Single- and three-phase alternating current (AC) motor speed can be controlled by controlling the frequency of the voltage coming to it. Motor speed has a lot to do with the capacity of refrigeration ...

A phase vector or phasor in physics and engineering signifies a sine wave whose amplitude and frequency are time-variant. The behavior of a sinusoid is decomposed by phasors into three independent ...

Almost all off line switching power supplies over several kilowatts of output power use a three phase bridge rectifier. Typically, it comprises a six diode bridge and a DC bus filter capacitor. A ...
