3. Vector inversion generator - Wikipedia

   en.wikipedia.org/wiki/Vector_inversion_generator

   A vector inversion generator (VIG) is an electric pulse compression and voltage multiplication device, allowing shaping a slower, lower voltage pulse to a narrower, higher-voltage one. VIGs are used in military technology, e.g. some directed-energy weapons , as a secondary stage of another pulsed power source, commonly an explosive-driven ...

4. Power inverter - Wikipedia

   en.wikipedia.org/wiki/Power_inverter

   To more clearly distinguish the inverters with outputs of much less distortion than the modified sine wave (three-step) inverter designs, the manufacturers often use the phrase pure sine wave inverter. Almost all consumer grade inverters that are sold as a "pure sine wave inverter" do not produce a smooth sine wave output at all, [citation ...

5. 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]

   Let the truth be known", the site allows competitors, and not just consumers, to post comments. The Ripoff Report home page also says: "Complaints Reviews Scams Lawsuits Frauds Reported, File your review. Consumers educating consumers", which allows a reasonable inference that the Ripoff Report encourages negative content.

   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 ...

9. Vector control (motor) - Wikipedia

   en.wikipedia.org/wiki/Vector_control_(motor)

   In vector control, an AC induction or synchronous motor is controlled under all operating conditions like a separately excited DC motor. [21] That is, the AC motor behaves like a DC motor in which the field flux linkage and armature flux linkage created by the respective field and armature (or torque component) currents are orthogonally aligned such that, when torque is controlled, the field ...
