2. Synchronverter - Wikipedia

   en.wikipedia.org/wiki/Synchronverter

   A synchronous generator’s rotating mass acts as a bank of kinetic energy for the grid to counteract changes in frequency – it can either provide or absorb power from the grid – caused by an imbalance of electric power supply and demand – in the form of kinetic energy by speeding up or slowing down.

3. Ring oscillator - Wikipedia

   en.wikipedia.org/wiki/Ring_oscillator

   A schematic of a simple 3-inverter ring oscillator whose output frequency is 1/(6×inverter delay). A ring oscillator is a device composed of an odd number of NOT gates in a ring, whose output oscillates between two voltage levels, representing true and false. The NOT gates, or inverters, are attached in a chain and the output of the last ...

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. [1]

5. Synchronization (alternating current) - Wikipedia

   en.wikipedia.org/wiki/Synchronization...

   The sequence of events is similar for manual or automatic synchronization. The generator is brought up to approximate synchronous speed by supplying more energy to its shaft - for example, opening the valves on a steam turbine, opening the gates on a hydraulic turbine, or increasing the fuel rack setting on a diesel engine.

6. Capability curve - Wikipedia

   en.wikipedia.org/wiki/Capability_curve

   Capability curves for generators with full converters: D-shape (red), rectangular (green), triangular (blue) The inverter-based resources (like solar photovoltaic (PV) generators, doubly-fed induction generators and full-converter wind generators, also known as "Type 3" and "Type 4" turbines [5]) need to have reactive capabilities in order to contribute to the grid stability, yet their ...

7. Inverter (logic gate) - Wikipedia

   en.wikipedia.org/wiki/Inverter_(logic_gate)

   Voltage transfer curve for a 20 μm inverter fabricated at North Carolina State University. Digital inverter quality is often measured using the voltage transfer curve (VTC), which is a plot of output vs. input voltage. From such a graph, device parameters including noise tolerance, gain, and operating logic levels can be obtained.

8. Noise generator - Wikipedia

   en.wikipedia.org/wiki/Noise_generator

   Zener diode based noise source. A noise generator is a circuit that produces electrical noise (i.e., a random signal). Noise generators are used to test signals for measuring noise figure, frequency response, and other parameters. Noise generators are also used for generating random numbers. [1]

9. Phase noise - Wikipedia

   en.wikipedia.org/wiki/Phase_noise

   Pink noise is sometimes called Flicker noise, or simply 1/f noise. The integral linewidth takes Voigt lineshape, a convolution of the white noise-induced Lorentzian lineshape and the pink noise-induced Gaussian lineshape. Pink noise provides a Allan Deviation plot at moderate averaging times. This flat line on the Allan Deviation plot is also ...
