2. 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]

3. Solar inverter - Wikipedia

   en.wikipedia.org/wiki/Solar_inverter

   Internal view of a solar inverter. Note the many large capacitors (blue cylinders), used to buffer the double line frequency ripple arising due to single-phase ac system.. A solar inverter or photovoltaic (PV) inverter is a type of power inverter which converts the variable direct current (DC) output of a photovoltaic solar panel into a utility frequency alternating current (AC) that can be ...

4. Mains electricity by country - Wikipedia

   en.wikipedia.org/wiki/Mains_electricity_by_country

   Frequency and voltage supplied to most premises by country. Mains electricity by country includes a list of countries and territories, with the plugs, voltages and frequencies they commonly use for providing electrical power to low voltage appliances, equipment, and lighting typically found in homes and offices.

5. HVDC converter - Wikipedia

   en.wikipedia.org/wiki/HVDC_converter

   A complete HVDC system always includes at least one converter operating as a rectifier (converting AC to DC) and at least one operating as an inverter (converting DC to AC). Some HVDC systems take full advantage of this bi-directional property (for example, those designed for cross-border power trading, such as the Cross-Channel link between ...

6. 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.

7. Variable-frequency drive - Wikipedia

   en.wikipedia.org/wiki/Variable-frequency_drive

   Small variable-frequency drive Chassis of above VFD (cover removed). A variable-frequency drive (VFD, or adjustable-frequency drive, adjustable-speed drive, variable-speed drive, AC drive, micro drive, inverter drive, variable voltage variable frequency drive, or drive) is a type of AC motor drive (system incorporating a motor) that controls speed and torque by varying the frequency of the ...

8. Split-phase electric power - Wikipedia

   en.wikipedia.org/wiki/Split-phase_electric_power

   Fig. 1 Fig. 2. A transformer supplying a three-wire distribution system has a single-phase input (primary) winding. The output (secondary) winding has a center tap connected to a grounded neutral.

9. Buck converter - Wikipedia

   en.wikipedia.org/wiki/Buck_converter

   A buck converter or step-down converter is a DC-to-DC converter which decreases voltage, while increasing current, from its input to its output . It is a class of switched-mode power supply . Switching converters (such as buck converters) provide much greater power efficiency as DC-to-DC converters than linear regulators , which are simpler ...
