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]
The only difference between DTC and DSC is the shape of the path along which the flux vector is controlled, the former path being quasi-circular whereas the latter is hexagonal such that the switching frequency of DTC is higher than DSC. DTC is accordingly aimed at low-to-mid power drives whereas DSC is usually used for higher power drives. [6 ...
William McMurray (1929–2006) was a pioneer in the field of power electronics. Holding both British and American citizenship, he was an electrical engineer, author and inventor who held 23 patents, and was most notable for his invention of the McMurray inverter and the McMurray-Bedford inverter.
Toyota may supply independent mechanics with parts and instructions for repairing, but not replacing, potentially faulty inverters on certain 2014 Prius models, Green Car Reports has learned.
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 ...
The direct-quadrature-zero (DQZ, DQ0 [1] or DQO, [2] sometimes lowercase) or Park transformation (named after Robert H. Park) is a tensor that rotates the reference frame of a three-element vector or a three-by-three element matrix in an effort to simplify analysis.

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 ...
