Inverter (electrical) — An inverter is an electrical device that converts direct current (DC) to alternating current (AC)[1]; the converted AC can be at any required voltage and frequency with the use of appropriate transformers, switching, and control circuits. Solid… … Wikipedia
Variable-frequency drive — A variable frequency drive (VFD) is a system for controlling the rotational speed of an alternating current (AC) electric motor by controlling the frequency of the electrical power supplied to the motor.cite book | first=Sylvester J. |… … Wikipedia
Digital phase converter — A digital phase converter creates a three phase power supply from a single phase supply. A digital signal processor (DSP) is used to control power electronic devices to generate a third voltage, which along with the single voltage from the supply … Wikipedia
