  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.

  3. Induction generator - Wikipedia

    en.wikipedia.org/wiki/Induction_generator

    An induction generator produces electrical power when its rotor is turned faster than the synchronous speed. For a four-pole motor (two pairs of poles on stator) powered by a 60 Hz source, the synchronous speed is 1800 rotations per minute (rpm) and 1500 RPM powered at 50 Hz. The motor always turns slightly slower than the synchronous speed.

  4. Inverter-based resource - Wikipedia

    en.wikipedia.org/wiki/Inverter-based_resource

    An inverter-based resource (IBR) is a source of electricity that is asynchronously connected to the electrical grid via an electronic power converter ("inverter"). The devices in this category, also known as converter interfaced generation ( CIG ), include the variable renewable energy generators (wind, solar) and battery storage power stations ...

  5. Electric motor - Wikipedia

    en.wikipedia.org/wiki/Electric_motor

    An electric motor is a machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft. An electric generator is mechanically identical to an electric ...

  6. Synchronverter - Wikipedia

    en.wikipedia.org/wiki/Synchronverter

    A simple diagram of synchronverter operation environment. Synchronverters or virtual synchronous generators[1][2] are inverters which mimic synchronous generators (SG) [3] to provide "synthetic inertia" for ancillary services in electric power systems. [4] Inertia is a property of standard synchronous generators associated with the rotating ...

  7. Electric generator - Wikipedia

    en.wikipedia.org/wiki/Electric_generator

    Electric generator. U.S. NRC image of a modern steam turbine generator (STG). In electricity generation, a generator[1] is a device that converts motion-based power (potential and kinetic energy) or fuel-based power (chemical energy) into electric power for use in an external circuit. Sources of mechanical energy include steam turbines, gas ...
