africa is the South African Bureau of Standards' standard for domestic AC power plugs and sockets. As a former British colony, South Africa's electricity standards are of British derivation, and it uses 220/230 V at 50 Hz AC. [1]

  7. Grid-tie inverter - Wikipedia

    en.wikipedia.org/wiki/Grid-tie_inverter

    Inverters that target commercial applications are available for 208, 240, 277, 400, 480 or 600 VAC and may also produce three phase power. Peak efficiency: The peak efficiency represents the highest efficiency that the inverter can achieve. Most grid-tie inverters on the market as of July 2009 have peak efficiencies of over 94%, some as high as ...

  8. Rotary converter - Wikipedia

    en.wikipedia.org/wiki/Rotary_converter

    1909 500 kW Westinghouse rotary converter. A rotary converter is a type of electrical machine which acts as a mechanical rectifier, inverter or frequency converter.. Rotary converters were used to convert alternating current (AC) to direct current (DC), or DC to AC power, before the advent of chemical or solid state power rectification and inverting.

    en.wikipedia.org/wiki/Synchronverter

    Typical control structures for a grid-connected power inverter.(a) When controlled as a voltage supply.(b) When controlled as a current supply. As shown in the figure 3, when the inverter is controlled as a voltage source, it consists of a synchronization unit to synchronize with the grid and a power loop to regulate the real power and reactive ...
